258 BULLETIN OF THE BUREAU OF FISHERIES. 



collections include one species (Onychoteuthis banksii) which was not taken by the 

 Albatross. 



In addition to the above there have constantly been available the collections of 

 cephalopods made by the Albatross during the Alaska salmon investigations of 1903 

 and the dredgings off the California coast in 1904, together with the considerable series 

 of west American and Japanese specimens owned by Stanford University. Although 

 all of these have already been made the subject of reports (Berry 1912a, 1912b), their 

 value for comparative study in the present consideration has been inestimable. 



The type specimens of new species together with certain others have already been 

 assigned catalogue numbers by the authorities of the National Museum, and such numbers 

 are carefully cited in the proper paragraphs of the following pages. In referring to the 

 Stanford University material, I have for the sake of brevity adopted the University 

 initials — L. S. J. U. — immediately succeeded by a catalogue number which has reference 

 to the invertebrate series in the University collections. 



As will be seen, the material thus utilized lacks only Polypus hawaiiensis, Sym- 

 plectoteuthis oualaniensis , and the clearly erroneous Loligo gahi and Polypus jontanianus, 

 to embrace all the species known or reported from the islands, the great bulk of the records 

 being nevertheless entirely new. The total number of specimens which I have personally 

 examined is 210. These are distributed among 24 genera and include somewhat more 

 than 29 species, only 4 of which have been previously recorded from the region. Some 

 15 of these species it has been found advisable to describe as new, and it is quite probable 

 that several of the 10 or more forms represented by specimens too immature or too poorly 

 preserved for accurate determination belong to species not yet described. 



The Albatross collection has already formed the basis of two brief preliminary 

 papers (Berry 1909, 1913), in which the majority of the new species were tersely described 

 and in the first of which a provisional check list of all the species was also given. 



HISTORICAL SURVEY. 



With the exception of the two papers which have been just referred to as preliminary 

 to the present report, no work specially devoted to Hawaiian Cephalopoda has ever been 

 published. Even the scattered references contained in volumes of wider scope are not 

 numerous and only to be found by dint of the most exhaustive searching. Despite 

 its brevity, therefore, the following cursory survey of the literature is thought to be 

 practically complete. 



I have been unable to determine to what author belongs the honor of first bringing 

 a Hawaiian member of our group to the public notice, since Gould in America and 

 Souleyet in France both published in the same year. The latter author, reporting in 

 1852 on the mollusks taken during the voyage of the Bonite, describes only a single species 

 from the islands, the Octopus hawaiiensis , a form which would naturally be expected 

 to be abundant, but which has not been recognized with any certainty since. 



In the magnificent memoir by Gould (1852) on the Mollusca of the Wilkes exploring 

 expedition, two Hawaiian species are described for the first time, both of them common 

 littoral forms, namely, Octopus ornalus Gould, and Scpioteuthis arctipinnis Gould.
