Hab. India: Ganges (Dr. Sayer); Madras (Jerdon); Ceylon (Kelaart). 
The dorsal shields in four series, all equally keeled, with two irregular series of 
plates on the sides. The shields are often nearly of the same form and size; but 
sometimes there are larger and broader shields intermixed in and deranging the series, 
and at other times the whole vertebral series is formed of wider shields. 
This species has generally been confounded with Oopholis biporcatus and Crocodilus 
vulgaris. 
Crocodilus 
The face of the younger specimen is rugulose and depressed, with a deep pit on the 
sides over the eighth and ninth teeth; there are two arched ridges on each side behind 
the nostril, and some rugosities in front of the orbits. In the older skull the face is 
very convex and rounded, rugose, with some more or less distinct rugosities in front 
of the orbits, but not the distinct longitudinal ridge so characteristic of Oopholis porosus. 
Professor Owen described the peculiar form of the premaxillary in a skull in the 
College of Surgeons Museum, sent from Bengal by Dr. Wallich; but he refers the skull 
to Crododilus rhombifer of Cuvier, which is an American species. 
The smallest specimen in the British Museum is 19 inches, and the largest nearly 
10 feet long; there are skulls showing that it grows to a much larger size. The 
specimen I described as C. trigonalis is 244 inches long. 
In my Catalogue of the Tortoises and Crocodiles in the British Museum, published 
in 1844, I described it, from two adult skulls from India of 18 and 20 inches long, as a 
new species, which I called Crocodilus bombifrons, pointing out the straightness of the 
suture between the intermaxillary and the maxillary bones. I observed that I had 
seen in the Paris Museum a large specimen which had been described by Duméril and 
Bibron as an adult of Crocodilus biporcatus, which appeared to belong to this species, 
stating that it was immediately known from C. porosus by the breadth and convexity of 
the face.
