injurious they certainly are to flour stores. ‘These larve swarm 
in all places where flour and meal are kept, and often do great 
damage to biscuits, especially those which are taken to sea. 
A Zoological Atlas (including Comparative Anatomy); with Prac- 
tical Directions and Explanatory Text. For the use of 
Students. 249 coloured figures and diagrams. By D. 
M‘Atpine, F.C.S., Lecturer on Biology and Natural 
History, Edinburgh. (Jnvertebrata.) Edinburgh and 
London: W. & A. K. Johnston. 1881. 
‘HE first part of this Atlas, containing the Vertebrata has 
already been noticed in ‘The Zoologist’ (anted p. 392). The 
second part just published deals with the Invertebrata, and 
contains carefully drawn figures of the external and internal 
structure. ‘This is so much more varied than is the case with 
the Vertebrates, that the number of typical forms is necessarily 
much greater. To keep the size of the work within due limits 
the author has been obliged to make a selection, and has given 
a preference to such genera as are required for the Practical 
Examination of the University of London. In that examination 
not only has the candidate to dissect specimens placed before 
him, but also to examine and describe prepared specimens, and 
the first four plates in this Atlas may be regarded as preliminary 
exercise in seeing and describing. ‘They are introduced to show 
how the lower forms may be studied, and how by the use of what 
the author calls “ Life-History Diagnoses” the student may take 
in at a glance the chief features of their life. 
As regards the explanatory text, the brief introductory 
description of the animal usually gives those characters which 
are best observed in the living state, and which show its relations 
to its surroundings, while the remainder of the text describes the 
figures, dealing with the various parts of the animal in detail. . 
The clearness with which these details have been drawn renders 
the Atlas on the whole a useful aid to practical anatomy.
