Testa parva, depressa, orbicularis, acute carinata, aperte umbilicata, 

 fusco-cornea ; spira convexa, parum elata, ad apicem obtusa ; an- 

 fractus 4 1, apicales duo convexi, vitrei, politi, Iseves, cseteri convexi-

Hah. — Kapaur, south-west coast of New Guinea (Doherty). 



The excessively oblique costae are very strong upon the periphery, 

 and give the keel an exceedingly pretty crenulated appearance. 



2. Planispira dflcissima, n.sp. PI. II, Fig. 22. 



Testa depresse subglobosa, anguste umbilicata, saturate purpureo- 

 nigra, zonis angustis tribus albis, et zona lata rufa supra cincta, 

 hand nitida ; spira depressa, ad apicem obtusissima ; anfractus 4, 

 convexi, sutura profunda sejuncti, superiores duo puncturati, caeteri 

 lineis incrementi tenuibus striati, ultimus antice paulo descendens ; 

 apertura obliqua, irregulariter lunata, intus nigrescens, albo fasciata; 

 peristoma album, leviter incrassatum, anguste expansum, subreflexum,

 min. 14-5 mm. ; alt. 12 mm. 



Hob. — Kina Balu, North Borneo (A. Everett). 



Well characterized by its style of coloration. Of the three white 

 narrow bands, one is peripheral, another near but not quite at the 

 suture, and the third intermediate. Between the two latter the 

 surface is of a rich red colour, and not like the rest of the shell, 

 a deep purplish-black.

 Naturk. Berlin, vol. i (1898), p. 28, pi. ii, figs. 15, 16.i 



^ My description and figure being already in press -when Dr. von Martens' paper 

 reached me, I judged it best to let them stand and merely to substitute his name for 

 the one I had proposed.
