By Madoka Sasaki, Of the Fishery Institute, Hokkaido Imperial University. INTRODUCTION. The zoological collection made by tlie United vStates Bureau of Fisheries steamer Alhatross during her cruise in the northwestern Pacific in 1906 comprised a large number of specimens of cephalo-pods. This collection throws much light on the faunal knowledge of that region. The specimens were placed by the aforesaid bureau under the charge of Prof. S. Watase, of the. Imperial LTniversity of Tok3"o, who subsequently handed them over to the writer, who in the meantime, while a student in that university, had l)egun the mono-graphic study of cephalopods. It is a pleasure to express my thanks to Professor Watase for man}' courtesies during the progress of the work. The specimens intrusted to me have been duh' examined and are referred to sixty species belonging to twenty-nine genera. Of the sixty species eighteen are new to science. These are listed as follows: Watasella nigra. Polypus alatus. Stauroteuthis albatrossi. Polypus tenuipulvinus. Polypus gl'iber. Polypus salchrosus. Polypus ahruptus. Polypus validus. Polypus ochotensis. Rossia molliceUa. Polypus tsugarensis. Rossia hipapillata. Polypus pustulosus. Sepia carinata. Polypus spinosus. Gonatopsis octopedatus. Polypus yendoi. Crystalloteuthis heringiana. Besides these there are two new varieties, namely. Polypus macro-pus, var. minor, and Sepia Jcohiensis, var. albatrossi, which are sepa-rated from their typical forms for convenience sake, pending a more accurate study based on a greater number of specimens than is accessible to me at present. Watasella nigra in the above list is Proceedings U. S. National Museum. Vol. 57— No. 2310. 163
