476 THE FUR SEALS OP THE PRIBILOF ISLANDS. 



species are included among our specimens. Dr. Bean records this species from Una- 

 laska, Adakh, Amchitka, St. Michael, and Plover Bay. Stejneger and Grebnitzki 

 found it on Bering and Medni islands. 



144. Neoliparis oyolopus Giinther. 



Eecorded by Dr. Gilbert from Bristol Bay. It ranges southward to Vancouver 

 Island. 



145. Iiiparis pulchellus Ayres. 



Recorded by Dr. Gilbert from Bristol Bay, whence it ranges southward to San 

 Francisco. Dr. Beau notes it from Unalaska and Kadiak. 



146. Liparis cyclostigma Gilbert. (Plate LXXIII.) 

 One specimen known, from near Unalaska. 



147. Liparis agassizii (Putnam). 



Originally described from Sakhalin; generally common in the north of Bering 

 Sea, south to Bristol Bay, whence it wns recorded by Dr. Gilbert. Dr. Bean records 

 it (as Liparis gibbus) from Unalaska and Petropaulski. 



148. Liparis herachelinus Scofleld. (Plate LXXIV.) 



Northern parts of Bering Sea; described from Herschel Island. 



The specimens from Bering Island collected by Grebnitzki, recorded aS Liparis 

 tunicata by Bean and Bean, Proc. U. S. Nat. Mus. 1896, 243, probably belong to this 

 species. 



CRYSTALLICHTHYS Jordan and Gilbert. New genus. 



Closely allied to Liparis, from which it differs chiefly in the single nostril. A 

 single dorsal fln ; a well developed sucking disk ; wide bands of teeth, many of which are 

 trilobate near tip; an inferior mouth, much overhung by the produced conical snout; 

 a single nostril, corresponding to. the anterior nostril of other Liparids, the posterior 

 opening being wholly wanting. The typical species, C. miraUlis, differs from all 

 known species of Liparis except L. cyclostigma in its large size, compressed form, and 

 translucent gelatinous texture. 



149. CrystaUichthys mirabilis .lordan and Gilbert, new species. (Plates LXXV, LXXVI.) 



A large species, soft and gelatinous in texture, the color translucent grayish or 

 purplish, marked on back with many large light circles, which were probably deep red 

 or crimson in life. 



Type, a specimen 330 mm. long, from station 3643, off southeast coast of Kam- 

 chatka, at a depth of 100 fathoms. 



Head 4 in length; depth 2J; snout 2\ in head; eye 3J in snout. Width of mouth 

 one-half length of head. Length of gill slit, one-half snout, equaling distance from 

 front of eye to front of nostril tube; P., 33. 



Head and body compressed, especially along upper profile, which descends in a 

 gentle, nearly even curve to tip of snout. Lower profile less curved, nearly straight 

 and horizontal on anterior third of body. Snout conical, tapering to a sharp tip, its 

 lower profile nearly horizontal, protruding beyond the mouth for a distance (measured 

 axially) equaling two-fifths its length. Mandibular symphysis vertically below nostril 

 tube. Upper jaw strongly arched anteriorly, the mandible much shorter, nearly 

 transverse in position. When the mouth is closed there is exposed the entire width 

 of the thick upper lip, and the anterior portion of the band of fringes which precedes
