 p. 160. 



A beautiful species, known by its light buff color, with fewer 

 spiral brown bands than the majority of banded Sphcerospira. 



It is very numerous, according to Brazier, on the trunks of the 

 native fig trees. 



An elevated form is figured on pi. 40, fig. 92. 



H. CROFTONI Cox. PL 21, fig. 52. 



Shell imperforate, globose-conoidal ; buff, with two broad dark 

 chestnut zones above, one just under the suture, the other a short dis- 

 tance below it, fusing with it on the latter part of the body-whorl, and 

 generally a circular umbilical dark patch, the intervening space with 

 several brown lines. Aperture of a livid-whitish color inside, flesh- 

 colored or bluish-white on the broadly expanded lip, callus over the 

 umbilicus dark livid brown. 



Compact, solid; the ground-color is buff; suture edged by a 

 narrow white or buff line, bordered by a broad chestnut zone, 

 below which there is another broad zone, separated from the first 

 by a light space in which a brown line revolves. These two supra- 

 peripheral zones coalesce on the last third of the body-whorl, and 

 this part often is suffused with brown, all over the light buff ground. 

 There is usually a brown basal band or tract around the axis. The 

 spire is elevated, outlines convex; whorls 6? to 7, slightly convex, 

 the last deflexed in front, not impressed at the place of the closed 

 umbilicus. The aperture is broad, oblique ; the lip expanded, sub- 

 reflexed, dilated over and closing the umbilicus, passing into a glossy 

 wash of parietal callus, which is stained with brown around the axis.

Curiously intermediate between Coxi and Blomfieldi, decidedly 

 darker than the first (of which it should perhaps be considered a 

 color-variety) but not nearly so dark as the latter species. It is 

 very local in habitat. Found inside the hollow trunks of Quang- 

 dong trees.
