Some of the varieties of this fine shell, especially variety b, will 

 remind the observer, at first sight, of the species last described ; but 

 Mr. Cuming informs us that the animal is reddish brown, and, be- 

 sides other diff^erences in the shell, the colouring-matter, instead of 

 stopping short at that point of the body- whorl, just where the lip 

 begins to expand, is continued on to the very rim, which is in most 

 instances bordered with it ; nay, the colour generally becomes more 

 intense upon the upper part of the expansion. Varieties d. and e. 

 were found at Calapan; varieties c. and/, at Puerto Galero. The 

 latter variety has generally a chestnut oblique stripe or spot at the 

 bottom of the whorl and on the upper expansion of the outer lip, 

 continued from above the columella. Sometimes there is an obscure 

 line of a somewhat darker hue belting the body-whorl in this same 

 variety. 



This species varies a good deal in length and breadth. The 

 average length may be taken at about two inches, and the width 

 across the body- whorl at from more than an inch to |^ths of an inch.

In var. a. the dark ground-colour of the shell is striped, and pow- 

 dered, as it were, with the whitish epidermis; in var. b. this whitish 

 epidermis predominates, so that the longitudinal zebra-like stripes 

 arising from the exposure of the dark brown, but shining ground- 

 colour, are comparatively distinct. Var. d. seems to be the albino-
