cloaca of the female, containing zodsperms. Internal fertilization is 
therefore proven for these forms 
A spermatheca occurs in Spelerpes; in the single specimen examined 
(taken in the fall) no zodsperms were contained. 
In Necturus, Diemyctylus and Amblystoma, there are several tubules 
or spermathecas opening upon the cloacal epithelium, which serve as 
reservoirs for the semen. 
In Desmognathus, Plethodon and Spelerpes, there is a single mesal 
spermatheca. 
The condition in Spelerpes would seem to indicate that the organ in 
these latter genera equals the group of tubules found in the first genera 
plus and exaggerated and modified depression of the cloacal epithelium, 
such as occurs in Amblystoma. 
2. No gland-like structures in addition to the spermatheca occur in 
the female of Plethodon and Desmognathus. 
3. In all the remaining genera a ventral cloacal gland is present. 
4. In Amblystoma, Spelerpes and Necturus, in addition to the sper- 
matheca tubules, other tubules occur on the dorsal side of the cloaca. 
5. The secretion of the cloacal glands is employed at the time of 
ovulation. 
6. The three glands of the male recognized in the Triton, the cloacal, 
abdominal and pelvic, occur and are well developed in the five genera 
examined. This suggests that by all of these spermatophores are de- 
posited. 
7. A résumé of the literature and foregoing facts points to a uniform 
mode of mating and fertilization in all urodeles. 
8. Dorsal and ventral ciliated tracts occur in the male of all the 
genera examined. Cilia in the cloaca of the female were detected only 
in Amblystoma and Plethodon glutinosus, where the tract was not as 
extensive as in the male. (Proceeds. Amer. Microscop. Soc., Vol. 
XVII, 1895.) 
Zoological News.—A second species has been added to the genus 
Opletharaaraie founded by Verrill to receive a West Indian species 
named O. agassizi. The new acquisition was obtained by a Misaki 
fisherman with a hook at a depth of about 25 fathoms in Iagami Bay, 
Japan. It is described and figured by Dr. Ijima and S. Ikeda under 
the name O. depressa. (Journ. Coll. Sci. Imp. Univ. of Japan, Vol. 
VIII, Pt. 2, Tokyo, 1895.) This genus is characterized by the fact 
that the alimentary canal passes directly through the body, instead of 
iy oe
