Taxonomic differentiation of the species in this 

 genus is not definitive or convincing. Fraser- 

 Brunner (1949:1050) synonymized H. atratum 

 (Garman) with 77. reinhardti (Liitken). There 

 are indications, from other studies, that these two 

 species are distinct (E. H. Ahlstrom, personal 

 communication). The above specimens appear to 

 represent either one or both of the cited nominal 

 species.

The records of capture shown on the chart sug- 

 gest that D. atlanticus is a northern species in this 

 area and D. laternatus is a southern species. 

 Records from other collections show that in waters 

 farther offshore than sampled by the survey, the 

 distribution of D. atlanticus extends southward at 

 leasttolat.20°N.
