type (G. tricuspis) differs specifically from the Northpacific (G. pistilliger). I refer the reader to the 

 notes of Gilbert (I.e. p. 424). As I have also previously bespoken the relation between Phobetor 

 (Gymnacanthus) and the species Cot 't us claviger and C. dzcer&us, I shall further add, that these two 

 species now (Gilbert 1. c. p. 426) are cited as species of a genus Enophrys. 



Cottunculus microps Coll. 



Cot tits or Cottunculus microps is first (1875) established (Collett: Norges Fiske, med Bemserk- 

 ninger om deres Udbredelse , Tillreg til Videuskab. Selsk. Forhandl. 1874, p. 20, pi. I, fig. 3) on a very 

 young sea-scorpion, fished by Mr. O. Sars at the depth of 200 fathoms in the vicinity of Hammers- 

 fest. Afterwards den norske Nordhavs-Expedition (I.e. p. 18 — 25, pi. I, fig- 5 — 6) obtained it in 3 spe- 

 cimens, taken Northwest of Hammersfest and West of Norskoen (Spitsbergen) at depths from 191 to 

 459 fathoms (size 93 — i75 mm ); the bottom sandy or grayish blue clay, the temperature at the bottom 

 -i-0°.i a 3 .5 C. Still later it was found in the Faroe-Channel, so called, by an English expedition 

 (Giinther: Report, Challenger, p. 60, t. IX, fig. A) and by an American expedition still nearer to the 

 American side, two small specimens from a depth of 260 fathoms, 39 59' Lat. X. and 70 18' Long. W. 

 (Tarletou Bean and Brown Go ode: Report on the results of dredging , Bull. Mus. Compar. Zool. 

 1883, p. 212). From Greenland itself we have obtained 3 specimens (200 — 26o mm ) sent down bv M. 

 Miiller, inspector of the colony Sukkertoppen, and Prof. F. Smitt states ( Skandiuaviens Fiskar I, 

 p. 159), that a male of the length of i57 mm was taken on Nordenskiold's expedition on the eastcoast of 

 Greenland at 130 fathoms depth on clay bottom and at 65 30' Long. North. The most northern point 

 where this sea-scorpion of the cold and deep sea is known is 8o : Lat. Xorth (Spitsbergen), the most 

 southern on the European side is the Trondhjemsfjord (6372); according to the statement of F. Smitt 

 it is there taken in rather numerous specimens at depths from 100 — 200 fathoms. After a note bv 

 T. Bean (Xotice of the remarkable marine fauna occupying the outer banks of the southern coast of 

 New England, Xr. 2; American Journal of Science, October 1881, p. 296) it is taken at 7 stations at 

 the depth of 310 — 396 fathoms on the banks off the southcoast of Xew England. Giinther (I.e.) also 

 states, that several specimens are known from the southcoast of Xew England at depths from 238 to 

 372 fathoms. Compare also Oceanic Ichthyology p. 269, fig. 257 and 261 a, b. 



This species is figured by Collett at the places cited in Xorges Fiske and in den norske 

 Nordhavs Expedition , by Giinther in the deep-sea fishes of the Challenger (I.e.), and by F. Smitt 

 ( Skandinaviens Fiskar , I, p. 158, fig. 45), further in Oceanic Ichthyology pi. 1. As it is also described 

 by the said authors, by Lilljeborg and by Jordan and Gilbert (Synopsis of the fishes of Xorth 

 America 1882, p. 688) I may limit myself to an enumeration of the Ingolfian localities and to the 

 addition of a few descriptive notes. 



The skin is densely rough every where on the head, body and tail, weakest on the bellv, from 

 small round asperities; at some places they are grouped together in small heaps and may be continued 

 on the dorsal rays -- more sparsely on the pectorals. The iuterorbital space is rather large. Behind 

 the eyes is found an arc of 4 coniform knobs; somewhat more behind, on the occiput, are two and at 

 both sides in a line with the upper end of the branchial cleft one or two smaller knobs with some more
