118 THE 4ZOOLOGIST. 
Duckworth has marshalled in small compass all the finds relating 
to the early days of our genus—even supposing that in the time 
to come only one genus will be recognized. Three divisions can 
now be formulated as expressed by the author :-— 
Group I. Early ancestral forms. Ex. gr. H. heidelbergensis. 
Group II. 
Subdivision A. Homo prinugenius. Ex. gr. La Chapelle. 
H. Fossiuis. Hx. gr. 
Subdivision B. H. recens; with vaveties| Galley Hill. 
H. sapiens. 
The concluding paragraph is to the point:—‘“‘ If progress 
since the foundations were laid by the giant workers of half a 
century ago appears slow and the advance negligible, let the 
extension of our recognition of such influences and possibilities 
be taken into account. The extraordinarily fruitful results of 
excavations during the last ten years may challenge comparison 
with those of any other period of similar duration.” We may 
be on the eve of finding further remains which may largely 
qualify our previous conclusions on prehistoric man. 

Butterfly-hunting in many Lands. By Groree B. Lonestarr, 
M.A., M.D., &c. Longmans, Green & Co. 
Dr. LonestarrF is a great lover of entomology and an ardent 
collector of insects in the field; he has seized every opportunity 
to follow his favourite pursuit; he made the best of his possi- 
bilities when attending the meeting of the British Association 
in South Africa, and also during several tours made in various 
tropical and subtropical countries; the results and itinerary 
form the substance of this somewhat massive but interesting 
volume. Some of the chapters are reprints of papers published 
by the author in the ‘Transactions’ of the Entomological 
Society of London, and have been revised and enlarged, and 
the introduction and the chapter devoted to ‘“‘Some Early 
Reminiscences ”’ recall old scenes and old friends to many of us. 
Dr. Longstaff is an evolutionist who thoroughly accepts the 
doctrine of the ‘‘ survival of the fittest,’ and may be described 
as a moderate ‘‘ natural selectionist.”” One of the most inte- 
resting observations is his witness to the universality of the 
gesture language in mankind, long since so ably stated by
