species with hairy eyes. The removal of cespitis from the genus 

 Lupcrina also seems to be well warranted; Mr Barrett places it 

 with pop>ularis in his genus Hdiophohus. It is to he regretted 

 that no authorities are given lor the generic names, nor is any 

 justification advanced for such changes in nomenclature as that 

 just mentioned, Heliophobus in our current lists being assigned to 

 the species hispidus, for which Mr Barrett uses the generic name 

 ZTIochlaena. 



A more serious fault, mentioned in the notice of previous 

 volumes, is the absence of any synoptical table of generic 

 characters. In a few cases in the present volume Mr Barrett has 

 given such a table of the species in a genus, but, as a rule, a 

 beginner desiring to name a moth from the plain edition of this 

 work would have to plod steadily through all the descriptions. 

 The summaries of the varietal forms of each species are compre- 

 hensive and valuable, and in his descriptions of the caterpillars 

 the author has followed the best authorities. Tlie pupa, however, 

 which is worth careful study, is in most instances passed over with 

 the most meagre notice. The distributional facts regarding each 

 species are stated in detail, and a valuable feature is a summary 

 of the foreign range in addition to the British. A few moths are 

 mentioned — as Miselia himaculosa and Xylophasia zollitoferi — of 

 which one or two examples only have been taken in England. 

 Mr Barrett is inclined to explain such occurrences by supposing 

 artificial introduction. But it seems at least as likely that the 

 species are really indigenous, although of extreme rarity, and only 

 able to hold their ground in a few scattered localities which have so 

 far escaped the vigilance of the rapacious collector.

The American Forestry Association has taken over The Forester as 

 its publishing organ. 



The Plant World was started last autumn somewhere in the 

 United States. We have not yet seen a copy or been furnished with 

 any details. 



Our weekly contemporary, Garden and Forest, has ceased publica- 

 tion on the close of its tenth volume, having failed to find a paying 

 public in the United States. Those who have paid will undoubtedly 

 regret this decision. 



Prof. 0. Taschenberg has been succeeded as editor of the weekly 

 journal, Die Natur, by Prof. Willi Ule, under whose auspices we may 

 look for the continuance of a career that has already been successful 

 for forty-six years. 



The Bausch & Lomb Optical Co., of Ptochester and New York, 

 published on January 1 the first numlier of their monthly journal, 

 which is devoted wholly to the microscope, its use, methods of 

 working, fixing, mounting, &c. This is the first paper of its kind 

 published in the United States. 



We have received the annual bound volume of our interesting 

 monthly contemporary, Knowledge, for 1897. It would form an
