Cuvier in his essay gives the history of this species under the name of Le Crocodile a 

 museau effile, ou de Saint Domingue {Crocodilus acutus, nob.), Oss. Foss. v. 458, and 

 figures the skull at t. 1. f. 3 & I'J, and the nuchal shield at t. 2. f. 5. 



Professor Briihl described and figured the skeleton of this species in his work. There 

 is the skeleton of a well-grown specimen in the British Museum, and several skulls. 

 The central prominence of the hinder part of the muzzle is sometimes much less 

 developed than ui the typical skulls. 



** Face very slender. Dorsal plates nearly uniform. Nasal hones not produced quite 



to the nostrils. Temsacus. 



2. Molinia intekmedia (Orinoco Crocodile). (Plate XXXTI. figs. 4-6.) 

 Dorsal plates in six rows, all slightly and nearly equally elevated ; the keels of the two 

 vertebral series rather larger than the others, quadrilateral, rather broader than long ; the 

 lateral ones oval, with five or six large plates forming an interrupted line on the sides.

There is a young specimen in spirits in the British Museum, sent by M. Brandt, of 

 Hamburg, as Crocodilus acutus, and an adult skull, 20 inches long, received from Paris 

 as Crocodile de VOrenoque, and a second very large skull purchased in London. 



In my Catalogue of Tortoises and Crocodiles in the British Museum Collection, from 

 all I could then learn, I was induced to believe that the Crocodilus intermedius of 

 Graves was the same as the Crocodilus schlegelii of Borneo, and therefore called the 

 Bornean animal Mecistops journei. M. Dumeril, in his paper in the Archives du 

 Museum, not seeing the mistake, says that I refer the true Crocodilus intermedius to 

 the genus Mecistops, and suggests that Crocodilus acutus ought also to belong to it. 



M. Auguste Dumeril, for the purpose of comparing the head of this Crocodile with 

 that of Crocodilus leptorhynchus of West Africa, ga^•e a figure of the head and front part 

 of the back of the Crocodile de Journee, Archiv. du Mus. x. 173, t. 14. f 3 ; but it does 

 not appear whether it is from a specimen, or only an enlarged copy of the figure of
