Dorsal shield completely bony, exoskeleton consisting of irreg- 
ular, juxtaposed, mosaiclike plates. Plastral elements eight; no 
entoplastron ; legs paddle-shaped, clawless, digits of foreleg much 
elongated; phalanges without condyles; beak with two triangular 
cusps, between three deep notches; no enlarged alveolar surface, 
jaws simply sharp-edged; head covered with small shields; cara- 
pace with seven keels, plastron with five. 
It is extremely difficult to determine whether there is more 
than one species belonging to this genus. Specimens belonging 
to the genus are found in temperate and tropical parts of the 
Atlantic and Pacific Oceans and in the Indian Ocean and the Medi- 
terranean Sea. Certain authors maintain that the Atlantic and 
Pacific forms are identical. Garman has separated the Atlantic 
and the Pacific forms and has given the name D. schlegelii to 
Specimens found in the Pacific and Indian Oceans, and Stejneger 
follows him in the retention of this name. R. A. Philippi 
has described a species, Sphargis angustata, from Chili.”
