the genus doodca, and it helongs to the subfamily Goodeimv, which has the 
general characters of the Po:ciUin(v,\n\i with bifurcate or trifurcate teeth, 
aud no great differences between thesexes. {cEvoi, strange ; tvoov, within.)

Xeneudinn calietiie ditfers from A*, hntpoldii in having fewer scales in the 
lateral and transverse series and on the caudal i»eduncle, and in a similar 
way from A', xaliscone, besides having villiform teeth, which are absent in 
A", xaliscone. (.Jordan & .Snyder.)
