deeper above and bear about 20 teeth, which are very long, slender and acute on the upper margin 
(obtuse and reduced below) and occur in alternation with minute bluntish denticles; none of the teeth 
in these suckers notably larger than the others. I can not make out any pads or specially differentiated 
suckers which could be construed as constituting a fixing apparatus.

Remarks. — This is one of the commonest Hawaiian squids and probably a species of considerable 
economic value in its food relations to many sea birds and the larger fishes. Because it is so abundant 
and characteristic a member of the fauna of this region, I have little doubt that the specimens listed 
by Schauinsland and more recently Pfeffer from Laysan Island as O. sloanei are the same form. The 
true O. sloanei, however, appears to be a somewhat different creature, as Gray expressly states that the 
homy rings of the suckers have the “higher side with regular acute teeth, lower smooth” (italics mine), 
while the remainder of Gray’s diagnosis is so sadly incomplete or even silent regarding what should 
prove to be featmes of the highest importance, that there seems every likelihood that other even more 
striking differences will eventually appear. O. hawaiiensis is imdeniably a near relative of the Japanese 
O. pacijicus Steenstmp, considered by many to be a synonym of O. sloanei (cf. Berry 1912b, p. 436-437), 
but the specimens before me differ consistently in their more rapidly tapering body, slightly shorter 
fins, much larger and wider head, very much fewer and larger suckers on the sessile arms (especially
