826 ITHE AMERICAN NATURALIST. [Vor. XXXIV. 
fished from a depth of thirty fathoms. After this preliminary we 
are prepared for the statement that the Z7Ze/;s in its search for fishes 
obtained incidentally forty-nine species of Decapoda and Stomato- 
poda, of which twenty-one are additions to the fauna and ten are 
new. These last are Pugettia mosaica, Chlorinoides waitei, Parami- 
thrax tuberculatus, Pilumnus australis, Paguristes tuberculatus, Sym- 
pagurus diogenes, Glaucothoé hexagonata, Porcellano-pagurus tridenta- 
tus, Galathea (sp.?), and Arctus crenatus. The new species, as well 
as some of the old ones, are fully described, and illustrated by 
photographs and outline drawings. Among the most notable of 
the other additions to the fauna is Pseudosguilia stylifera (Milne- 
Edwards), which was known only from Chile and southern Cali- 
fornia. This species, by the way, is entitled to a new name, being 
different from Sguilla stylifera of Lamarck, which Dr. Bigelow con- 
siders synonymous with 2seudosqui//a ciliata (Fabricius?) Miers. It 
is perhaps not remarkable that generic names that have been accepted 
for fifty or a hundred years, like Arctus, Eupagurus, and Squilla, 
should still be adhered to, though proven untenable. 
The Temple Primers, which are intended to give condensed infor- 
mation on great subjects, open with a volume on Some Problems of 
the Day in Natural Science: An Introduction. About half the book 
is given to first principles, including the definition, aim, and bound- : 
aries of science, the relations of science to philosophy, the senses as 
agents of the mind and their extension by artificial aids, the classifi- 
cation of the sciences, and the history and method of science. The 
remainder of the book is devoted to certain scientific problems of the 
day, such as the age of the earth, the ultimate constitution of matter, 
the origin of species, the coagulation of the blood, the function of 
nerve cells, and microphytology. In such restricted space so many 
problems can be touched on only superficially, and herein lies the 
chief defect of the volume. The book is neither better nor worse 
than its kind, but one is forced to ask why the impossible should be 
attempted. P.
