80 W. Theobald — On Indian and Burmese species of Triomjx. [March, 



much commoner than the last m Burmah, but moat rare, if not altogether 

 wantmg, in India. T give what I believe the the synonymy of this species, 

 and must premise that in this case, as in the others, I have not attempted 

 to evolve the less obvious synonyms, as mere speculations, witliout access to 

 original figures, decriptions, or specimens, are of little value.

Leik. heywoon, of the Burmese. 

 The type specimen was obtained alive by myself in the Arakan range, 

 west of Pegu, the dried shell being presented by me to the Bristol Museum, 

 and the skull to the British Museum. The history of this skull I must now 

 endeavour to unravel, not less successfully, let me hope, than I did in the 

 case of Testudo {Sca2)hia') Falconeri, which, thanks to my observation thereon, 

 has now been restored by the Trustees of the British Museum to the Imperial 

 Museum, Calcutta. Vide Appendix to Catalogue of Shield Reptiles, 1872, 

 p. 10, et ante. In the first place, I may state, as a matter of fact, that but 

 two skulls (exclusive of young animals in spirit) of Trionyx passed from my 

 hands into Dr. Gray's, either by gift or purchase, from the simple fact that 

 I only brought home two from Burmah with me, viz., 1st, a head of 2V, 

 stellatus, as mentioned above, which Dr. Gray refers to Tr. Jiurum in his paper 

 on the Mud Tortoises of India, in the Annals for 1872, p. 336, and probably 

 alludes to without naming as " skull of an adult" in the Proceedings of 

 Zoological Society, 1869, p. 217 ; and, 2nd, the skull of my type of Tr. 

 JPhayrei, presented by me to the British Museum in 1868 (or 67 ), which Dr. 

 Gray doubtfully refers to Tr. Jiurum (erroneously as I believe), and which 

 he also indentifies (correctly no doubt) with his Tr. jeudi. How comes it 

 then I may ask that ; with the type skull of my Tr. Fhayrei, furnished him 

 by myself, he describes another B'^QomiQ-n. 2^b Tr.jeudi ? In courtesy, and 

 to avoid confusion and multiplication of names. Dr. Gray should have given 

 such amended characters as he chose, but without altering the name of my 

 type already published in the Journal of the Linnean Society. It is true Dr. 

 Gray remarks (Annals and Magazine of Natural History. 1872, p. 336) of 

 my type skull: — " It certainly is not the skull of the species described under 

 that name in the Journal of the Linnean Society, nor of the Tortoise described 

 under that name by Dr. Anderson." To this I can only say that till Dr. 

 Gray gives some reasonable ground for this statement, I must be allowed tp 

 say that I believe it is ; and this I say, knowing what my own type was like,
