specimens of Necturus, Desmognathus and Diemyctylus were taken from 
January to April and none were examined after spawning. Specimens 
of Amblystoma were studied shortly before and immediately after ovula- 
tion, and in August and December. In all the species cilia were found 
only in the adult female. They occurred constantly upon the hepatic 
ligament, the ventral wall of the body cavity, the membranes near the 
mouths of the oviducts and upon the serosa of the liver. In Amblys- 
toma cilia were also found upon the mesoarium and the membranes 
supporting the oviducts. Some of the adult female Necturi possessed 
cilia also upon the cephalic part of the dorsal wall of the body cavity. 
The ciliated cells occured either singly or in groups. They were most 
numerous near the mouths of the oviducts. It was found that the 
direction of the current produced by the cilia was towards and into the 
mouths of the oviducts. This and the fact that cilia are present upon 
the peritoneum of the adult female only would seem to strengthen the 
theory that the ova when set free in the body ies are as 104 ee by 
means of cilia into the oviducts.—IsaBeLvA M. Gre 
The Penial Structure of the Sauria.—In the Proceedings of 
the Philadelphia Academy for August and September I have published 
a paper on this subject, which gives the results of an investigation into 
the anatomy of the hemipenes of lizards. Very little attention has been 
given to the subject hitherto, and our knowledge up to 1856! is thus 
summarized by Stannius: “ A duplication or bifurcation of each organ 
is present in Lacerta and in Platydactylus guttatus. The copulatory 
organs of the Chamzeleonide are distinguished by their shortness. In 
various Varanidæ which have been investigated the internal cavity 
(external when protruded) has-transverse concentric folds. A fissure 
interrupts these folds so that they are not complete annuli. The 
— is acuminate and expands at the base, forming a kind of 
glans.’ 
In 1870’ J. E. Gray describes and figure this organ of Varanus her- 
aldicus, giving the best illustration that I know of. In 1886 Wieder- 
sheim (Lehrbuch der Vergl Anat. Wirbelth.) describes and figures 
this organ in Lacerta. Besides these references I know of nothing 
later. 
As was to have been anticipated, I have found these organs to corre- 
spond with the rest of the structure, and to furnish invaluable aids to 
the determination of affinities among the Sauria. Reference to them
