three enlarged depressible canine teeth below the eye, as seen in the 

 inner series in the upper jaw. 

 Gymnothorax flavimarginatus (Ruppell). 



Three from Padang, Sumatra. Of these one now in Stanford 

 University. They all agree with Ruppell's description to some 

 extent. They differ from his figure in having only pale or dull- 

 edged fins posteriorly. The figures by Bleeker have sharp-pointed 

 teeth and may be different. Ruppell says, of M. flavimarginata, 

 that it is very large, both jaws have a row of strong wedge-shaped 

 teeth and the throat equally with similar teeth. The palatine teeth 

 are said to be four long curved depressible teeth each side. 



Gymnothorax batuensis (Bleeker). 



One from Apia, Samoa. Apparently not identical with Murcena 

 flavimarginata Ruppell, as thought by Jordan and Seale. 



Gymnothorax kidako (Schlegel). 



One from Tokyo, Japan. 



Gymnothorax moringua (Cuvier). 



Two from Bermuda Islands; one from New Providence, Bahamas; 

 one from St. Kitt's, West Indies; one from St. Thomas, West Indies; 

 three from St. Martins, West Indies. 

 Gymnothorax funebris Ranzani. 



One from Santo Domingo, West Indies. Another without data. 



Gymnothorax concolor (Abbott). 



Thyrsoidea concolor Abbott, Proc. Acad. Nat. Sci. Phila., 1860, p. 479. 

 Vera Cruz, Mexico. 



No. 970, A. N. S. P., type of T. concolor Abbott. I have allowed 

 this as a distinct form, Abbott's name having priority over Murcena 

 erebus Poey, 19 which is said to have uniserial vomerine teeth. M . 

 infernalis Poey 20 is said to have biserial vomerine teeth and also be 

 identical with G. funebris Ranzani, though the latter does not de- 

 scribe the vomerine teeth. Jordan and Davis remark "there is 

 no doubt of the identity of funebris, concolor, castanea and infernalis," 

 though later Jordan and Evermann suggest castanea as probably 

 distinct. 



Gymnothorax unicolor (De la Roche). 



One from Italy. 



Gymnothorax carcinognathus sp. nov. Fig. 5.
