Family ENDODONTID.^. 



{Continued from Vol. II. p. 199.) 



Genus Pupisoma. 



PupisOMA, Stoliczlia, type P. lignicola, Stol. 



This subgenus was described by Ferd. Stoliczka in the Journ. 

 Asiat. Soc. Bengal, vol. xlii. pt. 2, 1873, p. 32. After referring 

 to the Indian subgenera Hypselostoma, Boysia, and ScolpelopliUa 

 (type Pupa Icol-eilii, llossm.), he says : — 



" A second small group of Pupa which is found in India, 

 Burmah, aud the country southward, is characterised by a sub- 

 conic or ovate shape, composed of three to five whorls, of a thin 

 corneous texture, covered with a transversely 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 generic group the name Pupisoma and 

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

 J. A. S. B. vol. kl. pt. ii. p. 171 (1871), plate vii. fig. 3. The 

 animals have very short pedicles and barely a trace of tentacles. 

 They generally live on wood." 



Stoliczka describes in the same paper of 1873, Pupisoma orcella, 

 pi. iii. fig. 2, from Penang, found on Cocos nudfera. " The 

 animal is grey with dusky pedicles, but no perceptible trace of 

 tentacles. The species differs from P. lignicola (loc. cit.) by a 

 shorter and broader form, more convex \\horls, and by a very 

 slightly expanded and thin outer lip. In fresh specimens some of 

 the ti-ansverse striae of the cuticle are rather stronger than in 

 others, but they soon wear off." 



In the subgeiuis, according to Nevill, in his amended copy of 

 ' Hand-list of the Mollusca in the Indian Museum, Calcutta,' 

 1878, p. 192, are the following species : — 



No. 50. P. LIGNICOLA, Stoliczka. 



" 30. Kangan caves near Moulmain (type), coll. Dr. F. Stoliczka." 



In same lot from " Moulmain. Unique specimen, a toothed 

 variety — var. unidentata " *. Referred to by Stoliczka in his 

 description, p. 172, as follows : — " Out of a great number of 

 specimens only one was met with which has a small tooth about 

 the middle of the inner or parietal lip ; its presence, therefore, 

 must be regarded as an exceptional character." 



Mr. Ilanley has figured a toothed variety, but he does not say 

 from whom he got the specimen. 



* Coneh. Indica, Plate clx. fig. 6. The colouring is very strong, not at all 

 like any specimen I have seen, very like that of a Glessula.
