This species may eventually prove but a large and fine 
variety of B. japonica, A. Adams ; but at present I distinguish 
it with a separate name, since there are several differences 
which may be regarded as specific. The whorls are only 
slightly angulated in the middle by the keel which encircles 
them at that part; and this keel is undulated, a character not 
assigned to B. japonica; the red spotting on the keels is also 
absent in that species ; and the colour of the epidermis is differ- 
ent. At the base of the cauda in the present species there is 
a largish excavation; but I am inclined to attribute it to a 
repaired injury.

I give these measurements, as they are omitted by Mr. A.

as of no importance.
