I am indebted to Sir W. Jardine for two specimens of the 

 young of this species, which were sent from the Tweed. — 

 Yarrell. "The Fringe-Lipped Lamprey, Petromyzon Planeri, 

 was twice taken in twenty fathoms water off Bedcar." ? M. ?

Not uncommon. — Dr. G. Johnston. Too common on our 

 coast, and frequently taken on the fishermen's hooks. "It enters 

 the mouths of fishes when on the hooks of lines that remain a 

 tide under water, and totally devours the carcase, except skin 

 and bones." — Fleming. The extreme abundance of the Myxine 

 or Hag on the East Coast may be inferred from the fact that 

 123 specimens were taken out of one Codfish at Bedcar last 

 winter (1843).— T. Meynell. R. 



Scjb-Class. LEPTOCARDII. 

 The Lancelet, or Amphioxus lanceolatus (Pallas), Branchiostoma 

 lanceolatum, Gray, is the only British or European representative 

 of this sub -class. As it is widely distributed, it is a species 

 very likely to occur on our coast, and it is very desirable that 

 collectors and those interested in the pursuits of Science should 

 be on the alert to secure a specimen for our Collection. It has 

 been recorded as occurring once at Bedcar, which may, as far as 

 the distribution of Fishes is concerned, be regarded as in our 

 own district.
