CLAUSILIA. 321 



seen a considerable series, but 1 have not observed the same 

 amount ot variation as in Clansilia gouUiana. Jt has close 

 atiinitj uith the latter, but may at once be distinguished bv the 

 more obtuse apex, the apical wl.orls being stouter and increasing 

 at once, not gradually as in r/ouldiana, the upper part of the 

 spire IS consequently more cylindrical and not concave. The 

 number of whorls ranges between 8i and 10, and the palatal 

 plicae vary in number from five to seven, the last being more 

 nearly vertical than in rjoiddiana. The shell is generally of more 

 solid texture, darker, and unicolorous, not whitish or pale 

 corneous, as in its ally, and the peristome dark. 

 1 u^^, ^i'? ^"oiing collection I found two shells from Tavoy 

 labelled by Pfeiffer, which are rufous corneous, with the (varly 

 Mhorls paler; one has 9i whorls, and measures 2G x (ro mm the 

 other has 10 whorls, and attains a length of 27-5 mm 'the 

 diameter being the same as in the first. Another tablet in the 

 Cuming collection bears three shells, also from Tavoy, which are 

 pale corneous Mith the peristome almost white, one 6f which has 

 10 whorls and measures 2Q x f> mm., but a second with 9 whorls 

 does not exceed 24-5 mm. in length, although its diameter is also 

 bmm. Ihe Eeddome collection contains four specimens, very 

 solid and dark chestnut in colour, with a dark fuscous peristome : 

 one of 81 whorls measures 26x7 mm., another of 9 whorls is 

 -/ X 7 mm., while the other two have each 9| whorls aud measure 

 respectively 28x7 and 30x6-5 mm. Lastly, a variety from 

 Zvvagabin in the Theobald collection is pale 'corneous and less 

 ventricose than the type, possesses 10 whorls and measures 

 2/ x 6 mm.
