Remarks. — This species differs from P. antadicus Regan, the only other species 

 described from Antarctica, in the following characters: The eye is slightly smaller 

 and the snout longer; the pores on the head are more numerous, occurring on the 

 snout, none being so figured in P. antarcticus. The shape of the vertical fins 

 is difi'erent, while the caudal is partly enclosed by the dorsal and anal membranes; 

 the vent occupies a forward position, behind the lower portion of the pectoral, as 

 is usual in these forms, while Regan's statement that these lower portions reach 

 the vent would indicate that the latter is placed quite near the origin of the anal 

 fin, and therefore, in a position normal to the majority of fishes. P. wildi appears 

 to be more nearly allied to the northern P. bathyhii CoUett, the type of the genus. 



Addendum. — P. terrae-novae Regan differs more from P. antarctica than does 

 P. wildi, possessing fewer fin rays, and having no elongate lower rays in the pec- 

 toral. Three species are now known from the Antarctic.

Genus LIPARISCUS Gilbert 



Lipariscus Gilbert, 1915, p. 358. 



Allied to Paraliparis and Nedoliparis, agreeing in habit with the 

 former, and with the latter in having but five branchiostegal rays, 

 while all other genera in this family have six. 



FiGUEE 110.— Lipariscus nanus. Type 



No trace of a ventral disk. Vent posterior in position, lying in the 

 area between the lower pectoral lobes. Pectoral fin greatly reduced 

 but the two lobes connected, not separate and distinct as in Nedol- 

 iparis. Teeth simple, in narrow bands. Branchiostegals 5. GUI 

 slit narrow, confined to the suprapectoral region. 



Genotype. — Lipariscus nanus Gilbert. 



LIPARISCUS NANUS Gilbert

Type.— C&t. No. 75817, U.S.N.M.; 47 mm. long, from Station 

 4461, Monterey Bay 285 to 357 fathoms. 



One paratype from the type locality, and three others from Station 

 4468, Monterey Bay, 32 to 309 fashoms. 



BIBLIOGRAPHY AND LITERATURE 



This bibhography is designed to include the most important works 

 relating to the Liparidae. It is not the result of an attempt to 

 include all the lists and discussions of the species described. It is 

 reasonably complete concerning recent descriptions and notes. For 

 a more complete list of older publications see Garman, 1892.
