Length of sexually mature individuals varies from 15 to 23 mm. 



In adults, the low dorsal keel running along the body forms small, 

 barely perceptible denticles on pereon somites III-VII and the somites 

 of the pleon. The structure of the distal part of the 6th segment of pere- 

 opods VI is usual but does not form the unique club in whose cleft the 

 retractile claw fits. 



Distribution: Northern, tropical, and southern regions of the Pacific 

 and Atlantic oceans and tropical regions of the Indian Ocean (including 

 the Arabian Sea and Bay of Bengal). The northernmost occurrence has 

 been reported from Davis Strait and the Bering Sea. A deepwater species, 

 known from 500-700 to 3,000-4,000 m but the maximum records relate 

 to 1,000-2,000 m depths. 



Lanceola loveni grossipes Shoemaker, 1945 (Fig. 12) 



Shoemaker, 1945a: 209; Vinogradov, 1957: 191, 1960a: 206. 

 Length of sexually mature females 27-29 mm. 

 Shoemaker (1945a), based on material from the Atlantic Ocean 

 (Bermuda Islands), identified the subspecies L. loveni grossipes, differing 

 from the typical form in the structure of pereopods VI and VII. Pere- 

 opods VI are relatively longer than in the typical form; the 6th segment 

 broadens distally to form a club in whose deep cleft the long and ctout 

 curved claw fits. Pereopods VII are half the length of pereopods VI. 

 Shoemaker had at his disposal eight specimens (size, sex, and age not 

 mentioned) of this subspecies, and used the sexually mature female, 

 29 mm long, as the type specimen. In the material examined by us the
