Readers may be surprised to learn that chapter nine of the current one hundred chapter edition of Journey to the West did not appear in the original version anonymously published by the Shidetang (世德堂) publishing house in 1592. Chapter nine of course tells the story of how Tripitaka‘s parents, his scholar-official father Chen Guangrui (陳光蕊) and mother Yin Wenjiao (殷溫嬌), meet (fig. 1); Guangrui’s murder and the pregnant Lady Yin’s kidnapping by a bandit; Tripitaka’s birth and Moses-like trip down a river (hence his nickname “River Float,” Jiang liu, 江流); his rescue, rearing, and initiation into the Buddhist order by the abbot of Gold Mountain; Lady Yin’s rescue and the bandit-turned-official’s arrest; and Tripitaka’s later reunion with his mother and father, the latter’s body having been preserved and brought back to life by heaven.
Some scholars, such as Glen Dudbridge, suggest the current ninth chapter is a forgery, having been written by one Zhu Dingchen (朱鼎臣) of Canton because it appears in his
slightly later edited version of the novel titled The Chronicle of Deliverances in Tripitaka Tang’s Journey to the West (Tang Sanzang Xiyou shi ni zhuan, 唐三藏西游释尼傳, circa 1595). (See the 01-02-21 update for new information about Zhu’s version of the novel.) Other scholars posit there is internal textual evidence for a possible lost chapter and that the current ninth chapter was salvaged from these internal clues.

Anthony Yu‘s (1975) paper “Narrative Structure and the Problem of Chapter Nine in the ‘Hsi-Yu Chi'” supplements previous analyses of said internal textual evidence. He demonstrates that references to the Chen Guangrui episode litter the book. For example, a poem in chapter twelve (ch. 11 of the original Shidetang version) reads:
Gold Cicada was his former divine name.
As heedless he was of the Buddha’s talk,
He had to suffer in this world of dust,
To fall in the net by being born a man.
He met misfortune as he came to Earth,
And evildoers even before his birth.
His father: Chen, a zhuangyuan  from Haizhou.
His mother’s sire: chief of this dynasty’s court.
Fated by his natal star to fall in the stream,
He followed tide and current, chased by mighty waves.
At Gold Mountain, the island, he had great luck,
For the abbot, Qian’an, raised him up.
He met his true mother at age eighteen,
And called on her father at the capital.
A great army was sent by Chief Kaishan
To stamp out at Hongzhou the vicious crew.
The zhuangyuan Guangrui escaped his doom:
Son rejoined sire—how worthy of praise!
They saw the emperor to receive his grace;
Their names resounded in Lingyan Tower.
Declining office, he chose a monk’s life
At Hongfu Temple to seek the true Way,
This old Buddha-child, nicknamed River Float,
With a religious name of Chen Xuanzang. 
Yu (1975) notes “this passage…which introduces Tripitaka to the reader, has, with the exception of one major discrepancy (i.e. the name of the monk who took in the river-borne orphan), all the crucial elements constitutive of the Chen Guangrui story” (p. 296).
After providing several more examples, he concedes external textural evidence for a lost chapter has yet to be discovered, but suggests the author-compiler of the Journey to the West was surely familiar with established Yuan-Ming dramas involving Tripitaka’s birth and life:
I think that the foregoing analysis, admittedly brief, is sufficient to show the significance, if not the indispensability, of the Chen Guangrui episode in the narrative, though as I have remarked earlier, these later allusions certainly cannot be construed as incontrovertible proofs for a “lost chapter.” The existence of such a chapter has to be established by further discovery of textual materials hitherto unknown, if such discovery is indeed still possible. It may be safely asserted, however, that the author of the hundred-chapter novel, Wu Cheng’en or whoever he might be, is thoroughly familiar with the tradition of the birth and adventures of the infant Xuanzang popularized in the dramas of Yuan and Ming China, and that he has consciously and skillfully exploited this tradition in his narrative (Yu, 1975, p. 306).
Yu (1975) goes on to counter Dudbridge’s criticism that the Chen Guangrui episode doesn’t progress the overall plot by saying it should, instead, be accepted as an “organizing principle”, one that explains the reason for the monk’s ordeals:
[T]he theme of the river and its attendant perils utilized by the author of the hundred-chapter novel reinforces the theme of Tripitaka’s this-worldly identity as the incarnation of the banished Gold Cicada. Both themes in turn support the threefold aetiology developed in the narrative for explicating the meaning of Tripitaka’s ordeals: as a form of chastisement for his preexistent transgression, as a test of endurance for the earthly pilgrim, and as an exemplum of the high cost of obtaining sacred writings from the West (p. 307).
Furthermore, he counters Dudbridge’s claim that the concept of a lost chapter would be stronger if the novel provided more than just passing references to background info of the central characters. In fact, the novel does provide lengthy info on our heroes. For example, Yu (1975) presents a very long poem from chapter nineteen detailing Zhu Bajie’s life, from his early Daoist training, achievement of immortality, and rise to heavenly rank to his drunken flirting with the moon goddess (fig. 2), banishment from heaven, and mistaken reincarnation on earth as a pig-man.

In the end, Yu (1975) states Qing-era editors of the novel were justified in their suspicion of a lost chapter given the lack of detailed info about Tripitaka’s life, unlike the other pilgrims:
In the absence of chapter 9, Tripitaka is the only member of the pilgrimage, in fact, whose origins are presented in the manner which Dudbridge ascribes to the disciples: in allusion or indirectly, in moments of retrospect. The early editors of the Xiyouji, therefore, were not wholly unjustified in their protest that a theme of such significance as the Chen Guangrui story had not been more fully accounted for by antecedent narrative (p. 310).

Zhu Dingchen’s edition of Journey to the West actually predates the 1592 edition. This shows that the aforementioned internal clues in the 1592 edition are based on previous material.
I’ve archived a book that shows how Tripitaka’s exile from heaven is similar to ancient Greek and Egyptian beliefs.
I’ve posted an entry discussing the characterization of Tripitaka as a Confucian in the novel.
