The name mcfjacepJiahis, since it bas been published along with a diag- 

 nosis of its leading points of difference from C. pugettensis, must, I pre- 

 sume, be retained, instead of a more expressive term which might be 

 drawn from the form of the dorsal fins. 



C. megacephaliis is tolerably abundant in moderately deep water out- 

 side the Bay of San Francisco. Specimens numbered 27185 are in the 

 National Museum. 



DES4.1IUPTIONS OF NEW FISHES FROM ALASKA AK» SIUERIA. 



BY TAKliETO]^ M. BEAN. 



Most of tlie species here described were obtained for the United States 

 National Museum during the summer of 1880, through the assistance of 

 the United States Coast Survey schooner Yukon, whose party the writer 

 was permitted to accompany for the purpose of making collections, more 

 l)articularly of fishes and fishery statistics, in Alaska. It would have 

 been difficult, if not impossible, to secure so valuable a collection of the 

 fishes in any other way, the Yukon having called at numerous ports 

 along the major portion of the Alaskan coast as well as at Plover Bay, 

 Siberia, where several species not elsewhere found w^ere taken. The 

 whole number of species taken is above 80, and it is due to the Super- 

 intendent of the United States Coast Survey and to Mr. W. H Dall to 

 say that their generous help has made this result possible. 



In this article, which is simply preliminary to a detailed account, short 

 notices only are given of fishes which are to be more fully describe<l 

 hereafter. 



Lyccdes coccineus n. s. 



Museum Catalogue number 27748 ; collector's number (1712). 



Big Diomede Island, September 10, 1880. 



Br. VI; D. including half of caudal 87; A. including half of caudal 

 69 ; P. 18 ; Y. 3. Posterior two-thirds of tail covered with scales which 

 are not in contact. Fins and all parts of the body and head scaleless. 



The total length of the typical specimen in its fresh state was 19.7 

 inches (484 millimeters). In its present state of preservation it has 

 shrunk to 475 millimeters. 



The species resembles L. mucosns Rich., but may be readily distin- 

 guished by its more extensive squamation, shorter and deeper head, 

 stouter tail, more advanced position of veiitrals and vent, and by its 

 coloration; L. miicosus, too, has a lateral line consisting of rounded open 

 pores, while L. coccineus has sim])ly a few faint, short linear scratches 

 which are almost iju perceptible to the eye. These traces are seen only 

 on that portion of the skin which has scales. 



The greatest height of the body is a little less than half the length of 

 the head, which constitutes nearly' one-fourth of the total length. The 

 p( ctoral is twice as long as the intermaxillary and terminates at a dis-
