The Challenger collection includes ten specimens of this species : seven of them, five 
of which are males and two females, from Pokoska, Japan, captured in the trawl in from 
5 to 25 fathoms of water; one male specimen from Kobe, Japan, in 8 to 50 fathoms ; one 
female specimen from the Reefs at Honolulu ; and one female specimen taken in the trawl 
at Station 233b, Inland Sea, Japan; May 26, 1875, lat. 34° 18' N., long. 133° 35' E. ;

The tip of the first abdominal appendage of an adult male, Squilla empusa, is
