308 ADDENDA. 



of the second dorsal and anal : both the last-named end near the tail, this 

 posterior portion being so low as to be scarcely perceptible, and even the 

 anterior portion of the dorsal very slightly so. Ventrals under the first dorsal : 

 the tail rather wide, incurved, the anterior border of it, above and below, narrow 

 and almost touching the lower rays of the second dorsal and anal. Scales of 

 moderate size and very deciduous. Lateral-line commences above the hind 

 edge of the gill-covers, and passes direct to the centre of the tail. Colours 

 silvery, darkest along the back, and a row of spots or marks along the lateral-line. 

 Habitat. Mediterranean, where it is rai*e. The Cornish specimen alluded to is 

 10 inches long, and in spirit. It was caught by the hand when alive in 1809, by 

 Mr. Dunn at Polkerris pier, near Mevagissey, and was supposed to have been 

 wounded by some other fish. Mr. Dunn sent it to Couch, who presented it to the 

 British Museum. But it was not included in the British Museum catalogue. 

 After my having been allowed access to Mr. Couch's Journals, and published his 

 account in the Zoologist, Dr. Giinther showed me the identical specimen in the 

 National collection.
