REVISION OF THE FISH FAMILY LIPARIDAE 79 



and the sixth and seventh rays found to be shorter than the preceding 

 rays. Two of these specimens showed pale stripes extending back- 

 ward from the snout above and below the eye to the caudal. The 

 remainder of these specimens were speckled with brown and the caudal 

 broadly barred. Fully half the specimens No. 21314 S.U.Z.M., 

 have the dorsal notch evident without dissection.

Liparis agassizii, Jordan and Evermann, 1898, p. 2721, fig. 765 (part) .^Ever- 

 MANN and GoLDSBOROUGH, 1907, p. 333, fig. 101, (part). 



Type.— Msxle, No. 24047, U.S.N.M.; St. Paul Island, Bermg Sea. 

 Length 68 mm. 



Distribution. — St. Paul Island, Bering Sea, and coast of Siberia. 

 Four specimens examined. 



Relationship. — In the region extending from Washington north- 

 ward through Bering Sea and southward through the Okhotsk and 

 Japan Seas is a series of six closely related species of Liparis. Of 

 these L. dennyi is found from the coast of Washington to the Gulf of 

 Alaska, L. gihhus and L. cyclostigma in Bering Sea, L. ochotensis and 

 L. rJiodosoma in the Okhotsk Sea, and L. ingens in the Japan Sea. 



The two Bering Sea species are not readily separated. I have 

 recognized the two species as distinct. However, the slight differences 

 between the types may be due to age. The three Japanese species 

 appear to have a larger number of dorsal and anal rays and prickles. 



Synopsis. — Dorsal 42-44; anal 35-36; pectoral 37-38; pyloric coeca 

 45. Posterior nostril apparently without a fingerlike projection in 

 front. Upper jaw projecting. Eye moderate, 4 to 5.5 in head. 

 Disk 2-2.3 in head. GiU slit extending down in front of 14 pectoral 

 rays. Dorsal unnotched. Dorsal connected to caudal for nearly 

 one-half the length of the latter. No prickles.

Liparis cyclostigma Gilbert, 1896, p. 446, (part). 



Cyclogaster cyclostigma Gilbert and Burke, 1912a, p. 73, fig. 18. 



Type.— Male, No. 48621, U.S.N.M., vicinity of Bristol Bay, 

 Bering Sea, Albatross Station 3252; depth 295 fathoms. 



Distribution.— Bering Sea, Albatross Stations, 3252, 4777, 4779, 

 4789, 4795, 4796 ; depth 43 to 295 fathoms. Six specimens examined. 



Relationships. — L. cyclostigma closely resembles L. gibbus. (See 

 description of latter species.) 



Synopsis. — Dorsal 40-44; anal 33-35; pectoral 39-43. Posterior 

 nostril without projection. Disk 2.3 in head. Gill slit extending 

 down in front of 12 to 14 pectoral rays. Dorsal connected to caudal 

 for nearly one-half the length of the latter. No prickles. A large 

 species reaching a length of 357 mm.
