large tubes which are bent upon themselves. These open posteriorly into 
two ducts that run forward beneath the intestine. The anterior half of 
each of them is double. In the fourth segment they unite into a short 
tube on the side of the body. This communieates with a transverse tube 
into which the seminal vesicles open, and which opens to the exterior 
by two openings. 
The spermatozoa are pod-like. —F. C. Kenyon. 
Thysanura from the Cave of Central France.—M. R. 
Moniez describes three new species of Thysanoures from the grotto of 
Dargilan in the Department of Lozére, France. The first, Qampodea 
dargilani, appears to be the third of a series of forms adapted progres- 
sively for a life in darkness. That is, the characters of C. staphylinus, 
the type of the genus living in open air, are more accentuated in C. 
eoopei, a cave form, and are carried to an extreme in C. dargilani. 
The second, Sira eavernarum, is white, covered with transparent scales, 
and is entirely blind. The third, Lipura cirrigera, is characterized by
