10. Hemirhamphus bro-wni. (Cuv. & Va.1., xix, 13, iy46.) 

 Spccimeus iufair conditioiK .32"^. Plee: Martinique, 1821. 

 Scales 52 (not 65, as stated by Valencieunes). This is identical with 



Ilcmirkamphus jplcei, as understood by Meek and Goss (Proc. Ac. Nat. 

 Sei. Phila., 1884,221), and the name broicni is prior to that oi pleei. 



It is extremely doubtful whether the Hemirhampliufi halao, hrasiliensis, 

 or macroGhirus of authors be really a species distinct from this. We 

 may therefore regard them as constituting a single species, for which 

 we' may employ the oldest tenable name used for a member of this 

 gnmp, Hemikhamphus balao Le Sueur. 



The name Usox hrosilicnsis must, as stated by Meek and Goss, go 

 with the Timiicit of Marcgrave, a Tylosurus, and not with the Ilemi- 

 rliamphns. 



11. Belone caribbaea. (Cuv. & Val., xviii, 431, 1846.) 



Three specimens, in good condition, the largest a little over two feet 

 long. Martinique: Plee (not the original types of Le Sueur, which 

 came from Guadeloupe). 



Snout 2^ times length of rest of head ; the jaws very slender, not 

 quite closing, there being a slight arch at base of upper jaw. Teeth 

 comparatively weak. Eye 2-j^ in postorbital part of head. Toj> of 

 head striated, with median groove and the vertex covered by skin. 

 Folds of skin across preopercle, as in Tylosurus raphidoma. Body broad, 

 but compressed, the sides a little flattened. Breadth of body f^ its 

 depth, which is about equal to postorbital part of head. Keel on tail 

 decidedly strong, stronger than in T. raphidoma, and black, the tail 

 otherwise not much depressed. 



Scales small, green, about 210 before dorsal. Ventrals inserted mid- 

 way between base of caudal (mesially) and middle of eye. Anal in- 

 serted just a little before dorsal. Dorsal with its posterior rays elevated, 

 especially in the smaller specimen; broken in the larger. D. 25; A. 22. 



This is doubtless identical with the Belone aUipinna of Poey, which 

 species may therefore stand as Tylosukus caeibb^us. Its distinc- 

 tion from Tylosurus acus is questionable. 



12. Belone timucu. (Ciw. &, Val., xviii, 426, 1846.) 



One specimen in poor condition, .23°^ in length, from Cayenne. A 

 specimen with the same label and belonging to the same species is in 

 the collection from Cuba ; Eamon de la Sagra. 



Body slender, little compressed, the caudal peduncle compressed, but 

 with the lateral line so prominent as fairly to constitute a keel. Beak 

 long and slender, the snout double the length of the rest of the head. 

 Eye small, 3^ in postorbital part of head. Ventrals midway between 

 base of caudal and middle of opercle. D. 13 or 14, A. 15 or 16. Lat- 

 eral baud more distinct than in T. marinus. 



It is not possible to say whether the original Timucu of Marcgrave 



(= Esox hrasiliensis L.) is the present species, or T. suhtrnncatus, or some
