the first dorsal. Ventrals reaching a little beyond the pectorals, but falling short of the anal by 

 a space equalling half their own length. 



D. 8—9; A. 7; C. 15, &c. ; P. 10; V. 1/5. 



Length 8 inches. 



Colour. — "Vermilion, with streaks of iridescent blue."— D. Inspirits, the colour appears of a 

 uniform dull reddish yellow, without any indication of spots or other markings on the fins or 

 body. 



Habitat, Porto Praya, Cape Verde Islands. 



I suppose this to he the U. Prayensis of Cuvier and Valenciennes, the descrip- 

 tion of which, so far as given in the " Histoire des Poissons," is tolerably applica- 

 ble. Those authors, however, mention a spot in the middle of each scale of a 

 deeper red than the ground colour, which is not alluded to by Mr. Darwin in his 

 notes, and of which I see no trace on the fish in its present state. On the other 

 hand they are silent with regard to the blue streaks. In some of its characters, 

 especially as regards the teeth, this species seems to approach the U. maculatus ; 

 but the colours are different in this last also, which is moreover found on the op- 

 posite side of the Atlantic.

Form. — In general appearance very much resembling the T. Hirundo, but more elongated. Depth 

 contained about five times and a half in the entire length. Head rather more than four times 

 and a quarter in the same. The obliquity of the profile about the same as that of the T. Hirundo, 

 but the concavity of the interocular space less. The granulations on the head not so coarse, or 

 so strongly marked, the lines in which they are arranged being closer and more numerous : 

 those on the suborbitals radiate from a point nearer the extremity of the snout : no crest or 

 ridge at the bottom of the suborbital, and only a very indistinct one at the bottom of the pre- 

 opercle : as Cuvier has well noted, the grains on the border of the preopercle are divided into 

 little isles, or collected in clusters, by irregular lines which undulate amongst them ; and in 

 this specimen, the same character presents itself on the posterior and upper portion of the 

 suborbital: some of the first lines on the opercle are plain, or without granulations. Snout 

 emarginated, with three or four denticulations on each side rather sharper and more developed
