LIPARTS GREBNITZKII (Schmidt) 



Neoliparis grebnitzkii Schmidt, 1904a, p. 165, pi. 6, fig. 4. 



Type. — Female, No. 8855, museum of St. Petersburg, Bering Island. 

 Grebnitzki. Length 83 mm. 



Distribution. — Known only from Bering Island. No specimens 

 examined. 



Relationsliip. — Schmidt (1904a) considers this species to be most 

 closely related to L. rutteri. I can not agree with him and believe L. 

 grebnitzkii to be most closely related to L. caUyodon and possibly 

 identical with it. I am unable to detect any important differences 

 between the two species. 



Synopsis. — Taken from the original description. Dorsal 32; anal 

 27; pectoral 29; caudal 10; pyloric coeca about 30; eye 6.6; snout 

 3.1; disk 2.2. Gill slit above the pectoral. Color tawny; head and 

 back brown; fins grayish; pectoral yellowish, without spots. 



LIPARIS MUCOSUS (Ayers) 



Liparis mucosus Ayres, 1855, vol. 1, p. 24; 1873, vol. 1, p. 22. — Garman, 1892, 

 p. 52, pi. 5, figs. 1-5 (part). — Jordan and Starks, 1895, ser. 2, vol. 5, p. 832,

Neoliparis florae Jordan and Starks, 1895, ser. 2, vol. 5, p. 830, pi. 96. — Jordan 

 and Evermann, 1898, p. 2111, fig. 762. 



Type. — Destroyed. San Francisco. 



Distribution. — Northwest coast of America from Pacific Grove, 

 Calif., to Kodiak Island, Alaska. A tide-pool and shallow-water 

 species. Twelve specimens examined. 



Relationships.' — L. mucosus is most closely related to a twin species, L. 

 micrasjndopliorus, from the Aleutian Islands. It can be distinguished 

 from the latter species by the coloration and the shape of the head and 

 body. In addition to the above differences the disk is slightly smaller 

 in L. mucosus. The coloration of the body and peritoneum, the shape 

 of the head and body, and the size of the gill slit and disk readily 

 distinguish this species from all other species with an equal number of 

 fin rays inhabiting the same regions. 



Synopsis. — Dorsal 31-33; anal 25-27; pectoral 30-33 ; pyloric coeca 

 48?-70. Disk 2.1-2.4, in the head. Gill slit extending down in front 

 of from 1 to 6 pectoral rays, usually in front of more than 3 rays. 

 Dorsal notch distinct, the anterior dorsal fin sharply pointed. Dorsal 

 and anal connections with the caudal very short, little, or not at all, 

 extending beyond the skin-covered base of the latter. Prickles present 

 or absent. Head and anterior part of body appearing depressed; 

 greatest depth of body usually at the end of the first third of the second 

 dorsal fin. Color dark brown to light yellowish brown, paler below, 

 sometimes with longitudinal wavy stripes; fins colored as the body or 

 faintly barred; first dorsal sometimes a dark blotch. A small- 

 sized species, reachmg a length of 125 mm.
