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

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

Ilah. Burma : Mergui {Gould) ; Moulmain {Blanford) : 



Phaloung and Zwagahm {Theobald, Huw/erford); Tenasserim and 



Salweeu Valley {Beddome); Getliebian ku and V\vdhoi\gk\.\{TheohaU). 



Is stated by Pfeiffer to be very closely allied to CI. insignis, 



Gould, and philipinana, 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 hp 

 becomes vellowish-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. 2?,, lat. 0, long, apert. 5-2, ej. hit. 4-2 mm. 

 h. „ 28, „ 0-3, „ „ ^'2, „ „ 5 „ 



c. „ 32, ,, 0-5, „ „ 6, „ ,, 5 „ 

 All three specimens are from Moulmain: a is almost exactly 

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

 a wlnte aud a vellowisli 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. Tlie Cuming collection contains three 

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

 posed of I0.i and 11 whorls. There art; several specimens in the 

 Theobald collection: three from Moulmain, with IQi whorls, 

 measure 26x0-75 mm.; three from Phabougku, with 11 Jr and 12 

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

 Gmm.; three from Gethebian Ku, with iO| and lU whorls, 

 measure 25x6 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,
