Body smooth, rather eh)ngate. somewhat pointed behind, 

 very delicate, semigelatinous, and iridescent, especially about 

 the eyes and the base of the arms. Funnel long, extending past 

 the rounded, prominent eyes. Arms delicate, slender, attenuate, 

 connected at the base by a tenuous umbrella of about equal 

 extent all around ; order of length 1, 2, 3, 4. Suckers small but 

 elevated, clearly in two rows except at the base where they show 

 a tendency to remain in the median line. 



Chromatophores small, distinc^t and numerous, Avith two rows 

 of larger irregular ones along the outer surfaces of the arms. 



From Univ. Calif. Sta. XXXVa, off Catalina Harbor, Santa

This great squid has frecpiently been reported from Monterey 

 Bay, the Santa Barbara Islands, and other points on the coast, 

 hut never in such a fashion as to establish its identity satisfac- 

 torily beyond reasonable d(>ul)t. It is thei'efore noteworthy that 

 1h(^ Tniversity possesses a beautifully preserved, vuidoubted, 

 adult individual from Monterey Bay, thus assuriiig this interest- 

 ing species an established place in our fauua. 



The species is very readily recognized by its size; the atten- 

 uate arms having the very numerous strongly-toothed suckers 

 much reduced on the distal part; and the characteristic trabe- 

 culae, which appear as stout outgrowths extending past even the 

 broad- swimming web of the third arms except for a space on the 

 ventral margin (pi. 21, fig. 3) of the latter. 



The more proximal suckers on the sessile arms (pi. 21, fig. 5) 

 are very large, oblique, hood-shaped, with short, robust pedicels 

 and very conspicuous horny rings, armed with about 19-20 sharp, 

 curved, conical teeth, the upper median and two lateral teeth 

 notably the largest (text fig. 1). Coincident with the extreme 

 attenuation undergone by the distal half of the arms, their 

 suckers suffer a striking modification, suddenly becoming greatly 

 reduced in size, as well as deeper, their bases more elevated, and 

 pedicels more elongate and slender (pi. 21, figs. 4, 6).
