CEPHALOPODA OF THE HAWAIIAN ISLANDS. 
323 
the broad marginal membrane; armed with two rows of 9 to 12 hooks each, those of the ventral row in 
the main conspicuously the larger. Fixing apparatus a compact rounded group of suckers and pads 
in approximately equal numbers on the carpus. There is a compact cluster of minute suckers at the 
tip of the club. 
Color in alcohol a brownish buff, mottled with slate; a very irregular dark streak on the dorsal 
aspect marks the position of the gladius.

Distribution. — “Distribution nearly tmiversal; collected in all the oceans at numerous localities, 
equally in Arctic and tropical waters.” (Tryon 1879, p. 168.) 
Neighborhood of Laysan Island (Schauinsland; Stanford University collection). 
Material examined. — But a single Hawaiian specimen of this species has been examined. This is 
no. 2101 of the Stanford University invertebrate series and was taken off Laysan Island by Mr. Max 
Schlimmer [S. S. B. 227]. 
Remarks. — I can not find that this Laysan Island specimen exhibits any particular differences from 
the O. banksii I have seen from the Atlantic and elsewhere. So far as can be determined, there appear 
to have been ii hooks in each row on the right tentacle club and more than likely on the mutilated 
left tentacle as well. The fixing apparatus of each tentacle contains 10 suckers and an exactly equal 
number of pads, a feature which appears to be subject to great variation in this species. 
It seems clear that the original spelling of the specific name was the result of an accidental trans- 
position of type, so that the emended version seems preferable. O. banskii, O. hanski, O. banksii, and 
O. banksi are abundantly appearing variants in the extensive literature. 
This is one of the species of squid preyed upon by the Laysan albatross, and has been previously 
reported in this connection by Schauinsland .

Animals of small or very moderate dimensions. Tentacle club of young with four rows of suckers, 
the two median of which become typically modified into hooks in the adult, but in some cases only 
one of the median rows is noticeably modified, and one of the marginal rows is often very weakly devel- 
oped. Gladius with broad wings as in Loligo. 
Type. — Onykia Carriboea Lesueur 1821 (species first named); a widespread species ©riginally 
described from the West Indies.
