other, but in Tiew of the difference in the place of the vent they may 

 be considered as separate genera. The vent is very slightly nearer 

 base of caudal than the axil of the pectoral in Trachrmocephalus. In 

 Synodus, the vent is much nearer base of caudal than base of ventrals. 



This must be Synodus hrevirostris Poey, said to have 10 anal rays and 

 ventral under middle of pectoral. In most other respects Pocy's 

 description agrees, and is doubtless the same species. 



EXOCCETID.E. 

 12. Tylosurus subtruncatus (Poey). 



One specimen, agreeing entirely with those from Cuba. This is prob- 

 ably the TimuGu of Marcgrave, but not the Belone tinmcu of Cuv. & 

 Val. 



13. Heniiramphus pleii (Cuv. & Val.). 



Scales 53; ventrals midway between base of caudal and middle of 

 pectorals. This species is probably identical with Eemiramphus hmsil- 

 ie7isis. The latter name is the older. 



14. Hemiramphus unifasciatus Ranzani. 



Numerous young specimens. 



MUR^NID^. 



15. Gymnothorax moringa (Cuvier). 



One adult. 



16. Gymnothorax funebris (Ranzani). 



Adult and young. 



17. Gymnothorax vicinus (Castelnau). 



One adult. This is probably Murcenophis vicina of Castelnau, but 

 probably not his M. camaruru. The specimen from Cuba called by me 

 elsewhere ISidera vicina is probably also different. I can not distinguish 

 the 3Iurwna maculipinnis of Kaup from this species. Brown, mottled 

 with darker brown; angle of mouth dusky; dorsal edged with dusky, 

 anal with whitish ; dorsal mottled like the body ; no black spot at gill 

 opening; eye, 2 in snout; mouth, 2^^ in head; tail longer than body ; 

 jaws closing completely ; maxillary teeth in one row ; head l^o in trunk. 



CONGRIDtE. 

 18. Muraenesox savanna (Cuvier). 

 Brown above, silvery below ; dorsal and anal edged with black ; pec- 

 toral with black tip; dorsal beginning just before pectoral; pectoral 

 as long as maxillary, 2^^ in bead. Kje, 2^ in snout; edges, 4^ in head. 

 Teeth not lobed, but the surface uneven. This is evidently Conger 

 limbatus Castelnau.
