Catalogue of Reptiles 91 



feet across, I never believed it contained a crocodile, as my boatmen 

 assured me was the case. However I fired and a lashing of water Was 

 heard m tin- hole- What I aimed at was still visible, so I fired again, 

 seemingly without effect, but on going op, I hauled out a dead crocodile 

 with two balls through the brain. This was G. trigonops, and lam 

 not aware that animals of the larger species excavate holes for them- 

 selves, as this one does. It may very likely be the "smaller c Mle" 

 said to inhabit; streams on the table land of Rhbtas Ghur. 



Thirdly, of Grocodihis pahx on, the Museum possesses a splen- 



did smte of specimens; 3 stuffed specimens, 4 in spirit, a tine skeleton 

 and 8 skulls, h is emphatically "the crocodile" of Lower Bengal. 1 have 

 procured one specimen at Thaiet-mio, but ii is raiv in Lower Pegu. I 

 tio reason for doubting the conclusion of Prof. Huxley that C. 

 owntofronsj Gray, is a synonym of this species, one of the types hi 

 been ivc.mv.m1 from the Asiatic Society^ Museum, which is rich in P. 

 falMstria, and the trivial name bombifrone Is very applicable, especially 

 to the adult animal. Some few heads are rather narrower than others, 



probably 1. 'males, but cannot, well be confounded with G. porosus even 

 were no other parts than the skulls preserved. If 1 am correct in 

 referring the above specim trigonops, it is utterly past my 



comprehension how Gfunther has referred 6. trigonops as asynonym 

 of G. palustris. C. porosis is nearer C. pahtstris than G. trigonops to 

 either. I am not quite clear, however, if the stuffed specimen 2a belongs 

 to the species. The praamaxillary suture appears to be straight, but 

 still I am not certain of my reference. 



I subjoin some measurement of a series of skulls.
