CLAUSILIA. 



Original description: " Cl. testa stramineo-albida,subf usiforme- 

 turrita, apice attenuata, aperturam versus subaugustata, non 

 rimata ; aufractibus 10-12, paulum eonvexiusculis, sutura profunda 

 siinplici junctis, transversim oblique capillaceo striolatis ; apertura 

 rectiuscula, sub-rectangulari, antice subrotundata, inarginibus 

 inodice dilatatis et incrassatis, labio breviter libero, fere recto, 

 biplicato, plica antica (seu int'eriore) valde oblique intrante; plicis 

 palatalibus quinque, fere aequidistantibus et inter se parallelis, 

 supera longissima, caeteris subaequalibus.

" This is the new Arakan species to which Mr. Blauford alludes 

 at p. 205, when speaking of Cl. monticola ; it differs from this 

 last by its more fusiform instead of conoidally turreted shape, its 

 thinner texture, larger aperture and somewhat differently arranged 

 palatal folds. I have given illustrations of a shorter form with 

 ten whorls, and of another with twelve whorls ; the former is a 

 single specimen from the hills S.E. of Akyab, the other was 

 collected by Mr. Theobald at Mai-i, in the Sandoway district. 

 These two forms represent the extreme variations which were 

 noticed among a large number of specimens." (Stoliczka.) 



Two shells, from Mai-i, in the Theobald collection, measure 

 20x4 mm., and distinctly show the five palatal plicae indicated in 

 the diagnosis.

Shell rimate, fusiform, fuscous corneous, rather solid, opaque, 

 finely striate, closely ribbed behind the aperture on the last whorl, 

 some indistinct, very fine spirals perceptible on the later whorls. 

 Spire turreted, the sides slightly concave ; apex slightly obtuse ; 

 suture shallow, especially on the later whorls. Whorls 11, the

earlier slightly convex, the later ones flattened, the last but little 

 narrower than the penultimate, with a shallow furrow below the 

 lower palatal plica behind the peristome and gibbous around the 

 umbilical slit. Aperture a little oblique, subovate. Parietal folds 

 rather close together, upper not interrupted, lower deflexed 

 towards the columella and descending with the columellar margin. 

 Palatal plicae three, rather near the aperture, the upper rather
