The Alsines are now in the course of elaboration by Mr. Fenzl, of the Imperial 

 Museum at Vienna, who has the most ample materials at his disposal. A portion of 

 his truly excellent monograph is already published (in Annal. Wiener. Museum.), 

 and considerable alterations are made in the arrangement of the tribe. As bis 

 work is still unfinished, we shall, to prevent confusion, make very few notes upon 

 the tribe at present, but may hereafter give a notice of his arrangement, and make 

 the necessary changes in the synonymy.
