Genus MYXOCYPRINUS Gill 



Myxocyprinus Gill, Johnson's Cyclopaidia, p. 1574, 1878. 

 Carpiodes et Sclerognathus sp. Bleekkr, GtJNTHER. 



Type, Carpiodes asiaticus Bleeker. 



Etymology, fiv^au, to suck ; KVTzpcvog, a carp. 



This genus is known to me only l"oui Dr. Bleeker's description of its 

 typical species. Whether it differs Irom its relatives, lohthyobus, Buba- 

 Uchthys, etc., in any other character than the obvious one of the great 

 increase in the number of its dorsal rays and the smaller scales, I do 

 not know. In any event, however, its right to independent generic rank 

 is unquestionable. 



Generic Characterizations. 



Myxocyprinus Gill, 1878. — " Myxocyprinus is a name proposed for the Carpiodes 

 asiaticus of Bleeker, which is distinguished by the multirudiate dorsal and anal fins 

 (e. g. D. 52; A. 13)." — (Gill, Johnsoti^s Cyclopaidia, Appendix, p 1574.)
