Leptodius crassimanus, A. M. -Edwards, Nouv. Arch, du Mus., 

 t. ix., p. 226, pi. xi., fig. 4. 



Carapace broad, moderately convex, and marked with broad 

 and well-defined inter-regional and inter-lobular grooves. Prpto- 

 gastric lobes transversed by a longitudinal sulcus ; uro-gastric 

 lobe prolonged to a point between them ; hepatic region bilobed. 

 Portion of the carapace situated behind the lateral angles almost 

 smooth. All the prominent portions of the carapace a little 

 rugose. Front straight, a little deflexed, and divided into four 

 small tuberculif orm teeth, the internal orbital angle not included. 

 Antero-lateral borders with five principal obtuse teeth, in front 

 of which is a sixth, small, prominence. Anterior legs of the 

 male much dilated and very robust ; hand thick, a little rugose 

 above ; fingers smooth, not carinated.

G-enus Chxoeoditjs, Leach. 



Carapace nearly regularly hexagonal, flat and smooth or 

 slightly lobulated near the antero-lateral borders. Front broad. 

 Antero-lateral borders thick, lobed or toothed. Basal joint of 

 the antennae broadly joined to the front ; orbital hiatus almost 

 closed by the close approximation of the inner angles of the 

 upper and lower orbital borders, so as to exclude the flagellum 

 of the antennas from the orbit. Anterior legs long and generally 

 smooth ; fingers spoon-excavate.
