446 THE ZOOLOGIST. 



Crayfish, which is abundant in many of the Gloucestershire 

 streams and rivers, though it appears that none have yet been 

 found in the Severn. The author of this chapter, Mr. Edwin 

 Burgh, throws out the suggestion that in these times of agricul- 

 tural depression, it might be worth while for farmers who have 

 suitable water, to breed Crayfish and send them via Bristol to the 

 French market, where (as a delicacy) they always command a high 

 price. 



The remaining sections of the volume (excluding the Botany) 

 deal with the Mollusca, of which 108 species are catalogued ; the 

 Ants of Gloucestershire, concerning which there is a long con- 

 tribution by the Kev. W. F. White ; the Hymenoptera (pp. 1 96— 

 243) ; and the Macro-Lepidoptera (pp. 244-259). Few counties 

 can show such a record of good species of butterflies as are to be 

 found in ordinarily favourable seasons in Gloucestershire, and 

 entomologists will find much to iuterest them in this section of 

 the work. 



Mr. Witchell's attempt to bring together in a volume of con- 

 venient size as much reliable information as he could collect on 

 the zoology and botany of the county in which he resides, is 

 extremely commendable. It is by no means exhaustive, nor 

 does the author, we imagine, profess it to be so ; but it will 

 supply a blank in the list of county faunas and floras, and will, 

 we trust, in a second edition, lead to something still better.

A great number of moths were described by the late Francis 

 Walker from the collection of the British Museum, where the 

 types still exist, and may be easily traced ; but he also described 

 several hundred species from the collection of the late Mr. 

 Wilson Saunders, who at that time possessed the finest private 

 entomological collection in England. The most important 

 portion of Mr. Saunders' types were those from Sarawak, 

 described by Walker in the ' Journal of the Linnean Society ' 

 (vols, vi.-vii.), to which, strangely enough, Col. Swinhoe makes no 

 special allusion in his preface.
