Of this species 1 have seen two specimens in the Cuming 

 collection, bearing Pfeift'er's own label. S. baconi is very fragile 

 and thin, whitish corneous, and may be regarded as intermediate 

 in character between S. semiserica and S. daucina, but some 

 specimens in the Blanford collection are somewhat amber coloured 

 and, although possessing 2.^ whorls, only measure: length 14, 

 diam. 9 mm. In the Beddome collection are some shells trom 

 South Canara.

 The present species is readily distinguished from its nearest 

 allies bv the slightly indexed outer margin of the peristome. In 

 the Cuming collection are four shells, labelled by Pfeiffer himself, 

 none of which, however, exceeds 9 mm. in diameter. The specimen 

 figured by llanley and Theobald has been presented to the National 

 Collection by Mr. Harvey.
