288 SCOMBRESOCID.E. 



beyond the dorsal and anal, nearly to the rudimentary rays of the 

 caudal. Ventral fins nearly midway between the eye and the root 

 of the caudal, extending to the end of the base of the anal. The 

 dorsal commences a little behind the origin of the anal ; its anterior 

 rays are half as long as the head. There are twenty-nine scales 

 between the occiput and the origin of the dorsal, and six or seven 

 longitudinal series of scales between the origin of the dorsal and the 

 lateral line. Pectoral with an oblique white band across its lower 

 half, and with a broad whitish edge. Ventral white, the middle 

 rays greyish.

This is most probably the same species as that named E. specvliger 

 by Valenciennes, although he describes the eye as larger. 



22. Exoccetus aflinis. 



Closely allied to E. specuUcjer, but \vith the snout longer and the 

 eye shorter. 



D. 11-13. A. 11-13. L. lat. 50-52. 



The height of the body is nearly one-sixth of the total length 

 (without caudal), the length of the head one-fourth. The depth of 

 the head equals the distance between the extremity of the snout and 

 the hind margin of the orbit. Snout rather produced, equal in length 

 to the diameter of the eye, which is two-seventbs of the length of 

 the head, and rather less than the width of the interorbital space, 

 which is quite flat. The pectoral fin extends to scarcely beyond the 

 dorsal and anal. Ventral fin midway between the ej-e and the root 

 of the caudal, extending beyond the middle of the base of the anal. 

 The dorsal commences opposite the anal ; the length of its anterior 

 rays is two-fifths of that of the hcdd. There are thirty-five scales 

 between the occiput and the origin of the dorsal, and six longitudinal 

 series of scales between the origin of the dorsal and the lateral line. 

 Pectoral with an oblique white blotch across its lower half, and with 

 a narrow whitish edge. Ventrals greyish. 



Atlantic. 



a. Eleven inches long. Cuba? From the Collection of the Zoolo- 

 gical Society. 



h. Nine inches long. Atlantic. Purt^hased of Mr. Frank. 



e-d. Ten inches long : not in good state. West Africa. From 

 Mr. Eaddon's Collection. 



•This species is perhaps identical with that named by Midler and 

 Troschel-iff. roherti (Schomb. Hist. Barb. p. 675); but their description 

 of it is quite insufficient for the determinntion of the species.
