but also a serpulid worm tube, a half cocoanut shell, and a broken 
glass tube were appropriated. Ocypoda occurs here in two species, 
one of which lives and burrows in the sand, the other inland. Three 
grapsids are found ; two Palæmonidæ, a Ligia, four Oniscidz, and 
one of the Armadillidiide. 
Recent Sporozoan Investigations.' — This pamphlet, which is a 
revision and expansion of the articles published in the Centra/blatt 
für Bakteriologie (Bde. XXVII and XXVIII), gives not only the 
most extensive, but also the fullest and most reliable, discussion of 
present knowledge on this group, which has been almost neglected 
until the appearance of recent studies on its structure and develop- 
ment. The chapters of Lühe's work take up the life history (1) of 
the Coccidia, (2) of the Hamosporidia (malarial parasites), (3) of 
the Gregarinida, Myxosporidia, and the little-known groups of Micro- 
sporidia, Sarcosporidia, and Haplosporidia. The first two sections 
are particularly complete and satisfactory, and it is hard to find 
omissions, while the discussion of the various authors cited is admi- 
rably fair. The comparative table of terms used by different writers 
in describing the development of Coccidia will prove very useful in 
view of the entire lack of uniformity as to terms employed, — a defect 
so universal that even successive publications of the same investigator 
differ in terminology. Much would be gained by the adoption of a 
uniform set of terms as advocated by Lühe, but unfortunately the 
papers which have appeared since his have added to the confusion 
by making further changes. 
The third chapter is the least satisfactory, probably, since the field 
covered by it is the least well known and is consequently most diffi- 
cult to bring into relation with the other groups. Furthermore, the 
introduction of numerous additions to the original articles, in the 
form of lengthy footnotes and appendices, makes the treatise difficult 
to use at some points; and yet the gain in accuracy compensates 
for the slight lack of clearness. 
In one point the work must be strongly criticised: the biblio- 
graphic methods employed are antiquated and cumbersome to an 
extent that interferes greatly with the clearness of the text. One 
may well wonder how the author could have done so well with such 
a confused system of reference, the same papers, 6g., Labbé, ** Sporo- 
zoa,” being referred to in three different literature lists by as many 
. different numbers. |
