HELIX-PAPUINA. 55 



closely allied to H. naso, the coloration of some specimens of 

 the two species being identical. 



My description and figures are from a specimen received from 

 Mr. Brazier. 



H. MACGILLIVRAYI Forbes. PI. 3, figs. 38, 39. 



Imperforate, trochiform, the spire straightly conic, periphery car- 

 inated, base rather flattened ; of an opaque fawn or fleshy-brown 

 tint, occellated with small translucent dark dots, irregularly bestrewn ; 

 apex purple-black ; lip white, sinuous. 



Surface conspicuously decussated with oblique and spiral striae, 

 the latter stronger impressed. Spire straightly conical, whorls 5J, 

 slightly convex, the last angulated at the periphery, rather abruptly 

 descending in front. Aperture very oblique, light brown and dotted 

 within ; upper margin of peristome bent downward, bisinuate ; basal 

 margin narrowly reflexed, adnate toward the center ; a dark brown 

 spot at the root of the columella. The lip is bordered outside with 

 creamy, behind which there is a blackish stripe. 



Alt. 20, greater diam. 20*, lesser 18 mill. 



Fitzroy and Frankland Is. off N. E. Australia ; and on the main- 

 land 28 miles inland from Cardwell, Rockingham Bay (alt. 3500 ft.)

A beautiful species, allied to H. naso and some other Papuan spe- 

 cies in form of the lip, but totally different in sculpture and color- 

 ing. 



H. BIDWILLI Pfeiffer. PI. 3, figs. 52, 53. 



Imperforate, elevated-trochiform, the spire straightly conic, periph- 

 ery keeled, base flat; lusterless whitish, irregularly spotted with 

 chestnut above, the base chestnut, spotted with white; peristome 

 dark chestnut. 



The surface is decussated by very fine oblique and spiral stride, and 

 besides is very obsoletely obliquely wrinkled. Whorls 51, nearly 

 flat, the last angular, a little descending in front, flat below, con- 

 tracted at the aperture. Aperture very oblique, somewhat angled 

 at the position of the carina, pinkish-brown within ; peristome edged
