this could explain why few animals 
were recorded there. On the hills there 
was much less ground cover and 
probably less food, consequently no 
rats or phascogales were trapped 
there. There were however, more oc- 
cupied Wombat burrows in the hills 
than in the valley. 
It is a common habit for Black 
Wallabies to frequent gullies in hot 
weather, but in cold weather they 
generally move to the higher ridges 
and they were only seen on hills in 
the survey area.

Book Roviows 
Australian Sea Shells 
By John Child 
(Published by Cheshire-Lansdowne in the Periwinkle series) 
Lightweight cardboard cover, approx. 5" x 7i". 80 pages and 16 pages of colour 
plates, with 20 half-tone plates and more than 100 in-text line drawings. Price $1.25. 
This is an enlarged and re-set 4th 
edition of a book originally published 
in 1959. After an introductory chapter 
explaining the classification of mol- 
luscs, their importance to man, notes 
on their distribution and ecology and 
an explanation of some of the scientific 
names, the remaining five chapters 
are devoted to the main groups of sea 
shells. In all 108 spscies are described, 
figured as line drawings and an idea 
given of their habitats and distribution 
in Australia. These latter features are 
perhaps the most useful parts of the 
book. 
However, much more care should 
have gone into the preparation of this 
book as it contains a number of errors, 
some quite serious. For instance, there 
is one entire colour page of six plates, 
which have been printed in reverse 
so that all the shells appear sinistral; 
a number of the colour illustrations 
have the wrong captions, and in the 
text, the arrangement is such that Gena 
impertusa appears to be included in 
the Haliotidae instead of the Trochidae. 
The colour plates are poor, both in the 
choice of specimens, many of which 
are plainly beach-worn, and in the
