determination, which have received attention from one of us in a previous number 

 of these Transactions.* 



L. vulgaris is not included by Dr. Gitnther in the Challenger Monograph on 

 Deep-sea fishes, although it had previously been recorded by the same author 

 among the species taken by the " Porcupine " at 180 fathoms in the Faroe Channel. 

 Beyond this, it is only known as a littoral form, but it is interesting to note that 

 it has been taken at a depth of 64 fathoms ofi the Mull of Cantyre.t

 Genus Careloplius, Krbyer. 

 Carelophus ascanii, Walbaum. (Deep-sea.)

 Chirolophus galerita, . . . Smitt, "Hist. Skand. Fish.," ed. ii., p. 218. 



This species was not met during the survey, and has only been recorded within 

 the Irish area from shallow water. Specimens have been taken at 180 fathoms in 

 the Faroe Channel (Giuither) at 140 fathoms in Trondjheim Fjord (Strom.), while 

 the maximum depth at which it has been known to occur in Norwegian waters 

 appears to be 182 fathoms (Smitt). 



Fam.— TRACHYPTERIDiE. 



Genus Trachypterus, Gouan. 



Trachypterus arcticus, Briinner. The Northern Deal-fish. (Deep-sea.) 



Trachypterus arcticus, Day(?), " Zool.," February, 1875, p. 4343. 



The Deal-fishes are without doubt abysmal in their normal habitat, although, 

 as it happens, only a single example has actually been taken in deep-water (c/. 

 Giinther, Chall. xxii. pp. 71—72). The species under consideration is represented 

 in Irish records by a single example washed ashore at Bundoran.
