That Ocythoe, at least, is a member the genera to be represented in of our fauna, suspected, partly because of a specimen which assemblage in its nearest being the was I have long exhibited in one of the Los Angeles curio stores some years since, but ignorantly held at so inflated a figure, that the university it could not be obtained even for one of museums, and another without be from Southern California, which State University at Berkeley me A is now label, but thought to in the collection of the further bit of evidence, which to savors strongly of this same animal, lies in a paragraph by the Dr C F Holder with regard to a specimen obtained by him He at Avalon (Scientific American, October 16, 1909, p 283) late wrote "It is given argonaut so in is a in all the all species I or nine inches, and of this species having As Its textbooks, I believe, that the male of the This cannot be minute animal hardly an Inch long is have Is a male which has a radiant spread of eight The male and might readily be taken for an octopus, as large as the female large, habits." male Argonauta answering such a description as this would be a sheer absurdity, the lines quoted served at first to occasion me no little perplexity Surely, however, the suggestion that Holder's specimen was a female Ocythoe and not an Argouauta at all, seems a not only possible, but plausible These cases are fauna but, in all strong Indications that Ocythoe belongs to our view of the obvious uncertainty attending each, no formal record of the fact has yet found Its way into print Pomona A College, Claremont, California very large and finely preserved female, recently sent Prof William A Hilton, now settles the me by matter without question This specimen (S S B 453) was obtained from near Avalon, Santa Catalina Island, California, in the summer of 1915, by Mr W F Hamilton Unfortunately I have no comparative material from other regions available, so that with only the aid of such figures and printed descriptions as are at hand, the specimen cannot be distinguished from the Mediterranean O tuberculata, described and As named by Rafinesque just over one hundred years ago tuberculata happens to be the only species of the genus enjoy- ing general recognition, and as sibility it is a pelagic creature with the pos- of very wide dissemination, the identification seems never- theless to be reasonably certain, the areas it is quate material though it should be admitted that alleged to inhabit are so widely separated that ade- may later reveal differences which will be thought worthy of recognition In addition to Mediterranean localities the species has been reported from Vineyard Sound, Massachusetts, from the West Indies, and from Japan The sexes in this genus, as in the related Argonauta and Tremoctopus, show such extreme dimorphism, that the description of one applies in scarcely a single particular to the other Ocythoe, however, is The female very easily distinguished from other cephalo- pods by the large Octopus-like body, the ventral surface of which is very curiously ornamented with numerous conspicuous cartilaginous tubercles, connected by radiating ridges The enormous and powerful funnel is also noteworthy The more important measurements of the present specimen are appended below, many of them necessarily more or less estimated MEASUREMENTS Total length
