14 THE DISCOBOLI. 



established the subfamily Cychpterim, an apparent equivalent of the family 

 itself. Lcs Chondrostes Pteropodes of Dumeril, 1856, were made up of 

 Lepadogaster, Cyclogaster, Gobiesox, Cyclopterus, Chironectes, Lophius, 

 and Malthea. Bleeker, 1859, adopted the order Cyclopteri, and placed 

 within it the families Cyclopleroidei, with the single genus Cyclopterus, and 

 the Gdbiesocioidei, with Gobiesox and its properly related allies, and also 

 including Liparis. Giinther, 1861, made Liparis the typical genus of his 

 subfamily Liparidina, which with the Cyclopterina constituted the family 

 Discoboli. Gill, 1861, did not differ in regard to the contents of the 

 family, but named it Cychpteroidce. His subfamily names were Cyclop- 

 terinae and Liparinse ; of the latter he made Liparidina? in 1864, and 

 Liparididae in 1872, on raising it to family rank. In Gill's Gobiesocoidea, 

 1872, he included the Gobiesocidae, the Liparididae, and the Cyclopteridae. 

 The Cyclopteroidea of Gill, 1873, contained only the Cyclopterida? and the 

 Liparididae, the Discoboli of Giinther. 



In the present revision the family Cyclopteridas is restricted to the 

 genera Cyclopterus, Eumicrotremus, and Cyclopteroides, the rank of the 

 second being somewhat doubtful. Cyclopterus of Linne, 1735, was estab- 

 lished on the common Lump of the North Atlantic. Eumicrotremus of 

 Gill, 1864, was based on C spinosus Fabr., an Arctic and deep-sea form. 

 C. orbis Gthr. belongs with this species; it is obtained in the North 

 Pacific. Cyclopteroides is a new genus, characterized below, from the 

 North Pacific. 



Liparopsidce. — This family is here arranged for a couple of genera, at 

 present known from the North Pacific, Cyclopterichthys and Liparops. 

 Cycloptcrichlhjs was characterized by Steindachner, 1881, from what he 

 took to be a new species, C. glaber (not C. glaber from Steller, 1831), but 

 which was identified by others with C ventricosus of Pallas, 1769. Liparops 

 is based on Cyclopterus Stelleri of Pallas, 1831, the C glaber of Steller's 

 manuscript. 



Discoboli. — Cuvier, 1817, brought together Lepadogaster, Gobiesox, 

 Cyclopterus, Liparis, Echeneis, and Ophicephalus in a group to which 

 he gave the name Discoboles. At the hand of Latreille, 1825, the name 

 was written Discobola, and at that of Griffith, 1834, it became Discoboli. 

 The division Cyclopodi of J. Midler, 1843, contained the following: "die
