Catalogue of Bajjiihs. Gl? '7 



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

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

 heard in the hole. What I aimed at was still visible, so I fired again, 

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

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

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

 Belves, as this one does. It may very likely be the " small crocodile" 

 said to inhabit streams on the table land of Ehotas Ghur. 



Thirdly, of Crocodihis palustris, Lesson, the Museum possesses a splen- 

 did suite of specimens ; 3 stuffed specimens, 4 in spirit, a fine skeleton 

 and 8 skulls. It is emphatically " the crocodile' of Lower Bengal. I have 

 procured one specimen at Thaiet-mio, but it is rare in Lower Pegu. I 

 see no reason for doubting the conclusion of Prof. Huxley that G. 

 homhifrons, Gray, is a synonym of this species, one of the types having 

 been received from the Asiatic Society's Museum, which is rich in G, 

 palustris, and the trivial name bombifrons is very applicable, especially 

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

 probably females, but cannot well be confounded with G. ijorosus, even 

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

 referring the above specimens to G. trigonops, it is utterly past my 

 comprehension how Gunther has referred G. trigonous as a synonym 

 of G. paliistris, G. porosus is nearer G. palustris than G. trigonops to 

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

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

 still I am not certain of my reference. 



I subjoin some measurement of a series of skulls.
