Dimenaiona of Quadrella nitida. 



By Dr. Ortmaiin this si)ecies is united with (^). voronata Dana. I have 

 not seen specimens of the latter. (^. nitida has only one carpal spine 

 instead of the two in coronata. The sinuses separating the median 

 irom the next ])air of frontal teeth are more shallow than rei)resented 

 in Dana's ligure, and the lateral margins are much more convex.
