hard gizzard, and that it was probably a coriaceous one; if so, 
I am wrong, as in the only live specimen I have since met 
with, I saw it, though it is so minute as to be little more than 
a pin’s point ; it appeared to have the aspect of a denticulated 
yellow lmgual riband, doubled up in two faces on a minute 
cylinder : I could not detect the third plate ; but as I removed 
the mass from the stomach, not the head, and from its com- 
plete similarity externally with its congener, I cannot doubt 
that the usual trifid gizzard of the race exists. The mouth is 
as in the B. catena, and the part of the upper disk imme- 
diately above it escapes from the general cloud colour in being 
white. This animal inhabits with the B. catena, but is a 
smaller species, and very free in showing the organs that are 
visible. I have omitted to say that the eyes and tentacula 
are altogether wanting. Long. ;3,, lat. et alt. =; uncie.

This species was discovered by us twenty years ago, but, 
though sedulously looked for, we have not seen it since, and 
can only refer to our original account of it in the ‘ Zoological 
Journal.’

The species not particularly enumerated above will now be 
mentioned. The Bulla lignaria has frequently been received 
fresh, though not alive, from the Plymouth grounds; the 
animal does not differ anatomically from the four we have 
described. The B. Cranchit has been sparmgly obtained in
