PUPISOMA. 35 



arcuatis, nonnunquam striis tenuioribus alternantibus, tectis, ad 

 basin convecam otaoletis ; apertura subrotundata : labio tenuis- 

 simo, levi ; rarissuno denticulo parvulo mediano instructo ; labro 

 externo tenui, paululum dilatato, edentulo, in anfractum penulti- 

 muui vix ascendente ; columella ad basin sensim expausiuscula, 

 regionem umbilicalem tegente, torta, infra subdenticulata. 

 "Diam. niaj. 1*5 ; d. min. 1-2; alt. 2 min." (Stoliczka.) 

 Hob. Burma : Moulmein (Stoliczka) ; Rangoon (flunyerford). 

 " The animal is grey with somewhat darker, very short pedicles 

 and almost obsolete tentacles. The columella of the shell is at the 

 base peculiarly expanded, flattened, somewhat twisted, producing 

 at the lower part a small denticle. The species was found on old 

 masonry of the Great Pagoda at Moulmein, and on the opposite 

 bank of the river at Martaban on similar wooden structures." 

 (Stoliczka.) 



Var. unidentata, Godwin-Austen. 



Pupa lignicola, toothed variety, Stoliczka, J. A. S. B. xl, 1871, 

 p. 172 ; Hanley & Theobald, Conch. Ind. 1876, pi. 160, fig. 6. 



Pupisoma lignicola, var. unidtntaia, Godwin-Austen, Land & Fresh w. 

 Moll. India, ii, 1910, p. 300. 



Stoliczka when describing the type states that " 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." Hanley and 

 Theobald in figuring the toothed variety do not mention its source 

 but give the habitat Moulmein, so that it is probable the shell 

 illustrated is the one recorded by Stoliczka. 



50. Pupisoma constrictum, Godwin-Austen. 



Pupa (Pupisoma) constrictus, God win- Austen, P. Z. S. 1895, p. 4-50, 

 fig. B. 



Original description : " Shell turbinate, perforate ; sculpture 

 minutely costulate above, from the swollen portion forwards the 

 surface is smoother ; colour, pale ochraceous ; spire conic ; sides 

 flat ; apex pointed ; suture impressed ; whorls 5, convex, at the 

 distance of half a turn in the spiral behind the aperture there is a 

 sharp swelling of the whorl, marking apparently the position of 

 the previous aperture, but this is not seen in any of the whorls 

 above ; aperture ovate, oblique ; peristome much thickened and 

 reflected, united by a thin callus on the body-whorl ; sinuate 

 below and on outer margin. 



" Major diam. 2-1 ; alt. axis 2-2 mm." (Godwin-Austen.) 



Hob. Andaman Islands : Port Blair, South Andaman. 



" Animal not yet seen, and it is difficult to say where this species 

 should find generic position. I sorted out from a tube full of 

 minute shells eight specimens of this very curious and interesting 

 species. Its sculpture is liKe that of Pupisoma liynicola, Stol.,
