Genus MYXOCYPRINUS Gill. 



Myxocyprinus GILL, Johnson's Cyclopaedia, p. 1574, 1878. 

 Carpiodes et Sderognathus sp. BLEEKER, GUNIHER. 



Type, Carpiodes asiaticus Bleeker. 



Etymology, /nv^ao, to suck ; KV-xpivo?, a carp. 



This genus is known to me only 2rom Dr. Bleeker's description of its 

 typical species. Whether it differs from its relatives, Ichthyob-uSj Buba- 

 lichthys, 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 multiradiate dorsal and anal fins 

 (e. g. D. 52 ; A. 13)." (GiLL, Johnson's Ctjdopcedia, Appendix, p. 1574.)
