782 THE AMERICAN NATURALIST. [VOL XXXV 
In the Abhandlungen der Senchenbergischen Naturforschenden Gesell- 
schaft of Frankfurt (Vol. XXV, No. 2), Dr. Steindachner gives an 
account of the fishes collected by Dr. Kükenthal in Molucca and 
Borneo. Two hundred and eight species are enumerated, six of 
them new, most of these being well figured. 
In the Records of Australian Museum (Vol. IV, No. 1), Mr. E. R. 
Waite discovers that the sharks of the genera Hemiscyllium and 
Chiloscyllium bring forth their young alive. He therefore very 
properly separates these genera from the Scylliorhinidz as a distinct 
family, Hemiscylliide. The genus Orectolobus (Crossorhinus) is 
also viviparous, and is recognized as a distinct family, Orectolobidz. 
A figure is given of Hemiscyllium modestum, and also of the Austra- 
lian dogfish, Sgualus megalops, a species which has a very close 
relative in Japan. 
As fishes of Lord Howe’s Island, Mr. Waite figures Upeneus pleu- 
rostigma, Apogon norfolcensis, Iniistius cacatua, Chatodon tricinctus, 
and Monacanthius homensis. We may note that the deep green color 
of the teeth of Pseudoscarus guacamaia and related species is not the 
result of staining through the food. It is inborn, unvarying, and a 
result of distinct specialization. DS 
An Elementary Book on Lepidoptera. — This is really an excel- 
lent book, both in conception and in execution. Reversing the 
order of her title, Miss Dickerson deals in* Part I with the butter- 
flies. The monarch Danais archippus holds the place of honor, 
and its life history and structural characters are given accurately 
and with sufficient detail ; the other species, twelve in number, with 
the exception of two swallowtails, Papilios, a white, Pieris, and a 
sulphur, Colias, are all closely allied nymphalids. 
In Part II Callosamia promethea is made the starting point, and 
the twenty and more species that follow are Bombyces, sensu lat., 
and Sphinges. : 
The treatment in both these parts is so happy that the omission 
. of an adequate account of the life history of a blue, Lyczna, and of 
a skipper, hesperid, among the butterflies, and of two or more of the 
lower moths, is especially regrettable. i 
Part III is divided between a chapter on relationship, showing 
classification and ancestry of moths and butterflies, and practi 
suggestions how to collect, keep, and study butterflies and moths.
