Kelaupapa, Molokia, Hawaiian Islands; the type is a male, de- 

 posited in the United States National Museum and the paratypes 

 are in the private collection of Dr. S. S. Berry. 



Distribution : This species is known only from the Hawaiian 

 Islands region, where it is one of the most abundant species of the 

 cephalopod fauna, especially in shallow water and on the reefs ; it 

 has also been captured in dredge hauls ranging from the surface 

 down to 141 fathoms. Fifty-four specimens were taken by the 

 "Albatross" and ten by agents of the Leland Stanford University ; 

 these represent the only record for the species and are deposited 

 in the United States National Museum, the Leland Stanford Uni- 

 versity collection and the private collection of Dr. S. S. Berry. 

 The "Ara" specimens from Kewalo Bay add another locality for 

 the species. 



Material examined : Six specimens, taken from Kewalo Bay, 

 Honolulu, Hawaiian Islands, 2 fathoms, December 17, 1928. 



Technical description : As pointed out by Dr. Berry, in his 

 excellent description of the species, Euprymna scolopes is very 

 close to Sepiola stenodactyla Grant (= Euprymna stenodactyla 

 Grant), from Mauritius, also to E. morsei Verrill, from Japan, 

 the principal differences being in the structure of the hectocotyl- 

 ized arm. 



The largest of the "Ara" Hawaiian specimens measures 25 

 millimeters long in the median dorsal line, from the nuchal com- 

 missure to the posterior margin and is 20 millimeters wide across 

 the anterior margin. 



This pretty little squid is Sepiolid form, small and exceedingly 

 active. The body is short, thick, widely convex posteriorly, the 

 transverse diameter, measured slightly in advance of the fins, vary- 

 ing from four-fifths of the body length in large specimens to only 

 two-thirds of the length in young ones ; the thickness dorso-ven- 

 trad is 15 millimeters, measured about midway the body length. 

 The semicircular fins are widest posteriorly and are attached de- 

 cidedly obliquely, a little in advance of the middle of the body, 

 their transverse diameter being about three-fifths of the long 

 diameter; the anterior lobe is deeply incised and rounded at the 

 inner angle so that only the posterior two-thirds of the fin is at- 

 tached to the body. 



The mantle is united with the head in the nuchal region by a 

 broad commissure, 13 millimeters wide, on a specimen 20 milli-
