nesque. This name is applied by bim to some species with sbort anab 

 His description agrees with the present form better than with any other. 

 This species seems to be one of the most abundant in the Mediterranean. 

 The specimens examined by us are from 9^ to 15 inches in length, 

 and are from the Atlantic and West Indies.

? Exocatus rohnshts, G'lmt'hQT, vi, 1866, 289 (Australia). 



Habitat. — Tropical seas. 



The following description is taken from a specimen in the museum of 

 the academy at Philadelphia : 



Head ^ in length of body ; depth 5^ ; D. 14 ; A. 9 ; 50 scales in lat- 

 eral line; length of specimen 9 inches. Body rather robust. Head 

 broad, rather pointed forwards ; snout not very blunt, ^ in length of 

 head ; eye large, 2f in head ; interorbital area flattish, 3 in head. Pecto- 

 ral fins broad, their tips reaching posterior end of base of anal fin ; length 

 of pectorals If in length of body. Length of ventrals 2f in length of 

 body, their tips reaching nearly to posterior end of base of anal fin ; 

 origin of ventrals midwaj- between pupil and base of caudal fin. First 

 ray of pectoral simple, its length little more than one-half length of fin ; 

 second ray divided ; 23 scales before the ventrals ; 28 scales before the 

 dorsal fin ; 7 rows of scales between lateral line and dorsal fin; longest 

 dorsal ray 2 in head ; lower lobe of caudal about one fourth longer than 

 head. 



Color brownish above, silvery below ; pectoral black on its posterior 

 half; lighter on anterior, with a broad, white, oblique band which be- 

 gins in the axil and extends about two-thirds across the fin ; ventrals 

 white, dusky in axil ; dorsal and anal fin plain ; caudal dusky, with a, 

 black vertical bar across the base of its middle rays. 



The single specimen from which the above description is taken agrees 

 fairly with Dr. Giinther's description of E. robustus. That description 

 is, however, too incomplete for us to consider the identification as at 

 all certain. Our specimen is said to be from "Cape San Antonio." 

 "Whether the cape in Cuba so named is intended, or some headland 

 elsewhere, we are unable to say.
