volutions, though the whole of the specimen has obviously 
been subjected to abnormal and lateral compression. Its 
surface markings consist of a broad, flat and nearly central, 
spiral slit-band, to which the growth lines on each side con- 
verge obliquely backward. Apart from its abnormal com- 
pression, this specimen is essentially similar in size, shape 
and surface markings, to the specimens from Gamache Bay, 
Anticosti, which Mr. Billings refers to his J. teretiformis 
(op. cit., p. 55) and upon which he bases the statement that 
‘this species has a wide flat band about the middle of the 
whorl and appears to be a large variety of M. bellicincta, 
Hall.” 
It would thus appear that WM. major, Hall, and M. tereti- 
formis, Billings, are most probably synonymous, the former 
having been based upon very imperfect casts of the interior 
or the shell, and the latter upon more perfect and at least 
partially testiferous specimens. The name teretiformis is 
here used ina varietal sense, on the ground that it was the 
first prefixed to a sufficiently accurate diagnosis of the 
characters of the shell.
