64 Land Sells of the Tenasserim Provinces. [Jan. 



The genus Cyclostoma has three representatives in our Tenasserim 

 jungles. 



C. tuba, Sowerby, is more common, perhaps, than any other spe- 

 cies. 



C. pernobilis,* Gould, is also very abundant. It is the largest land 

 shell in the country, and the largest species of its genus. 



The Karens call it K16-mu-pgha, the primary shell, i. e. the one 

 from which others are derived. The Burmans call it Kh6-ru-quet, 

 the Quet shell ; as they say it calls out Quel, quet ! Nearly all the 

 different species of Helix above are called by the Burmans varieties of 

 the Quet shell. " Diameter 2 inches ; height 1 inch. This superb 

 species is a little larger than any one hitherto described. The C. 

 involmdus, Sowerby, is a miniature of it." 



C. sectilabrum, Gould, has an elevated spire with eight whorls. 

 " Length 1 inch ; breadth ^ of an inch. Closely resembles C. altum, 

 Sowerby, but has the fissure across the peritreme on the opposite 

 side. C. croceum, Sowerby, may be only a faded specimen of this 

 shell." 



We have three species of Bulimns. One, a small red species, Dr. 

 Gould thought to be new, but hesitated, and he has not therefore de- 

 scribed it. 



B. atricaJlosuSyf Gould, is a large and elegant sulphur-coloured 

 species with seven whorls. It is a great favorite with Karen females 

 and is often seen strung, with the other species of the genus, on their 

 necklaces. They call it Klo-bau, K16-bang, the yellow shell. The 

 Burmans call it Bying-khza, heroes dung. "Length x \ inches; 

 breadth 1 inch. It is of the same type as some of the shells from the 

 Philippine Islands, as B. vittatus, dryas, and maculiferus." 



B. moniliferus, Gould, is a variagated shell with seven whorls, for 

 the most part sinistral, but I occasionally meet with dextral shells. 

 " Length y ; breadth ^. Differs from B. contrarius and B. Icevus, 

 Mull , by its angular aperture, and the colour of its lip and throat." 



I have met with one species of Clausilia, the largest species of the 

 genus known. Dr. Gould named it C. insignis, but subsequently 

 wrote C. insignis is C. cochinchinensis, Philip})], published about the 

 time I received your specimens."
