 pairs of legs are gressorial, and are provided with spines on the 

 ischium, merus. carpus, and propodus. 



Only one specimen was obtained in 1902 from Kauai Island, the 

 Hawaiian Islands, bv the U. S. Fish Commission steamer A/ha from.

 This species approximates more closely to 

 ^ga incisa"' Schioedte and Meinert than to any 

 other described species of the genus. It differs, 

 however, in the shape of the abdomen, which 

 is more triangular in A. incisa; in the shape 

 of the terminal notch, which is V-shaped in A. 

 Incisa^ more quadrangular in A. qiiadratasinus; 

 in the smaller eyes, which do not meet in the 

 median line as in ^1. inemt.^ but are separated

 taining also a greater number of joints in the

 spines, while in A. incisa there is a single spine on the ischium and a 

 single one on the carpus.

LocaJ'ity. — Pailolo Chaiuiel. between Molokai and Maui Islands and 

 North East Approach. 



This species has been recorded from the Mediterranean (Mibie 

 Edwards); from the Adriatic, at Fayal, the Azores, and Palermo 

 (Schioedte and Meinert); from lat. 15° 40' N., long. 23° 5' 8" W. 

 (Studer). 



A single specimen was obtained by the U. S. Fish Commission 

 steamer Alhatrom which differs from those recorded as described and 

 figured by Schicedte and Meinert only in having seven spines instead 

 of six on the merus, and in not having the single spine on the 

 distal end of the propodus. Its occurrence in this locality is rather 

 remarkable.
