On the 9th no apparent change had taken place. On the 
11th the speck had enlarged, but was too transparent to 
admit of its form being distinguished ; upon moving the speck 
it fell out of its place. 
On the 12th the embryo was indistinctly seen. 
On the 15th the embryo filled \ part of the egg, but the 
different parts were still indistinct. 
On the 18th the body of the embryo had become larger, 
and the covering thicker. 
On the 19th, the coverings or shells of all the eggs were 
more or less dissolved, so much so that Mr. Hunter thought 
all the eggs were rotting, and the whole brood of young 
would be lost. 
On the 20th, the young were hatched, and the shells com- 
pletely formed. 
On the 23d, when the young snails were put in water, 
their bodies came out of the shell, as in full grown snails. 
On the 24th, they all deserted their nests. 
The specimens of the sepia found in the argonaut shell, 
which was caught by Mr. Cranch, in this expedition to the 
Congo, had deposited some of its eggs in the involuted part of 
the shell, and the animal being fortunately caught in the shell, 
identified the eggs to belong to it ; (PL XIV.) they are united 
together by pedicles, like the eggs of the sepia octopus, and in 
all other respects resemble them ; they differ from those of 
the helix janthina and the other vermes testacea, that live in 
water, in having no camerated nidus, and in having a very 
large yelk to supply the young with nourishment, after they 
are hatched. 
Upon these grounds, this animal must be resolved into a 
species of sepia, an animal which has no external shell.
