M. pungens. Brander , f. 82. 
Spec. Char. Oblong, varicose ; each varix foli- 
ated, and produced above in a recurved tube ; 
aperture obovate, entire ; beak nearly straight, 
closed. 
By no means a handsome shell, although remarkable ; 
the varices, or ribs, are thick and clumsy ; each has a 
sinuated thin appendage at the back of it, and a large 
arched tube at the upper part : the aperture is perfectly 
entire, the lips being joined all round : outside the right 
lip are four or five sinuated fimbriae, more or less distinct 
in different individuals : the beak is broad, and in old 
shells is often double or triple, the earlier formed ones 
remaining uncovered. The width of the shell in the 
middle is about half the length. 
I have met w ith two specimens of this found in Bar- 
ton Cliff ; they were presented to me by Mr. Bullock : in 
one of them the fimbriae near the aperture are very 
obscure : allowing that they may sometimes be entirely 
wanting, there would not remain a shadow of difference 
between these shells and Brocchi’s figure : Brocchi ob- 
serves, that his shell is variable. Brander’s fig. 82, 
seems to have been intended for this also, although in 
Dr. Solander’s description it is not distinguished from 
M. pungens, fig. 81.
