XLII. — Descriptions of three new Species of Fishes in the Col- 

 lection of the British Museum. By Dr. Albert Gunther.

Tliis species is evidently closely allied to D. mediterraneum of 

 Guichenot ; but it has fewer anal rays, differently coloured fins, 

 and a less elevated body. The height of the body equals the 

 length of the head, and is less than one-third of the total length 

 (without caudal) ; the head is considerably longer than high, 

 and its upper profile does not descend very abruptly. The dia- 

 meter of the eye equals the length of the snout and the width 

 of the interorbital space, and is two-sevenths of the length of the 

 head; the maxillary extends to below the anterior margin of the 

 orbit. Small scales advance to between the nostrils, and cover 

 the prseorbital almost entirely. Dorsal spines of moderate 

 length and strength, the fifth, sixth, and seventh being the 

 longest, and two-fifths of the length of the head. The posterior 

 spinous passes gradually into the soft portion of the dorsal, without 

 being separated from it by a notch. The second anal spine is not 

 longer, but stronger, than the third, and is longer and stronger 

 than any of the dorsal spines. Caudal fin truncated. Pectoral 

 rather longer than ventral, the latter not extending to the vent. 

 Scales ctenoid, those of the lateral line irregularly arranged. 

 Head and body blackish ash-coloured ; all the fins and the free 

 portion of the tail bright lemon-coloured, with a greenish tinge. 



A single very fine example, 11 inches long, was obtained by 

 the Rev. R. T. Lowe, during his last sojourn in the Cape de 

 Verde Islands. 



Therapon percoides.

The height of the body is contained twice and a half in the 

 total length (without caudal) ; the length of the head twice and
