var. /3, has the right lip plaited within, 
var. y, spire and beak produced more than 
in var. a ; upper part of each volution 
rather concave. 
Syn. Murex Pyrus. Brander, f. 52 53. 
var. ^ spire much produced ; whorls sub- 
ventricose, with a deep obtuse canal 
around their upper parts. 
The type of this species is a short ventricose shell, 
with an acute, mucronated spire, and without the least 
concavity upon the upper parts of the whorls (fig. 4.) 
the left lip is thick, especially towards the upper part, 
raid there is also a protuberance inside, near the top of 
the right lip, so that a narrow canal is formed at the 
upper angle of the mouth ; the beak is a little curved, 
and rather broad. The variety o at first sight has the 
aspect of a very distinct species, as it is much longer : 
it has a considerable obtuse ridge near the upper edge 
of each turn, produced by an (increased thickness of the 
shell at that part, from whence results a flatness of the 
body of the shell, and an obtuse canal around the spire;
