Speciraeus were taken from A^plenium ciaiecdum 

 Lam., at Rio de Janeiro, described and figured by Goeldi 

 as having 5 pairs of long, slender spines on the uuder 

 surface. Speciraens of extranius studied by Quaintance 

 and Baker show the two to be alike, only in extranius 

 the five spines are on the dorsal surface. The condition 

 of the ventral spines is so remarkable that thesc two 

 co-authors felt that Goeldi liad raade a mistake, but the 

 same thiiig was described by Douglas in 1890, and bacau- 

 se of the statements of these two describers they retained 

 the two specific ñames.

 al plaut at Berlice, British Guiana, by Mr. G. E. Bod-

 on the leaf as the only material we have is monnted on 

 seven slides.
