RECENT LITERATURE. 
The Apodidez.'—This, one of the latest of the “ Nature Series,” 
is not up to its predecessors either in accuracy of statement or sug- 
gestiveness of matter. The author, starting off with the intention of 
working up the comparative anatomy of this family of phyllopod crus- 
tacea, has been led to regard them as all-important in phylogenetic 
speculations, but, unfortunately, the good points of his volume are not 
original, while the original portions cannot be praised. Thus the cen- 
tral position of the Phyllopods in the Crustacean branch was recog- 
nized long ago, while the comparison of the foot of the Apus with the 
parapodum of a Polychzte worm was made long before Bernard entered 
the field of zoology. On the other hand the special studies of Mr. 
Bernard have led him to regard the differences between the annelids 
and Apus as of extremely minor importance. All you have to do, 
says he in effect, is to bend the anterior end of a carnivorous annelid 
back upon itself to produce this portion of Apus, and the thing is 
done. Resemblances are magnified and differences are minimized or 
ignored, and presto! Apus is the all-important arthropod. The name 
of Macmillan & Co. is so uniformly associated with only first-class 
works that we were surprised to see it on the present volume. 
Darwin, and After Darwin; I, The Darwinian Theory, 
by Grorce Jonn Romanes.’—Romanes has devoted the best years 
of his’ life to the defence of the evolutionary faith and to making 
himself acquainted with, advocating, and extending Darwin’s ideas. 
The present work consists of two volumes, viz., “The Darwinian 
Theory,” and “ Post-Darwinian Questions.” The latter, soon to be 
issued, is to treat of heredity, utility, isolation, etc., which have 
become prominent since the death of Darwin. The former is a 
systematic exposition of the Darwinism of Darwin. It gives a 
résumé of the evidence, as it is known at present from class- 
ification, Morphology, Embryology, Paleontology, and Geographical 
Distribution, and includes a full discussion of the Theories of Natural 
and of Sexual Selection. It is a neat volume of 460 pages, fully
