14 THE DISCOBOLI. 



established the subfamily Ci/dojiterhn, an apparent equivalent of the family 

 itself. Lcs Chondrosies Ptero-podes of Dumeril, 1856, were made up of 

 Lepadogaster, Cyclogaster, Gobiesox, Cyclopterus, Chironeotes, Lopliius, 

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

 within it the families Cy dopier oidd, with the single genus Cyclopterus, and 

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

 including Liparis. Gunther, 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 (Jydopteroidi^. His* subfamily names were Cyclop- 

 terinfB and Liparinse ; of the latter he made Liparidinae in 1864, and 

 LiparididiB in 1872, on raising it to family rank. In Gill's Gohiesocoidca, 

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

 The Ci/dopteroidea of Gill, 1873, contained only the C^^clopteridce and the 

 Liparididce, the Discoboli of Gunther. 



In the present revision the family Cyclopteridae is restricted to the 

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

 second being somewhat doubtful. Cydoptcrus 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. Cijdopteroides 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. 

 Cydopten'chthys was characterized by Steindachner, 1881, from what he 

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

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

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

 manuscript. 



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

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

 he gave the name Discoholes. 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. MUller, 1843, contained the following : " die
