CLAUSILIA. 311 



Blanford in his diagnosis only mentions two palatal folds, but I 

 have found a third, wliich, however, is not visible without opening 

 the shell. 



275. Clausula biirmanica, sp. u. 



Shell riiuate, fusiform, fuscous, translucent, very closely in- 

 vested with fine wavy stria?, traversed by rather irregular, 

 somewhat indistinct spirals. Spire turreted, gradually attenuated, 

 tlie sides not concave ; apex acute ; suture impressed. Whorls 11|, 

 convex, last scarcely narrower than penultimate, not compressed 

 below upper palatal plica. Aperture vertical, snbquadrate. 

 Parietal folds rather distant, the upper not interrupted, lower 

 rather elongated before entering. Palatal plica? three, upper long, 

 parallel with the suture ; the other two curved, almost meeting 

 posteriorly, rather distant, one being close to the upper plica, 

 the other nearer the aperture. Peristome solute, the margins 

 expanded and reliexed, outer margin descending obliquely. 



Long. 21, diam. 4 mm.

Fig. lOG. — Clausilia hurmanica. 



The specimen upon which this new species is based occurred 

 with two shells of Clausilia theohaldi, from which it differs by the 

 much more wavy, closer, and finer striae, the presence of spirals, 

 and the snbquadrate aperture ; the two lower palatal plicae, 

 moreover, instead of being straight and rather close together, as 

 in tlieohaldi, are rather distant and curved, their posterior termina- 

 tions neai'ly meeting, as seen in fig. 106 6, which shows the inside 

 of the last whorl witb the palatal plicae in situ ; finally, the last 

 whorl is not compressed below tlie upper palatal plica, the parietal 

 folds are more distant, the upper is not interrupted and the lower 

 longer before entering, proceeding horizontally. 



The Hungerford collection in the British Museum contains tw o 

 specimens from Bhamo, which 1 also refer to this new species ; 

 they possess twelve whorls.
