the genus Opbichthus of Ahl. Mur-bna ophis Bloch is probably the same 

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

 of Lacepi-dc is the sole basis of Cuvier's Ml'R-ena maculosa. All these 

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

 & Schn.). The maculosus of Kaiip and Giintlicr is a different fish, a 

 species of Mvrichthys. 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 

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

 Mvrichthys, thus far without tenable name. Using Gunther's description 

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

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

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

 Myrichtiivs or for Chlkaastes (colubrinus).
