apparently never present. Color variable, usually distinct in the 

 presence of a white bar across the base of the caudal and the posterior 

 margin of the dorsal and anal fins. A small species, the largest speci- 

 men being 63 mm. in length. 



Remarks. — The elevated dorsal is not always present in the male, 

 for one of our specimens, a male from Agattu, has a very low dorsal. 

 None of the female specimens exammed have an elevated dorsal. 

 Four of the specimens exhibit the striped color pattern; of these 1 is 

 from Karluk, 2 from Loring, and 1 from Station 4205, Admiralty 

 Inlet. Apparently no morphological differences can be correlated 

 with the striped color pattern. The specimen from Station 4205 is 

 the only one taken in the dredge. It differs from the others in the 

 paler coloration. In addition to the stripes — the color of this speci- 

 men is as follows: Light ashy brown, darker posteriorly; margin of 

 dorsal and anal dusky; caudal finely crossbarred. The white bar at 

 the base of the caudal apparently is distinctive of the species though 

 absent in one specimen and faint in others. 



LIPARIS CURILENSIS (Gilbert and Burke) 



Cyclogaster curilensis Gilbert and Burke, 19125, p. 353. 



r?/2?6.— Female, No. 73326, U.S.N.M. Simushir Island, Japan. 

 Albatross, 1906. Length 110 mm. 



Distribution. — Known only from the type locality. Thirty-two 

 specimens examined. 



RelationsM'p. — In general appearance and in coloration this species 

 resembles L. callyodon. It can be distinguished from the latter by 

 the much larger ventral disk. In the size of the disk L. curilensis 

 agrees with L. rutteri. It is readily distinguished from the latter by 

 the coloration and number of pj'loric coeca. The coloration does 

 not differ materially from that of L. callyodon though usually the cross 

 bars are much more pronounced. None of our specimens exhibited 

 the spotted coloration sometimes shown by L. callyodon. 



Synopsis.— Dorsal 34-35; anal 26-27; pectoral 29-30; pyloric co- 

 eca in one specimen 65. Disk large, 1.5-2 in head. Gill slit above 

 the pectoral or extending down in front of the upper pectoral ray. 

 Dorsal notched. Dorsal and anal barely or not at all connected with 

 the caudal. Coloration as in L. callyodon.
