TESTUDINATA. 



Geoclemys subtrijuga (Schlegel en MfrLLEE).

 chelonians * * * Brit. Mus., 1889, p. 94. 



Type locality: — Java. 



Three examples from Depok, Java, in the Bryant collection. 



This species is mentioned (p. 23) on account of its interesting distribution. 

 It is one of the many species which occur on Java and the Asiatic mainland 

 without as yet having been found in either Sumatra or Borneo. 



Orlitia crassicollis (Gray). 

 Gr.\y, Synop. Rept., 1831, p. 21. Bodlengee, Cat. chelonians * * * Brit, mus., 1889, p. 98. 



Type locality: — Sumatra. Boulenger records the shell of a half-grown 

 individual in the British museum, the gift of Thomas Bell, Esq., as being the 

 type from Sumatra. 



Bryant sent two examples from Depok. The species does not appear to 

 have been taken in Java previously. Being unfamiliar with East Indian fresh- 

 water tortoises and having but httle identified material at hand for comparison, 

 I concluded that I had to deal with what is generally called Cyclemys dhor (Gray) 

 (Blgr. loc. cit., p. 131). In this, as in many other matters. Dr. Stejneger set me 

 aright; but our study and discussion of the latter species led to some interesting 

 results affecting this name, so long used. Gray's Synopsis Reptihum is not in 

 the library of the M. C. Z., but I have the following information sent me by Dr. 

 Stejneger taken from his copy of this rare work. 



In the first place Boulenger {loc. cit., 1889, p. 131), alluding to the original 

 description of Cyclemys dhor refers to Gray, Synopsis Reptilium, 1831, p. 23. 

 This is an error, the description being on p. 20. Concerning this name and the 

 type locality of the species. Dr. Stejneger writes me that he has come to the 

 following conclusion: — 



" Gray' g Emys dhor, p. 20, corrected to E. dentata on pp. 79 and SO, and 

 figured on pis. 8 and 9, is a compound based in part upon (Hardwicke's drawing 

 of) a Bengal specimen, and in part upon three young (apparently from Java).
