DB. J. E. GEAT'S SYNOPSIS OF THE SPECIES 



M. Bory de St. Vincent. If the latter, it is so embellished that one is unable to recognize 

 its origin.

 strongly keeled on each side, and nearly continuous with the dorsal shield. Legs 

 fringed. Toes loehled. Abnormal Crocodiles. 

 * Face broad ; nasal bone produced into the nostril. Alligatorian Crocodiles. 



6. Halcuosia. 



The premaxillary suture transverse, rather convex backwards. Nasal bones produced 

 beyond .the intermaxillary, and forming a bony septum between the nostrils. The 

 palatine bone produced to the same level as the lateral opening — that is, to the lateral 

 inflection of the skull. The face oblong, broad, without any ridge in fi-ont of the orbit. 

 Eyelids with two bony plates. Nuchal plates four, m a cross row, strongly keeled. 

 Cervical plates three or four pairs, forming a ridge on each side, the hinder one smaller. 

 Dorsal plates in foui' series ; the central broad, slightly keeled, the outer narrow, dis- 

 tinctly keeled ; sides with large convex scales.

It has the square head and the elongated cervical sliield formed of single pairs of 

 scutella, and the bony eyelids, of the Alligators with bony eyelids ; but it is a Crocodile, 

 and there are two bones in the eyelid instead of one as in Caiman jxilpebrosus.
