but for this success he paid with his life.” 
The volume contains an elaborate memoir by Mr. J. Graham 
Kerr on “‘ The Development of Polypterus senegalus,” and another 
by Mr. Richard Assheton on ‘‘ The Development of Gymnarchus 
niloticus; Mr. Edward T. Browne writes on ‘‘The Freshwater 
Medusa Limnocnida tanganice discovered by Budgett in the River 
Niger,’ and Mr. Edward J. Bles on ‘‘ Anuran Development.” 
The various scientific papers of the deceased biologist are also 
reprinted, and a beautifully illustrated volume constitutes both 
a personal testimonial and a no mean contribution to biological 
science. 
A Guide to the Study of Australian Butterflies. By W. J. 
Ratnsow, F.L.S., &e. T.C. Lothian, Melbourne. 
Tuts book is an introduction to a knowledge of the Australian 
Rhopalocera, and is confined to those species ‘‘ of which some- 
thing is known of their life-history.’”’ It is therefore biological 
and bionomical so far as it goes, and ‘‘ no previous knowledge on 
the part of the reader has been presupposed.’ As an intro- 
duction to a most interesting lepidopterous fauna, Mr. Rainbow 
has achieved success—he has created an interest in these butter- 
flies, and in giving the life-histories of a number of species he 
has disclosed the method to be pursued in investigating those of 
the many species untouched in his volume. Itis thus an incite- 
ment for future work beyond the mere accumulation and naming 
of species for cabinet adornment. Typical species of the principal 
families and subfamilies are well figured, and, what is more, 
many ova, larve, and pupe. 
As regards the terminology used, some criticism is allowable. 
Thus Mr. Rainbow prefers the generic name Danaus to that of 
Danais, but still retains the name Danaine for the subfamily. 
As this is founded on Danais, one change must necessitate a 
constructive change in the other. Again in chap. v., devoted to 
the ‘‘ Blues and Coppers,” he has substituted the name Lycinide 
for Lycenide, but in previous pages and on five occasions he 
has referred to the family as Lycenide, a course likely to pro-
