found below tlie periphery. Mr. Brazier, however, has described 

 one, V. Alisoni, as " smooth." I shall be glad to know whether in 

 reality minute spiral sculpture is altogether absent in that species.

 The subcarination near the periphery of the body-whorl men-

 by Martens.

There appears to me no difference between the V. suprafaseiata 

 of Tryon and this species, except that the former, judging by the 

 figure, seems rather broad. Possibly this may be an exaggera- 

 tion and incorrectly drawn ; for it is certainly broader than the 

 dimensions given in the text. 



Three specimens from Cleveland Bay, presented to the Museum 

 by Mr. Brazier, are remarkable on account of their bright olive- 

 green colour and the blackness of the transverse lines. Of these, 

 the three principal ones on the body-whorl occupy the positions 

 always observable in this species — namely, the lowermost being at 

 the periphery and terminating in front just above the aperture, the 

 uppermost one distant 2 to 3 millim. from the suture, and the 

 intermediate one more or less equidistant between the others. 

 Besides these, there are at times finer interjacent lines, which, 

 however, are more frequently above the uppermost, or between 

 that and the next beneath than between the latter and the lower- 

 most principal bands. The peristome in these three examples is 

 unusually stained with black.
