Distribution. — Lat. 21° 12' N., long. 157° 49 / W., 295 fathoms, station 3472 (type locality); south 
coast of Oahu Island, 53 to 264 fathoms, stations 3810, 3813, and 3919; vicinity of Kauai Island, 164 to 399 
fathoms, stations 3984, 4021, and 4130; west coast of Hawaii Island, 233 to 198 fathoms, station 4044; 
north coast of Maui Island, 178 to 220 fathoms, stations 4080 and 4081; northwest coast of Oahu Island, 
154 to 282 fathoms, stations 4114, 4115, 4116, 4120, and 4121; southwest coast of Oahu Island, 192 to 
352 fathoms, station 4122. 
This species was based on a single male in which the chelipeds are very unequal ; a series of speci- 
mens shows that the right claw is abnormally reduced; in the normal individual the chelipeds are 
subequal in size, and similar except as to the fingers. Several examples larger than the type were 
secured in 1902; the largest, a male, station 4080, measures 40.1 mm. long and 55.2 mm. wide to tip" 
of spines.
