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

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

 latter varietj^ 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- 

 state of the species. General length about Ifths inch ; breadth 

 about fths.

It is not without doubt that I have separated this shell specifically 

 from the last ; but in addition to the difference of shape, the colour- 

 ing matter, here again, instead of stopping short just above the outer 

 lip, where it begins to expand, as is the case Avith Bul. fictilis, is 

 carried on and over the external expanse of the outer lip, so as to 

 constitute a coloured rim on its lower external edge. In other re- 

 spects there is much similarity between the two. General length 

 about 1| inch ; breadth across body-whorl rather more than half an 

 inch.— W. J. B.
