9. On the Occurrence of Lumpenus lampetriformis off the 

 East Coast of Scotland. By Francis Day. 



[Keceived June 16, 1884.] 



(Plate XLI.) 



On May 31st this year I received information from Professor 

 Mcintosh, of St. Andrews, that a fish new to the British fish-fauna 

 had been captured 15 miles off St. Abbs Head in 40 fathoms water by 

 means of a trawl ; and a few days subsequently he was good enough 

 to send me the specimen, with permission to figure and describe it. 



The fish is in excellent condition, 10*7 inches in length, and 

 belongs to the Blenniidse. Different generic names have been given 

 to the genus to which it pertains, as Stichceus and Ctenodon ; but 

 Gill (Proc. Acad. Nat. Sci. Philad. 1864) showed that Lumpenus 

 has the priority ; and Collett (Norwegian North-Atlantic Expedition,
