Var. australis, Giinther. 
Crocodile, Landsborough, Explor. of Australia, 1.70. 
Hab. North Australia (Elsey & Kraiq). 
Dr. Giinther has pointed out to me that all the Australian specimens which we have 
examined have one cross band of the shield less than the Indian specimens; that is to 
say, they have sixteen, and the Indian specimens seventeen bands of shields from the 
neck to the base of the tail. That is the case both in the small specimen in spirits and 
the large specimen, 173 feet long, which was procured by Mr. Kraig. 
In the British Museum there is the skin of an adult from N.E. Australia, another, 
13 feet long, received from the Zoological Society, and several (two-thirds half-grown) 
young specimens, stuffed, and several young specimens in spirits. 
The largest skull in the British Museum is 29 inches long; the adult skulls vary from 
29 to 31 inches in length; a half-grown species is 19 inches long. The skull 26 inches 
long, is said to be from an animal caught in Bengal that was 33 feet long. 
Cuvier figures the skulls cf young and half-grown specimens. S. Miller and Schlegel 
figure two skulls, one under the name of C. biporcatus (f. 6), and the other C. dipor- 
catus raninus (f. 7): the latter seems to be from an adult or aged animal; the former 
(f. 6) fiom a full-grown one before the skull is thickened and spread out. Another 
specimen, figured as C. diporcatus raninus (f. 8), appears to be from a specimen of 
Crocodilus or Bombifrons siamensis. It certainly is not an Oopholis, from the form of 
the dorsal scales and the presence of the nuchal ones. 
There is a good series of skulls of this species in the Museum of the College of 
Surgeons; but No. 725, named C. diporcatus in the Catalogue, is the skull of an adult 
Crocodilus vulgaris; and No. 713, called Crocodilus acutus in the Catalogue, is Oopholis 
porosus.
