said to be webbed. It was supposed to come from Congo; but 

 that is very doubtful. 



2. Palinia ? Moreletii. 

 Crocodilus Moreleiii, Dum. Arch, clu Mus. vi. 255, t. 20 ; Cat. Rept.28.n.5*. 



Dorsal scales keeled, nearly square ; scales of the sides and 

 limbs smooth, without tubercles. 



Hab. Yucatan, Lac Flores (M. Morelet). 



This species is from a specimen in the Museum of Paris, 

 which is very badly figured and indistinctly described in the 

 memoir above cited. 



There are two young specimens of Crocodiles, in spirit, with- 

 out habitats, in the British Museum, which are peculiar in the 

 large size of the nuchal shield, the strength of the keels of the 

 dorsal shields, and the large keeled scales of the fore-arms and 

 thighs, in which they agree with Palinia rhombifer ; but there is 

 so much difference between the two, and between them both and 

 the specimens of that species from Cuba, that I think they must 

 be left in doubt, for further elucidation. There are also two 

 small stuffed specimens in the Collection (purchased in shops, 

 and without any locality attached), which are peculiar in having 

 six series of uniform, squarish, very strongly keeled dorsal 

 scales : they are very unlike any other specimen in the Collec- 

 tion, and may be new ; but I do not like to describe them in the 

 present imperfect state of our knowledge. 



b. The intermaxillary bone elongate, produced and truncated behind ; the 

 suture sloping backwards and converging, and then transverse or sinuous. 

 Toes webbed. Legs with a fringe of elongated triangular scales. 



4. Crocodilus. 



Face oblong, depressed, without any ridge in front of the 

 orbits. Nuchal shields four, in an arched series. Cervical disk 

 rhombic, of six shields. Dorsal shields quadrilateral, as broad 

 as long ; the vertebral series rather the widest and most keeled.
