Original description : " T. leviter rimata, fusiformis, solida, 

 conferiissime capillaceo-striata, sericea, rubicunda ; spira sursum 

 regulariter attenuata, apice alba, obtusula ; anfr. 11-11J, suinmi 

 convexi, sequentes planiores, ultimus augustatus, basi non com- 

 pressus; apertura piriformis; lamellae mediocres, infera alte 

 ascendens ; lunella nulla ; plicae palatales 5-6, supera 1 elougata, 

 4-5 brevissimae, subparallelae, locum lunellae obtinentis ; sub- 

 columellaris inconspicua ; perist. continuum, roseum, intus 

 callosum, imdique expaosum et reflexiusculurn, margine supero 

 repando. 



" Long. 24|, diam. infra medium 6 mill. Ap. oblique fere 

 6 mill, longa, 4jf lata." (Pfeiffer.) 



Hab. Burma: Mergui (Gould) ; Moulmain (Blanford) ; 

 Phaloung and Zwagabin (Theobald, Huny erf or d); Tenasserim and 

 Salween Valley (Beddome) ; Gethebian ku and Phabougku (Theobald). 



Is stated by Pfeiffer to be very closely allied to Cl. insiynis, 

 Gould, and philippiana, but well distinguished. 



Stoliczka observes that it is also " one of the most variable 

 species, both in colour and form. Young specimens are either 

 brown or of a beautiful rosy tinge ; older shells, after they become 

 solidified, either retain the brown or pink colour, or the lip 

 becomes yellowish-brown or perfectly white ; the 3-5 top- whorls 

 are always white. The form differs from fusiform to highly 

 turreted, as may be indicated by the following measurements : 



a. long. 23, lat. 6, long, apert. 5-2, ej. lat. 4-2 mm. 



b. 28, 6-3, 6-2, 5 



c. 32, 6-5, 6, 5 



All three specimens are from Moulmain: a is almost exactly 

 identical with Pfeiffer's original figure of the species ; b and c are 

 a white and a yellowish lipped variety from Mr. Theobald's 

 collection ; c has an almost abnormally small aperture as compared 

 with the length of the shell." 



A fairly common species. The Ginning collection contains three 

 specimens from Mergui, with pale rufous pink peristome and com- 

 posed of 10^ and 11 whorls. There are several specimens in the 

 Theobald collection : three from Moulmain, with 10J whorls, 

 measure 26 x 6'75 mm. ; three from Phabougku, with 11|- and 12 

 whorls, reach a length of 26-5 mm., with a diameter of only 

 6mm.; three from Gethebian Ku, with 10 J and 11| whorls, 

 measure 25 x 6 mm. ; while three more from Zwagabin, near 

 Moulmain, have a pink mouth and possess 11 whorls but only 

 attain a length of 22 mm., with a diameter of 5-5 mm. In the 

 Beddome collection I found a specimen from the Salween Valley, 

 pale fuscous in colour with a pink mouth, with 10 whorls,
