Holt and Calderwood — Report on the Rarer Fishes. 449 



Genus Motella, Cuvier. 

 Motella cimbria, Linnaeus. (Deep-sea.) 



Onus cimhrius, Goode and Beau, " Proc. U. S, Nat. Mus.," iii., 



1881, p. 476; "Bull. Mus. Comp. ZooL," x., 

 1883, p. 207. 



M. cimbria, Schaeff, " Irish Naturalist," 1893, p. 176. 



This rockling was not known from Irish waters at the time of the Survey, but, 

 in suggesting it as the possible parent of a Motella-like ovum and larva, doubts 

 were expressed by one of us* as to how far its absence from the Irish list could, in 

 the existing stage of our knowledge of the Irish fish-fauna, be held to invalidate 

 the suggestion. The parentage of the ovum remains in doubt, but the adult has 

 since been added to the Irish list by Dr. ScharfP. It is only known in the old 

 hemisphei'e as a littoral form, but has been recorded from the American coast at 

 178 fathoms. 



Motella tricirrata, Bloch. (Deep-sea.) 



M. tricirrata, Vaillant, "Exp. Sci. Trav. Talism. Poiss.," p. 285. 



The three-bearded rockling was taken in the French dredging expedition at a 

 maximum depth of 346 fathoms off the N.W. coast of Africa. "Mackerel- 

 midges," apparently belonging to this species, were frequently taken at the 

 surface during the Survey, but no adult forms were met with at any depth. 



Genus Brosmius, Cuvier. 



Brosmius brosme, Midler. The Tusk or Torsk. (Deep-sea.) 



B. brosme, Gunthee, " Proc. Roy. Soc. Edin.," 1882, p. 680. 



,, LiLLJEBOEG, "Sver. 0. Norg. Fisk," ii., p. 202. 



„ Smitt, "Hist. Skand. Fish.," ed. 2, p. 562. 



Several tusk were taken during the Survey at 250 fathoms off the coast of 

 Mayo. The species is very little known in Irish waters, although it appears to 

 occur regularly off Dingle Bay. Mr. Green, who is our informant in this respect, 

 tells us that the fish is known in that district as the " Cat-ling." It is evident 

 that the fishes alluded to by Day as taken " far out at sea off the Gal way coast" 

 belong to this species, and not, as was supposed, to Anarrhichas lupus.
