500 MISCELLANEA. 



length was 4-ft. i-in. With the kind assistance of Mr. C. T. 

 Regan, of the British Museum, the fish was identified as an 

 example of an arctic species of cat-fish, Anarrhichas latifrons, 

 Steenstrup and Hallgrimossn {■=. A. denticulatus, Kroyer-''). 

 This species is known chiefly from within the Arctic Circle, 

 and it had never previously been recorded from British waters. 

 Mr. Thomson has ascertained for us that the present example 

 was caught 15 miles east-north-east from Tynemouth bar, on 

 50 fathoms of water (s.s. Nellie, skipper R. A. Lang). 



The most important characteristic of this species from a 

 systematic point of view is the size and arrangement of the 

 teeth. These are much smaller than in A. hipus, and the 

 vomerine teeth in the middle of the roof of the mouth do not 

 extend so far back as the palatine series at the sides ; in 

 A. biptis exactly the opposite arrangement is found. A cast 

 of the entire fish was taken, and the head is preserved at the 

 museum. — E. L. Gill. 



Fnsiis islandicus^ a correction. — In the list of Mollusca 

 taken with a dredge in 1901 (see " Report on Dredging and 

 other Marine Research off the North-East Coast of England 

 in 1901," by G. S. Brady, M.D., F.R.S., etc., Natural History 

 Trarisactions of Northumberland, Durham, and Newcastle- 

 upon-Tyne, vol. 14, page 93), I much regret having recorded 

 Fustis islandiciis, Chem., from this coast. The specimens 

 turned out to be large Fusus gracilis, Da Costa. — Af. V. 

 Lebovr. 



Larval Trematodes : further notes and references. — In my 

 paper on larval Trematodes in the present number I find I 

 was mistaken in stating with regard to Monostoimtm flavvm 

 that the small suckers at the posterior angles of the body had 

 apparently not before been noticed. They were noticed by 

 (Nitzsch in his Cercaria ephemera, and Looss (" Recherches 

 sur la Faune Parasijtaire de I'Egypte," 1896, p. 194) gives a 

 detailed account"" of mese structures in Cercaria imbricata.
