Cuvier in his essay gives the history of this species under the name of Le Crocodile a 
museau effilé, ou de Saint Domingue (Crocodilus acutus, nob.), Oss. Foss. v. 458, and 
figures the skull at t. 1. f. 3 & 14, 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 in the typical skulls. 
** Face very slender. Dorsal plates nearly uniform. Nasal bones not produced quite 
to the nostrils. ‘'Temsacus. 
2. MOoLInIA INTERMEDIA (Orinoco Crocodile). (Plate XXXII. figs. 4—6.) 
Dorsal plates in six rows, all slightly and nearly equally elevated; the keels of the two 
yertebral 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  Orénoque, 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. Duméril, in his paper in the Archives du 
Muséum, 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 Duméril, for the purpose of comparing the head of this Crocodile with 
that of Crocodilus leptorhynchus of West Africa, gave a figure of the head .and front part 
of the back of the Crocodile de Journée, Archiv. du Mus. x. 173, t. 14. £3; but it does 
not appear whether it is from a specimen, or only an enlarged copy of the figure of
