just behind the vent ; it is considerably higher about the middle and 

 behind than in front. The caudal is rounded. The lateral line is 

 distinctly marked ; it falls gently from the shoulder, but for the 

 greater part of its length is straight along the middle of the body. 

 The air-bladder is long, being more than one-third of the length of 

 the body. The food found in the stomachs of dissected specimens 

 consisted of the rem.ains of fishes and crustaceans. The peritoneal 

 lining is of a dark blue colour. 



Dedicated to Dr. Kaup of Darmstadt, who has well studied this 

 order of fishes. Specimens have been sent to the British Museum.

L^MONEMA, Giinther, MS. 



The genus Leamonema, established by Dr. A. Giinther on a Me- 

 diterranean fish hitherto assigned to Phycis, is distinguished from 

 the latter genus by the shortness of the base of the first dorsal fin, 

 and by the rounded outline of the patch of A^omerine teeth. A full 

 diagnosis of the genus will appear in the forthcoming fourth volume 

 of the ' Catalogue of Fishes in the British Museum.' A second 

 species of the genus having occurred, I proceed to describe it.

 M. B. 7- Scales of lateral line about 126. 



Body Phycis-\\ke, thick before, much compressed behind, of a 

 dull-brown colour ; the rays of the dorsal, anal, and pectoral fins 

 being of a dull purplish-red. The scales are very small ; between 

 the base of the first dorsal fin and the lateral line fifteen rows of 

 scales may be counted. The length of the head is equal to the height 

 of the body under the first dorsal fin, and, compared with the total
