anatomy and physiology of the eye; the second part, of nine volumes 
on the pathology and therapeutics of this organ. The large number 
and high standing of the collaborators give promise of a speedy and 
satisfactory performance of the work. Volumes, or parts of volumes, 
will be sold separately. 
The rich collection of cetacean embryos made some years ago by 
Professor Kiikenthal is being put to good use, as shown by the last 
number of /enazsche Zeitschrift (Bd. XXXII, Heft 1 and 2), which is 
made up of the following articles based on a study of this material ; 
F. Jungklaus, The Stomach of the Cetaceans‘; O. Müller, Researches 
on the Alterations which the Mammalian Respiratory Organs have 
undergone in Adaptation to Water Life; W. Daudt, Contributions to 
our Knowledge of the Urogenital Apparatus of the Cetaceans. 
In the Festschrift til Kong Oskar II, Dr. Guldberg publishes the 
results of his investigation on the asymmetry of the higher vertebrates. 
Osteometric statistics, as well as data from the weight of the muscu- 
lature of opposite sides of the body, indicate the occurrence of a 
morphological asymmetry in birds, in many mammals, and in man. 
This asymmetry is least at birth and increases with age; it finds its 
physiological expression in the tendency to move in a circle. Com- 
pensated and crossed asymmetry are of frequent occurrence. 
The Organs of Respiration of the Oniscidz are described by Pro- 
fessor J. H. Stoller in Zoologica. He finds the gills to be homologous 
with those of aquatic isopods, but adapted to breathing atmospheric 
air. A respiratory tree, resembling the trachez of insects, is bathed 
by the blood which is brought to the gills. Adaptations for the pre- 
vention of the desiccation of the blood are found, and there is no 
mechanism for forcible inspiration and expiration of the air. 
The Parasites of the Flamingo have recently been studied in Tunis 
by Dr. M. Lühe (Situngsb. Pr. Akad. Wiss., Vol. XL, pp. 619-628), who 
has found Zenia lamelligera Owen, which Diamare made the type of 
a new genus, Amabilia. Three species of Drepanodotznia were also 
found: Tenia liguloides Gerv., and its immature form, which proved 
to be identical with 7. Caroli Par., and 7: megalorchis and T. isch- 
norhynchan. sp. In the same host Monostoma attenuatum Rud. was 
present in the cecum, and the new species Distomum michropharyn- 
- geum in the gall bladder, and Echinostomum thenicopteri in the small 
intestine. From the civet-cat two new forms of Dipylidium, D. “7 
seriale and D. monoophorum, were secured.
