SYKES : DESCRIPTIONS OF NEW LAND SHELLS. C5 



Hah. — Halnialiera ; a more polished and shining form from Obi. 

 NoteArortliy for its colour pattern, consisting of a dark brown peripheral 

 band, and the other white zones, which are usually' interrupted. 



Papuina eallosa, n.sp. 



Shell trochiform, yellow-brown, either unicolorous or with a dark chestnut 

 band at the periphery and below the suture on the last whorl, this colouring 

 also being exhibited by the somewhat mamillate protoconch ; sculpture 

 well-marked lines of growth and minute granulations, the protoconch 

 having faint radiating striae. Whorls 5|, flattened, the last whorl descend- 

 ing a little, being flattened on the base, acutely keeled at the periphery, 

 and somewhat compressed behind the mouth. Mouth sub-quadrate, the 

 lip reflected and expanded, especially on the lower and cohunellar margins, 

 where it is thickened also internally, and the columellar margin is furnished 

 (generally) with a broad flattened callosity ; the lower margin is slightly 

 impressed from below, producing the effect of an obscure denticle in the 

 middle. The lip is well expanded over the umbilical region, and is purplish- 

 brown in colour, becoming darker at the edges. 



Alt. 16.5 ; diam. max. 27 millim. 



Hah. — Halmahera. 



Papuina wallaeeana, n.sp. (P. aurora var. b.) 



Shell large, thin, depressed-conoid, moderately umbilicate, the umbilicus 

 being partly concealed by the reflected columellar margin of the lip ; 

 slightly compressed on the base ; sculpture consisting only of lines of 

 growth, which give a roughened appearance to the shell ; protoconch 

 small. Colour yellow-brown, with (in the type) six narrow blackish- 

 chestnut bands, one at the periphery, two above, and three below ; other 

 specimens lack the bands of colour. Whorls b^, slightly convex, with 

 the suture well marked, last whorl a little descending. Mouth sub-ovate, 

 with a hlac peristome, which is reflexed, expanded, and slightly thickened- 

 especially below ; columellar margin well reflected over the umbilicus. 



Alt. 21 ; diam. max. 36 millim. 



Hah. — Waigiou. 



Recalling in colour of shell and lip the unlocalised P. pennantiana, 

 but lacks the acute carination of that species ; in shape it resembles a 

 depressed P. multizona ! much larger than P. aurora. 



Papuina pypgus, n.sp. 

 Shell perforate, the perforation being nearly covered by the reflexed 

 columellar lip, solid, conical ; sculpture, well-marked lines of growth ; 

 colour olivaceous ; spire moderately elongated ; protoconch large and 

 smooth. Whorls 7, plano-convex, a trifle concave above the sutures, the 

 last whorl not descending, acutely keeled, with the base flattened. Aper-
