SPECIES OF I'APUINA, PLANISPIRA, STROPHOCHKILUS AND DRYMAEUS. 23 



Papuina suprapieta, n. sp 



I'l. vi, fig. 7. 



Shell niodeiately solid, imperforate, broadh trochcjid. whitish above, the 

 upper surface of last whorl greenish-yellow, irregularly covered with a mottled 

 dark-brown somewhat deciduous periostracum, the under-side being of a 

 gieenish-vellow colour sharply separated at the periphery by a narrow white 

 band which is continued above at the suture of the last whorl, rather sharply 

 carinaced at peripherv of 1 odv whorl ; whorls 5},, moderately convex, regular- 

 ly increasing, smooth excei)t for the somewhat C()n-[)icuous lines of growth, 

 on the under-side of the last whorl there are traces of impressed spiral lines : 

 aperture very oblique, white within ; peristome rather broadly expanded and 

 slightly reflected, leaden whitish colour, descending somewhat at its termina- 

 tion. 



Maj. diam. 26, alt. iS millim. 



Hah. — New Mecklenburg (New Ireland). 



Comes next to humilis, Fult., but is of a flatter form, further, the more 

 oblique aperture, carinate last whorl, and different coloration above separate 

 it from that species. 



Planispira (Cpistigibba) teetorium, n sp. 



PI. vi, fig. 3. 



Shell discoidal, moderately depressed, umbilicus about 2 millim. wide, sub- 

 transparent white with a narrow, pale yellowish brown band encircling the 

 last whorl just above the periphery and continued at the suture of the 

 penultimate whorl, spire convex, almost smooth, the oblique lines of growth 

 not very conspicuous ; whoxls 5, slightly convex, last descending to the 

 periphery ; aperture very oblique, outer band shewing through ; peristome 

 rather thin, constricted behind the last whorl, slightly above, but deeply 

 behind the columellar portion, right margin slightly expanded, rather broadly 

 so at columellar portion, which has a slight tubercular swelling about the 

 middle. 



Maj. diam. 20, alt. 12 millim. 



Hab.—New Guinea fcoll. Dr J. C. Cox). 



By its coloration and non-planate spire, this sjiecies differs from any 

 other of the group known to me. 



Strophoeheilus (Borus) rugosus, nn. 



= sanfarmzi, Pfr. : Monog. Hel,, \'ol. ii, p, 23., Novit. Conch., vol. iii, 

 p. 416, pi. 95, figs. I, 2. 



= santacruzi, Pilsbry : Tryon's Manual, vol. x, p. i 7, pi. 4, fig. 3. 



Strophoeheilus santarruzi, Orbigny, of which I have seen type in the 

 Orbigny collection, and also a co-type from the Morelet collection (ex Paris 

 Museum), is quite distinct from the specimens identified as that species by 

 Pfeiffer and Pilsbry.
