nomenon. As described then, In December, the drooping twigs 

 (on all but one of the main branches) curl up until each twig 

 reaches a position above its point of origin, and the tree has a 

 round-topped, bristly appearance. The writer will be much 

 indebted to any one contributing observations, photographs, etc., 

 of a willow tree showing similar changes; dates of the observed 



changes are also desirable.

Mr. Albert J. Hill, M.A., who collected the plant several years 

 ago, says it is not rare in the above locality. It is quite distinct

 excellent work, the third and supplementary volume of which 

 has just appeared, is a model for a similar work on our American 

 cecidia. This third volume contains brief, clear descriptions of 

 1,317 species of galls distributed among 149 genera of gall 

 makers and in 92 families of host plants. The species are grouped 

 with reference to the taxonomic order of the host plants on which 

 they occur but zoological and botanical indices makes the work 

 very valuable for both entomologist and botanist. A very 

 unique system of abbreviation on the margins of the pages 

 indicate the location of the gall on the host plant and its geo- 

 graphical distribution. The illustrations are mostly line draw- 

 ings but are of such character as to greatly facilitate the deter-
