A. and B. are semi-opaque, the opacity gradually diminishing to¬ 
wards 0., brown and roughened on the surface. 
C. is membranous, translucent, yellow, veined and blotched irregu¬

It must be observed that I have only seen eupronychia in fresh spe¬ 
cimens of the female, thus forming an apparent sexual distinction. As, 
however, these appendages are so very delicate, that the slightest fric¬ 
tion is sufficient to rupture them, I am not prepared to say that such is 
the case, until I have had an opportunity of examining some recently 
captured males.
