sides, ami abiloiiion yet iwovc Linlitly rolled dorsally. IL forms avi almost perfect 

 sphere and falls to the ground, attempting no active defence, and its naturally slow 

 movements effectually precluding escape, except perhaps by flight. If this be 

 mimicry, wherefore is it? The integument of Encephalus is, we may assume, 

 nearly or quite as ehitinous as that of Clamhus, and the former probably possesBes 

 greater powers of exuding protective liquids. Truly is its name appropriate in 

 more than one sense ! 



I took E. compllcans in tufts in Suffolk on April 17th. This is its first recorded 

 capture in the county since that near Blakenham by Rev. William Kirby, F.R.S., 

 recorded by Stephens. — Claude Morxey, Tpswieh : April, 1901.

It is a common practice with continental (especially teutonic) Societies to cele- 

 brate (heir Jubilee by the publication of a volume of original Memoirs. The bulky 

 volume .sent out by the very useful Society under notice is of a somewhat different 

 nature, anil is in fact a careful review of the work done in Austria during the fifty 

 years of the Society's existence, and an account of the workers. This latter part is 

 rendered of additional interest by the numerous full page portraits interleaved in 

 the text, giving us an idea of the personal appearance of the bearers of familiar 

 names. There is also an excellent account of the various museums in the 

 eoiuitry, with illustrations of most of them. From a detailed account of the history 

 of the .'^ociely (by ])r. C. Brunner v. Watlenwyl) it would appear that it originated 

 under the title of " Freunden der Natur " and " Freunde der Naturforschung," and 

 from these beginnings the Society as it now exists expanded. It is useless to go 

 here into exhaustive details ; these are sufficiently exhaustive in the book itself, 

 wliich owes mneh of its completeness to the energy of Dr. A. Handlirsch and Dr. R. 

 V. Wattstein, but the luuiiber of authors who have contributed towards the building 

 up of the work is great, and we must not omit Dr. K. W. v. Dalla Torre, who (infer 

 alia) supplies a complete list of works and papers on Botany and Zoology pub- 

 lished in the half century, and arranged chronologically to the number of 1200. 

 This Festschrift is invaluable as a book of reference, and reflects the greatest possible 

 credit upon all those who assisted in its production.

Although Spiders are not true Insects, they ai'e, or at any rate have been, gene-

 araclmologists are, like the compiler of this List, entomologists also. Therefore, no
