42 HELIX-PAPUINA. 



H. (Papuina} cerope E. A. SMITH, Ann. Mag. N. H. (6th ser.), 

 vii, p. 452, May, 1891. 



This species somewhat resembles H. aurora Pfr. in form, but is a 

 trifle higher in proportion to the diameter. It also differs in being 

 a smaller form, and in having a larger umbilicus. The young of 

 this species is evidently sharply keeled at the middle, but in the 

 adult shell the keel gradually disappears toward the aperture.

H. NOVOGUINEENSIS Pfeiffcr. PL 5, figs. 89, 90, 91, 92. 



Imperforate or narrowly perforate; globose-conical, solid, the 

 spire conical, composed of 5?, slightly convex whorls; apex acute, 

 pale ; last whorl rounded at the periphery, slightly descending in 

 front. Surface shining, striatulate, covered with a thin corneous 

 epidermis, white under the epidermis, variously banded with chesnut, 

 and with an opaque-white border below the suture, the base mostly 

 chestnut. Aperture oblique, wide ; lip white, broadly expanded 

 throughout, reflexed ; columellar margin wide, dilated over the um- 

 bilicus, usually closing it, and thickened within by a deposit of callus 

 with an irregularly nodulous edge, more or less truncated below. 



Alt. 26, greater diam. 41, lesser 34 mill.

A large, globose-conic shell, variously banded with chestnut, and 

 having a white sutural border. The following seem to be merely 

 varieties ; cf. Dohrn, /. c. 



Var. TRIUMPHALIS Reeve. PI. 17, fig. 30. 



Imperforate ; broadly trifasciate with chestnut. 



Reeve's name has priority over that of Pfeiffer, and I would adopt 

 it for the species if the identity were established by an actual exami-
