REVISION OF THE FISH FAMILY LIP ARID AE 67 



the species are identical and here reduce florae to the synonomy of 

 mucosas. 



LIPARIS MICRASPIDOPHORUS (Gilbert and Burke) 



Cyclogaster micraspidophorus Gilbert and Burke, 1912a, p. 71. 



Type— Male, No. 74379, U.S.N.M., Nikolski, Bering Island. Al- 

 hatross, 1906. Length 73 mm. 



Distribution. — Known only from Agattu and Bering Islands. A 

 tide-pool species. Four specimens examined. 



RelationsJiips. — L. micraspidopliorus appears to be most closely re- 

 lated to L. mucosus. It differs from the latter species in the shape of 

 the body, greater depth, more swollen cheeks, slightly larger disk, in 

 the shape of the prickles, and in the coloration. In other respects 

 the two species appear to be similar. 



Synopsis. — Dorsal 31-32; anal 25-27; pectoral 30-32; pyloric coeca 

 55-65; disk 1.7-2 in the head. Gill slit extending down in front of 

 4-5 pectoral rays. Dorsal notch deep. The connection between the 

 dorsal and the caudal equal to the skin-covered base of the latter. 

 Prickles present or absent. Body slate colored 

 above, paler below; vertical fins indistinctly 

 speclded and barred; upper half of pectoral <^ 

 speclded. In life uniform brownish red. A [^ 

 small sized species, none of our specimens reach- 

 ing a length of 100 mm. ^ figure 5.-liparis mc- 



RemarJcs. — The swollen occiput is not so no- rashdophorus. teeth 

 ticeable in the cotype, and the color varies to 

 an olive gray somewhat resembling the typical coloration of L. 

 callyodon. The lower lobe of the pectoral appears shorter than in 

 L. mucosus. 



LIPABIS LIPARIS (Linnaeua) 



Cyclopterus liparis Linnaeus, 1776, p. 414. 



Distrihution. — Coast of northern Europe. Recorded from the 

 northeastern coast of America and Japan. The possibility of this 

 species being on the American coast is discussed in the account of 

 L. atlanticus. The Japanese record, (Franz, 1910), is very doubtful 

 and will doubtless be found to be that of another species. (See 

 remarks.) 



RelationsMp . — The relationship of L. liparis with the other known 

 species is obscure. In the small number of pyloric coeca it agrees 

 with L. antarctica but the two species differ widely in other charac- 

 ters. L. liparis is readily distinguished from the other species of the 

 North Atlantic by the number of fm rays, absence of a distinct dor- 

 sal notch, the distinct connection between the dorsal and anal and 

 the caudal fin, and the small number of pyloric coeca. 



Description. — Description of a number of specimens from the 

 Cheshire coast of Ens-jand.
