between D. curtus and D. litus, particularly with regard to the body 

 shape, the female and male fifth legs, and the third legs. Evidence of 

 similarity between D. ulua and D. bifurcatus also exists in the armature 

 of the fii'st fom' thoracic legs. 



While the geographic distribution of the four species is not fully 

 known, the reported localities (see table 13) suggest some rather 

 interesting problems, especially with regard to the morphological 

 similarity between D. curtus and D. litus. D. curtus has been reported 

 from the tropical and subtropical Atlantic, D. litus has been described 

 from specimens captured at Eniwetok Atoll in the Pacific and has not 

 been found on Hawaiian fishes. It would be of interest to determine 

 whether either of the two species, or a similar species, occurs on fishes 

 in the Indian Ocean or on fishes from the west coast of Africa.

Key to the Species of Dentigryps 



The following key has been constructed to include both sexes of 

 the four species discussed in this paper. The characters based on 

 the fifth leg of the female and male of D. curtus and D. litus are some-
