Classification of the Order Apodes. 



3S5 



The suggestion that Cyema is a Nemichthys with regene- 

 rated tail cannot be entertained ; the four specimens known 

 are extremely similar and the posteiloi- caudal vertebrjB 

 decrease in length backwards in a perfectly regular manner. 



Family 11. Mursenesocidae. 



Murccnesox is related to the Congridse, but the maxillaries 

 are articulated to the ethmoid at a considerable distance from 

 the end of the somewhat produced snout, the ribs are rather 

 strong, and the caudal vertebrai are formed as in the Anguil- 

 lida?, without lateral transverse processes. The jaws have 

 strong anterior canines and the vomer is armed with a median 

 series of large teeth. 



Family 12. Congridae. 



Dorsal and anal fins continuous with the reduced caudal; 

 body naked; vent remote from head. Mouth with lateral 

 cleft, not extending far behind eye ; maxillary articulated 



Fijr. 2. 



^sp -pro osp 



Conger conger. Skull from above and from the side. 

 Lettering' as in fiof. 1, 



with ethmoid near end of snout; teeth conical, cardiform, or 

 compressed, in bands or in one or more series, well developed
