234 OSTEOLOGY OF MUR/ENESOClDiE GILL. 



1. Mura;iies()x M'Clelland, C;il<;iitl:i Joiini. Nat. Hist., v. 4, p. 40S, 184:5. 

 Type M. cincreus (Forsk). 



Murseuesocids with enlarged tricuspidate cultrate and acute teeth 

 along the middle of the vomer (an teal) and compressed cultrate acute 

 teetli in the middle row of the mandible. 



2. C.ynoponticii3 Costa, Fanua Napol. = Brachy conger, Bleeker Atlas Icli. Ne6rland. 



Ind., V. 4, p. 19, 1864. 

 Type C. savanna (Cuv.). 



Murtenesocids with enlarged tricuspidate, bluntly edged teeth along 

 the middle of the vomer and little compressed bluntly edged and truu 

 cated teeth in the middle row of the mandible. 



3. Congresox Gill = Muneuesox sp., M'Clelland, Bleeker et al. 

 Type C. talabon =■ Conger taJabon Cuv. 



Muraenesocids with enlarged and mostly acutely conic slender teeth- 

 aloug the middle of the vomer and similar teeth in the middle row of the 

 mandible. 



I have examined crania of Murccnesox* and Gynopotitmis, but not one 

 of Congresox. The iirst two genera differ in details but are much alike 

 in cranial characteristics, and (contrary to the generic diagnosis of 

 Bleeker) differ very slightly and only in degree in the contraction of 

 the anteal behind its head. 



* That of the Miirseuesox (M. ci7iereus) is imperfect and broken behind.
