olilique. The latter is also more acutrly cariiiatfd, and the 

 last whorl descends even less than in (Jrosse's species. 



I have also received subtussil specimens Irom the sainc^ 

 locality. 



A. uovacula, ]\Iarts., is a fliitter shell with a more oblique 

 aperture, sharply angular at the umbilicus, and its last whjrl 

 dues not descend. 



Tropidophora carnicolor, sj). n. 



Shell globose-conic, moderately thick, uinbilicated to width 

 of about 3 millim.; first three whorls yellowish, last two and 

 a halt" of a deep Hesh-colour, underpart of last whorl of a 

 lighter shade, encircled on last whorl immediately below the 

 ])eriphery by a bluish-black spiral band about 1 millim. wide; 

 whorls 5^, very convex, Hrst two smooth, others sculptured 

 with distinct, regularly spaced, spiral lira3, about 18 on upper 

 part of body-whorl; just above the colour-band and for a 

 little disvance below, tlie S[)iral structure is lacking, leaving a 

 ■ smooth zone about 3 millim. wide; aperture almost circular, 

 orange-yellow within, outer band showing through ; peristome 

 thin, almost continuous, outer margin narrowly, cohunellar 

 margin broadly expanded but not reHected, partly obscuring 

 the umbilicus ; 0[)erculum normal, slightly concave, consist- 

 ing ot about tour regularly increasing whoils. 



Alt. 21, maj. diani. 22 millim, 



hah. Fort Uauphin, Madagascar. 



Allied to T. asperttm, Pot. et Mich., but easily distinguished 

 from it by the smooth zone on last whorl. In 7\ caniicolor 

 the spiral lirse are not so coarse, not so distinctly ducussatetl 

 by the oblique striie, and the colour-band of body-w.iorl is 

 situated a bitle lower than in the former species. 



Tropidophora crenidatuin^ sp. n. 



Shell oblong-jjyramidal, narrowly but distinctly nrnbili- 

 cated, moderately thick, pale yellow, with a darl<-coloured 

 band just below periphery of last and continued at suture of 

 penultimate whorl, sometimes with several narrow spiral 

 bands above the periphery ; suture rather deep and delicately 

 crenulated ; whorls 5, very convex, first two smooth, lower 

 whorls with inconspicuous oblique strige crossed by numerous 

 .spiral line, the last half-whorl iiaving a somewhat malleatcd 

 aj)pearance; aperture circular, slightly oblique, yellow witiiin, 

 outer band showing through ; peristome thin, very slightl}^ 

 thickeried and expanded, continued over parietal wall by a 

 somewhat raised callus ; operculum slightly concave, the 

 nucleus (1^ whorlsj darker coloured and sunken.
