Needham, J. G. & Needham, P. R. 
A guide to the Study of Fresh-water Biology. 88 pp. American 
Viewpoint Soc. New York & Albany, N. Y. 
This is a very practical compendium of the fauna and lower plant 
organisms of fresh-water ponds and streams. As might be expected, 
the major portion of the text relates to insects, but the several other 
groups are covered equally well. There are an enormous number of 
good line drawings, and these, together with dichotomic keys for 
the determination of the organisms, occupy the bulk of the book. 
Aside from its value to young students of biology, it should be 
very useful to the more mature biologist' who disdains the intricacies 
of taxonomy.

Garman, Philip 
The Odonata or Dragonflies of Connecticut. Bulletin 39, State 
Geological & Natural History Survey of Connecticut. 1927. 
The present volume of 331 pages, illustrated by 67 figures and 22 
plates, is the latest addition to the “Insects of Connecticut.’ ’ Many 
of the figures contain ten or more well executed line drawings and 
leave little to be desired in the way of illustration. In addition to 
keys and descriptive matter in the text, pertaining to the imaginal 
dragonflies, the nymphs are dealt with in great detail. All in all, 
this compendium will be a great boon to entomologists in New 
England.

Buxton, P. A. & Hopkins, G. H. E. 
Researches in Polynesia & Melanesia. Mem. Series No. 1, London 
School of Tropical Medicine, 260 pp. London 1927. 
This is a very beautifully prepared account of the bionomics of 
Aedes variegatus and A. argenteus and contains much other material 
of interest to medical entomologists. 
Of particular interest to general biologists is a chapter on the 
“Climate of Samoa, ” which discusses temperature and humidity 
in relation to the biological environment, together with some very 
sane observations on the use of physical instruments for recording 
such data.
