This 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 preorbital 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 spies. Caudal fin truncated. Pectoral 
rather longer than ventral, the latter not extending to the vent. 
Seales 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, 1] inches long, was obtained by 
the Rev. R. T. Lowe, durimg 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
