PUPISOMA CIRCUMLITUM, n. Sp. 

 (Plate xi., figs. 1, 2, 3.) 



Shell globose conical, perforate, thin, translucent. Colour an 

 uniform pale tawny olive. Whorls three and a-half, well rounded ; 

 suture impressed. Sculpture, — everywhere the whorls are crossed 

 by fine, close, raised hair lines ; at irregular intervals these tend 

 to rise into lamellae, which latter can scarcely be detected in pro- 

 file on the periphery ; the embryonic shell is similarly sculptured, 

 no trace of spiral sculpture can be seen ; a break at the completion 

 of the second whorl suggests that here ends the nepionic shell. 

 Umbilicus minute, funnel shaped, showing only the preceding 

 whorl. Aperture very oblique, ovate lunate, lip simple, columellar 

 margin broadly reflexed over the umbilicus ; callus thin, trans- 

 parent. Height, 1 '9 ; breadth, 2 mm.

 the European Balea perversa, which adopts the same habit in 

 similar situations. Occasional abrasions seem to show that the 

 colour resides in a very thin epidermis. 



I have not the advantage of being autoptically acquainted with 

 any of the known Pupisoma, but the novelty corresponds so closely
