260 EXI'KDITIOX OF THK " AI,HAT1U)SS," lSfl<)-l!)()(). 



In Fishes of Samoa, Jordan & Seale have represented the genus Myxus with 

 one species, M. leiiciscus, and Chaenomugil with two species, C. chaptali Eydoux 

 & Souleyet and C. nauticus Bryan & Herre. 



In the synonymy of C rhnptali they place Mi/xus pdcijicus Steindachiu r, 

 and in a translation of Steindachner's description by .lordan ^ Kvennaim in 

 Fishes of Hawaii, it is indicated that there are two rows of small movable 

 teeth on the upper lip. Steindachner states that the intermaxillary has a band 

 of small movable teeth in which those of the outer row are larger than those 

 of the other rows; the border of the mandible is shar]), with a horizontal row 

 of small movable teeth; he also distinctly states that the uppei- Wp is rather 

 small and the eye has a well developed adipose eyelid. 



This last character removes it from Chaenomugil or JVIyxus. In the descrip- 

 tion of Chaenomugil nauticus Bryan & Herre, the teeth are not described with 

 sufficient definiteness to indicate clearly whether it is a Chaenomugil or Neo- 

 nwxus but the upper lips "not thick" would indicate that it belongs to the latter 

 genus. Furthermore there is nothing in the description to indicate that it is 

 not a Neomyxus. In the larger numbei- of scales, large eye?, narrow inter- 

 orbital, and long first ray of dorsal and of anal it seems to tliffer from any de- 

 scribed species.
