From what has already preceded, 
and from the large number of sections 
which I have examined, I think there 
can be no doubt 1) that the calceo-cuti- 
cular glands are quite uniform through- 
out, and offer no grounds whatever 
for the belief that they are directly 
connected with anything else; 2) that 
there is no hypodermis, and therefore 
nothing else for them to be connected 
with. It seems also, both from his figure 
and text, that Claparéde was likewise 
misled in supposing the calceo-cuticu- 
lar glands to be simply the ducts of the 
couche en piliers — which my method 
of staining shows to be perfectly distinct. 
With reference to the supposed 
cellular structure of the calceo-cuticu- 
lar glands, and also of the cells of the 
hypodermis, I have not been able to 
detect even the »signs« of it that Cla- 
parede states he distinguished. It 
would be interesting to make it out, 
but at the same time there is, in my 
opinion, no histological evidence of its 
existence. I may mention that it is 
some-times difficult to get the calceo- 
cuticular glands wellisolated on account 
of the external occurrence of large numbers of pigment granules. 
Below the calceo-cuticular glands, and in part underlying them, 
there is a second series of glands, the couche en piliers as they are
