Fam. Pupidse. 



This family is represented in India and Burma by Sypselostoma, Boy- 

 sia and various subgenera of Pupa, all of small si^e. Among the Pupce found 

 in Burma and the adjacent countries, inhabited by a large number of Mala- 

 yan forms, the majority are referable to Albers' subgenus Scopelophila, the 

 type of which is Pupa Kokeilii, Rossm. The shells are small, subconic or 

 subcylindrical, composed of 4 to 8 whorls, with a moderately thin, semicor- 

 neous or corneous texture, covered by a brown cuticle ; the last whorl is 

 rimate at the base, always somewhat rapidly turned to the front, generally 

 slightly ascending at the aperture, which is internally instructed with teeth on 

 the whole peristome ; commonly there is a bifid tooth on the inner lip, it is 

 larger than any of the others. Some of the species appear to differ from Pupilla 

 merely by the peculiar turn of the last whorl towards the front, thus shew- 

 ing a strong affinity to Hypselostoma. The Indian species of Scopelophila, 

 as far as I observed them, have the pedicles well developed and the tentacles 

 short. 



A second small group of Pupa, which is found in India, Burma and the 

 country southward, is characterised by a subconic or ovate shape, composed 

 of three to five whorls, of a thin corneous texture, covered with a transverse- 

 ly striated cuticle ; the last whorl is not ascending, the aperture generally 

 edentulous ; the columellar lip is externally near its attachment somewhat 

 expanded, mostly covering the umbilical region, while internally at the base 

 it is twisted and occasionally provided with a small tooth. I propose for 

 this subgeneric group the name 



Pupisoma, 



and regard as the type of it the Moulmein P. lignicola, described in 

 J. A. S. B., vol. xl, pt. ii, p. 171, pi. vii, fig. 3. The animals have very short 

 pedicles and barely a trace of tentacles. They generally live on wood.
