310 REPORT OF A CRUISE IN H.M.S. 



British species ; it comes nearest to Rata circularis and R. miraletus 

 (from tlie Mediterranean), but shows differences in the scutellation 

 form o£ the body, and ornamental colouring. But it would be 

 hazardous to offer a more definite opinion, as we know very little 

 about the amount of variation and of the changes with growth and 

 locality in rays/^ 



All the specimens taken were apparently young. 



Teleostei. — Acanthopterygii. 



ScORPJiNA DACTYLOPTERA, De la RocJw. 



Several specimens in 200 and 217 fath. This species was also 

 taken by Mr. Green, before whose expedition it was unknown to 

 British fauna. 



LOPHIUS PISCATORIUS, Liwi. 



A single large specimen at Station 4, 200 fath. The angler, 

 according to Brown Goode, is known to descend to considerable 

 depths. 



Callionymus LYRA, Linn. 



Many specimens, Stations 7 and 8, 70 fath. 



Anacanthini. 



Gadus argenteus, Guich. 



Two specimens at Station 4, 217 fath. This species was first 

 found in the Mediterranean, and has only once been taken since, by 

 the " Porcupine " in 1869, very close to the station at which I ob- 

 tained it. (See Giinther, Ann. Mag. Nat. Hist., xiii, 1874, p. 138.) 



Phycis Aldrichii, n. sp. 



Two specimens of this genus were obtained at Station 1, from a 

 depth of 200 fath. After careful examination (they are unfortu- 

 nately a good deal damaged) I cannot identify them with any 

 described species, and therefore propose to name it, provisionally, 

 Phycis Aldrichii, in honour of my host, Capt. Aldrich. This form 

 is very closely allied to P. americanus, Schn. (with which it may 

 prove to be identical), differing from it chiefly in the first dorsal, 

 the anterior rays of which are not elongated in P. Aldrichii. 



The following is the description of the species :
