5. Exocorrus. 285 



14. Exoccetus spilurus. 



D. 11. A. 8. 



A single flat barbel at the chin, half as long as the head. The 

 pectoral fin extends to the root of the ventral, the ventral to that of 

 the caudal. The insertion of the ventral is midway between the 

 head and the root of the caudal. Dorsal fin moderately elevated, 

 the last rays reaching the caudal ; the height of the body is not more 

 than the length of the head, which is short and thick. [Snout very 

 short; eye very large ; interorbital space wide, concave*.] Upper 

 parts transparent, colourless, lower parts brown. A small black 

 spot at the base of the barbel, and a larger one in the middle of the 

 root of the ventral ; upper part of the gill-opening black. Pectoral 

 colourless, with a triangular black spot at the base ; ventral and 

 anal fins black. 



Habitat ? 



a-b. Two and a half inches long. From the Haslar Collection. 



15. Exoccetus orbignianus. 



Exoccetus orbignianus, Cuv. Sf Veil. xix. p. 131. 



A single short and broad barbel at the symphysis of the lower 

 jaw. The ventrals extend to the caudal, the pectorals not to the 

 anal. Dorsal fin very high ; anal very low, commencing behind the 

 origin of the dorsal. Body slender, head short. (Val.) 



Southern Atlantic (Montevideo). Five inches long. 



2. Pectoral Jins long, more thmi half as long as the body (tvithout caudal). 



16. Exoccetus solandri. 



Exoccetus solandri, Cuv. Sf Val. xix. p. 129 (not synon.). 

 D. 11-12. A. 9. 



Lower jaw with a cutaneous fringe, which, in the middle, is pro- 

 duced into a barbel, not quite half as long as the head. The pectoral 

 fin extends to the end of the dorsal, and the ventral still further ; 

 insertion of the ventral nearer to the root of the caudal than to the 

 end of the snout. Dorsal fiu very high, the longest rays reaching 

 beyond the root of the caudal. The height of the body is less than 

 the length of the head ; snout about as long as the eye. Dorsal fin 

 black above. 



Indian Ocean (Seychelles). 



«. Four inches long. Presented by Dr. A. Giinther. 



According to our present knowledge of these fishes, Cj/psehirus 

 pulchellus, Lowe, Proc. Zool. Soc. 1840, p. 38 ; or Trans. Zool. Soc. 

 iii. p. 13, from Madeira, cannot be specifically separated from C. so- 

 landri. If the two fishes should prove to be identical, the name 

 given by Lowe would have the priority. 



* These charncters are probably peculiar to young age only.
