THE CANADIAN ENTOMOLOGIST. 29 



I consider as of superfamily rank. With the exception of these two 

 unwarranted (as I thinic) associations, there seems Httle fault to find with 

 the classification. I will leave to Mr. Grote the correction of the family 

 and superfamily names, as he has paid especial attention to the determina- 

 tion of types, and the effects of the application of priority rules. The 

 importance of such work is made very evident by Mr. Meyrick's book, 

 if we are ever to have a uniform and stable nomenclature. 



It is evident now that Lepidopterists are practically agreed on the 

 general classification of the Frenatre. As to the exact limits of super- 

 family groups, there is yet, unfortunately, scarcely an approach toward 

 agreement. Harrison G. Dvar.

Under this title has been given to the public a work which bears out 

 in every way the deservedly high reputation of the writers. From its 

 style of treatment of the subject, the book may be read with pleasure and 

 profit by general student and specialist alike, while to the instructor who 

 wishes to bring before his pupils the results of late researches, though out 

 of reach of large libraries, it will prove a most valuable aid. 



The chapter on Peripatus^ by Mr. Sedgwick, is in itself a model 

 memoir, and the twenty six pages devoted to the curious creature are 

 made up for the most part of original studies by the author, who has 

 previously published important monographs on this subject. The histor- 

 ical and morphological matter, which is fully illustrated by fine figures, 

 is followed by a synopsis of all the known species, with notes on their 

 differential characters and geographical distribution — the map which forms 

 the frontispiece of the volume showed them to be confined to the region 

 south of the Tropic of Cancer. The discussion of the affinities of 

 Peripatus to the Arthropoda and Annelida is of great interest to the 

 zoologist, whatever his beliefs in regard to the theory of descent. 



From Mr. F. G. Sinclair we have the chapter on Myriapoda. The 

 preliminary account of these animals contains some charmingly written 

 notices of their habits, and marks the author as a faithful observer in the 

 field as' well as in the laboratory. A short sketch of the classification 

 follows, with brief definitions of the families and figures of typical forms,
