But we then fall back upon the law developed by Max Schultze 
for Nais proboscidea. We fall back upon it without implying any 
other generation than that constituting the normal and continuous 
mode of growth of the Annelide in question. We therefore think 
that we may express the opinion that in the Naides there are not 
two modes of agamic reproduction, one by scissiparity, the other by 
gemmation. There is nothing but scissiparity. 
The gemmation observed by the authors who have already treated 
this vagin cd appears to us to be nothing Lim the l : 
menon of growth of the individusl. Hence no longer meet with 
it in the poete rior portion of the body of adult individuals. It is 
only when it has brought each individual produced by B 
to a certain size that a new division takes place. s fresh div 
sion may appear before or after the complete separation of the pri 
mary individuals. This, according to us, is the sole difference.—

On Edible Bull-frogs. 
** Bull-frogs are eaten in Philadelphia. I saw laid out on the 
counter an edible which somewhat resembled à fried sole. I observed 
several persons devouring them greedily, and. on inquiring what 
they were, learned to my extreme horror that they were bull- -frogs, 
gutted, slit T and fried in eggs anå bread-crumbs. They are 
also to be had at railway nations "—H. Phillips, Musical and Per- 
sonal Recollections, 1864, p. 122.

Echinospongia australis. 
Hab. Nichol’s Bay, West Australia. 
This remarkable Sponge was discovered by Mr. Clifton, who has 
kindly sent a specimen to the British Museum. 
Dr. Bowerbank has figured the spicules of a reticulated ee 
from the same locality, which I have called Axos Cliftoni; but in i 
the spicules are formed of two flat three-rayed stars, placed one on 
the other so that the rays alternate; they are aims dentate at 
their extremity.
