MEYER & PLIENINGER, 1844 221 



the genus Ophichthus of Ahl. Mur.^na ophis Bloch is probably the same 

 and M. ophis Lac. seems to be drawn from the same material. The figure 

 of Lacepede is the sole basis of Cuvier's Mur^na maculosa. All these 

 accounts seem to refer to the fish called Ophichthus havannensis (B1. 

 & Schn.). The maculosus of Kaup and Giinther is a different fish, a 

 species of Myrichthys. McClelland places "Ophisurus ophis Lac." first 

 among his species of Ophithorax. We therefore take it as his type, although 

 his description is rather dubious. "Dorsal fin broad, anal narrow ; body and 

 dorsal covered with large round spots. Pectoral fin very minute. Seas of 

 Europe." The genus is defined : "Pectoral fins very small so as to be scarcely 

 perceptible." It is possible that this description applies to the species called 

 Ophichthys maculosus by Giinther (not by Cuvier). This is a species of 

 Myrichthys, thus far without tenable name. Using Giinther's description 

 of Ophichthys maculosus as the type, the species may be named Myrich- 

 thys guntheri Jordan. It seems best to regard Ophithorax as a synonym 

 of Ophichthys Ahl, rather than to substitute it on doubtful grounds for 

 Myrichthys or for Chlevastes (colubrinus ).
