No. 409.] REVIEWS OF RECENT LITERATURE, 63 
Different kinds of birds varied very greatly in number and type of 
parasites sheltered, and forms common in the one would be entirely 
absent or rare in the other. Full results of the examinations are 
given in a series of tables which show the number, condition, loca- 
tion, and name of the parasites collected and the date, locality, col- 
lector, and name of the host. The second half of the paper is 
devoted to an anatomical description and discussion of some of the 
less known cestodes found. The descriptions are full and contain 
many new points which are well illustrated on the plates. One new 
species, Hymenolepis tetraonis, was discovered in the quail, in which 
it is apparently very common. H. B. W. 
Revision of the Ticks. — Of this work by Neumann,’ a third part 
has just appeared. It covers the tribe of the Ixodz, including the 
eyeless genera Ixodes, Haemalastor, and Aponomma, and the genera 
Hyalomma and Amblyomma which possess eyes. Analytical keys 
for each genus, based on the characters of the male, of the female, 
and of the nymph, and full bibliographic references make the work a 
mine of information. Inasmuch as the ticks from the collection of 
the Bureau of Animal Industry were placed in the hands of the 
author for this revision, it has a peculiar value for American students; 
this usefulness is greatly enhanced by the full references given under 
geographical distribution to the individual states of the Union from 
which the specimens have been collected. With delicate courtesy 
the names of new species taken from labels written by the late George 
Marx are used and the species credited to that author; many of his 
drawings are also incorporated in the article, although for the text 
Professor Neumann is alone responsible. The most important 
change in the nomenclature of American forms is the suppression of 
. Ixodes unipunctata Packard, the Lone Star Tick, as synonymous with 
Amblyomma americanum Koch. The illustrations of the revision are 
good, the text clear and concise, and the work is evidently carefully 
done, making it altogether the most important contribution in this 
group since the monograph of Koch. A fourth part to include 
additions, corrections, and general considerations of a taxonomic 
character to conclude the work will appear soon. H. B. W. 
The Coccidze of Brazil. — As recently as 1897 Dr. H. von Ihering 
catalogued the Coccidze of Brazil, but he was able to enumerate
