 specimen is an adult Trioni/.v Phaiire!^ and that as its skull, 

 after caretuUy CKinparini; it with the skull of Trionyx JeuJii, 

 is found to agree with the latter in its structural details, 1 am 

 forced to accept the conclusion that Gray's 2\ Jeudii is only 

 T. P/idi/nt' nuiU'V another luime. 



Dr. (^ray, after stating that he is aware that the sternal 

 callosities of Trionyx change much during growth, again in- 

 troduces the assertion that Mr. Theo])ald had remarked that 

 his T. Pluvfrti had the lateral linear callosities of T. suhplanns^ 

 a statement which 1 do not find, as I have already observed, 

 in any description of Theobald's relating to 2\ Phayrci. llow 

 is this discrepancy to be reconciled ? 



1 am perfectly aware that ^Ir. Theobald does not describe 

 any anal callosities ; but I have given such details regarding 

 the callosities and the adult characters of the species as have 

 enabled Dr. Gray, notwithstanding his assertion that I deal 

 only in generic characters, to refer it to the genus Landenunu'a 

 and to the species ^>ey('ce//a/»s — by some process of mental 

 legerdemain, if he is consistent in saying that I have not 

 given any specific characters ! 



At that point in his article where he amves at the conclu- 

 sion that the specimen of T. Phayrei described by me has no 

 alhnity with T. Phayrei^ Theobald, Dr. Gray unconnectedly 

 diverges to consider my views on the genus Macroxus, Cuvier, 

 as accepted by him, and, having stated his views on that sub- 

 ject, betakes himself to T. Jeudii^ from the consideration of 

 which he again returns to the charge regarding T. Phayrei, 

 associating with it some remarks regarding his estimate of the 

 state of science in the Imperial Museum of Calcutta, with a 

 notice of my official position in the capital of India. I shall 

 follow Dr. Gray in his ramble, and first consider his state- 

 ments regarding the squirrels. 



Dr. Gray, in adopting the genus Macroxus, docs so, to use 

 his own words, " as it is desirable to separate the squirrels 

 icith simple ears;^^ and he defines the genus as follows: — 

 " Head moderate, short ; nose rounded ; ears ovate, covered 

 with short adpresscd hairs ; front edge of the cutting-teeth com- 

 pressed, smooth. Limbs free. Tail as long as or longer than 

 the body and head, covered with long spreading hair." And 

 the genus Sciurus as folloAvs : — '^ Ears tufted. Head broad ; 

 muzzle short. Feet hairy at the heels. Front upper molar 

 small or often wanting." Dr. Gray says I objected to the
