XXXI. — On the Occurrence 0/ Orcynus alalouga on the Coast of 

 Devon. By Dr. W. 11. Scott. 



Several fish of but rare occurrence in British waters have from 

 time to time been taken on the Cornish and Devon coasts. 

 The close and accurate observations of Mr. Couch have seldom 

 allowed any found on the former to pass unnoticed. On the 

 coast of Devon, however, recorded captures of these rarer spe- 

 cies are less common, owing probably in some degree to the 

 want of that zealous watchfulness which has animated the la- 

 bours of the Cornish ichthyologist. Amongst the rarer species 

 that pay our coasts an occasional visit are those of the genus 

 Tkynnus; and amongst the very rarest of these is the Germon, 

 separated now, however, by Cuvier into a distinct genus, and 

 which fish he has named Orcynus al along a, from the length of 

 its pectoral fin — which constitutes the chief, if not the only, dif- 

 ference between it and the true Tunnies. 



The Orcynus alalonga has been very rarely found in British 

 seas. One has been recorded as taken at Portland, which was 

 presented to the British Museum, and it has been twice taken 

 in Mounts Bay, Cornwall. 



I have pleasure, therefore, in now recording another specimen 

 of this rare British fish, taken in Devonshire. This fish was 

 captured on the 26th of August last, not really in channel, but 

 a little way up the river Exe, about three miles from its mouth, 

 and at about half-tide. The fish had got entangled amongst 

 some palings which had been driven into the river about a foot 

 from the edge, where a kind of quay had been made, and which 

 formed a cul-de-sac. Into this the fish got ; and so violent were 

 its struggles to get out, that it drew the attention of some work- 

 men who were at a little distance, when one of them got his gun
