THE FISHES OF THE «INGOLF>. EXPEDITIONS. 



Cyciopteriikc and Liparididw. 

 Cyclopterus (Eumicrotremus) spinosus (P'abr.). 



Of this well-known arctic species the «Ingolf»-Expedition has brought home a yonng specimen 

 captured southwest of Sukkertoppen on station 33, 67" 57' Lat. North, 55° 30' Long. West, at 35 fathoms, 

 sandy bottom, with a bottom-temperature of o°.8 C. 



The species is known from Greenland, Norway, Iceland and Spitsbergen and from some parts 

 of the east coast of America («Oceanic Ichthyology^ p. 272) and from the Bering-Sea as Cycloptents 

 cr/^/j Gthr. (Catal. Fishes III, p. 158). It is also noted in Gilbert's paper of 1896 on the north-pacific 

 fishes (p. 448) with a note that the identity of C. orbis and C. spiiipsus ought to be confirmed through 

 the confrontation of both tyjjes, while C. orbis is named without an}- further remark in Jordan and 

 Starks's t,The fishes of Puget Sound> (1895) p. 829 (Leland Stanford jun. University publication.s. 

 Proceedings of the California Academy of Sciences, Series II, vol. V). 



Liparis Reinhardti and L. micropus Gthr. 



Those, who may have consulted my little paper of 1886 on the Liparida- (vDijmphna expedition) 

 or that of Collett from 1880 («Norske Nordhavs Expedition:), will be aware, that the results arrived 

 at by us with respect to the northern Liparids were generally the following. We know i) a Liparis 

 Montagid T>o\\. and 2) a Liparis liiicatus {Li&^&c\\\\\)^ both of which make their appearance in unicoloured, 

 spotted and striated varieties, the latter type perhaps identical as species with L. htuicatiis and to be 

 considered as a minor variety or stage of evolution of the arctic form, which can attain a considerable 

 size and be furnished with a sort of small corneous tubercles or scales. 3) Liparis Fabricii Kr. (with 

 the variety L. Icprosa m.), best known from the Kara-Sea, determined after an original specimen of 

 Kroyer's species, but after my opinion not to be identified with L. tuiiicatus^ as it will be seen has 

 been done. 4) L. Reinhardti Kr., regarded by several as type for a particular genus (Careprocius), what 

 I do not find necessary, but further identified with L. gcla/iitosiis Pall, perhaps correctly, though I can 

 not take upon me the responsibility of his identification. 



The result arrived at by F. Smitt in his great and handsome work on the < Fishes of 

 Scandinavian does not differ much, but somewhat from that exposed above. He has i) a Cyclogaster 

 Montag2ii\ 2) a C. liparis^ comprising a) as <!foniia inicrops > the varieties C. lincatus^ vulgaris, barbatus 

 and fiiiiicafus^ b) as : forma megalops>-> my L. Fabricii] 3) C. gelaiinosiis Pall, o: L. (Careproctus) Rcin- 

 liardti^ to which Liparis (Careproctus) micropus Gthr. perhaps also must be reckoned as a synonym. 



I shall add a review, as short as possible, of the further and extra-Scandinavian development 

 of the Z-/j6«r/j- question. Garmau's monograph of the Discoboli (CyclopleridcF , Liparopsidce and 

 Liparididce) (Memoirs of the jMuseum of Comparative Zoology at Harvard College vol. XIV, No. 2) 

 distinguishes first a division, Cyclopteridce with the genera and species: Cyclopterus (lumpusj, Eumicro- 

 tremus (spinosus and orbis) and Cyclopteroides gyrinops. The last mentioned type from St. Paul's Island 

 (Alaska) is distinguished partly by the position of small barbels along the margin of the lower jaw 

 (cj). the figures t. XI, fig. 4 — 9; p. 37 it is said in a less definite manner: ..chin with tubular pores, or
