Mjirophis microstlr/mius, Poey, Repert. Fis.-nat. ii. p. 250, from 

 Cuba, would appear to differ from M. punctatus only in the more 

 backward situation of the origin of the dorsal fin, which is said to 

 be midway between the giU-opening and the vent, whilst in the 

 specimens of M. punctatus examined by me the origin of that fin is 

 distinctly nearer to the gUl- opening than to the vent.
