the pulli, whilst Kellia suborbicularis requires the tube to be 
closed, as it is for some time a nidus for the full development of 
the testaceous young. 
I am at this moment enabled to add, that I have just opened 
a very large Kellia suborbicularis having the contents of the ova- 
rium converted from its usual ova-like aspect into many thousands 
of completely testaceous young further to be developed before 
exclusion from the anomalous oviduct. 
The reason why this state of the ova has so often escaped de- 
tection is, that the ovarium has not been examined at the genial 
season. To see it as I have stated; we must attend to the im- 
junction of C. Lucretius— 
“ JEtheris et terree genitabile querere tempus.” 
I have on a card many thousands of the testaceous young taken 
from the matrix of the individual above mentioned, a part of 
which I shall have much pleasure in forwarding to any gentleman 
who may desire it. 
It gives me great pleasure that the question of the use of the 
anomalous tubes is at length set at rest, and the discussion as to 
them between Mr. Alder and myself is ended.
