 Pfr., Pro. Zool. Soc, 1854, p. 149. 



Rveve, Cone. Icon. sp. 1353. 



Shell umbilicated, globosely- turbinated, slightly solid, very finely obli- 

 quely striated, and, under the lens, covered with extremely faint 

 short minute lines, giving the appearance of lengthened granules, 

 reddish-yellow, spirally banded and lineated with deep chestnut, 

 darker about the mouth ; spire broadly-conoid, obtuse ; whorls 6, 

 slightly convex, last convex, above strongly deflected in front ; base 

 marked as above, umbilicus deep, nearly covered ; aperture diagonal, 

 ovately-lunate, white within, then purplish ; peristome simple, white 

 or purplish, straight, margins somewhat converging, right expanded, 

 basal reflected, columellar margin above broadly dilated and re- 

 flected at the umbilicus, which it nearly conceals. 



Diameter, greatest 1*50 ; hast 1*25 ; height - 85 of an inch. 



Habitat. Port Denison, Queensland. Masters. 



This, which is a beautiful representative of the larger, more solid, 

 black lipped, and ex-umbilicated H. Fraseri, is generally banded in 

 a precisely similar manner to that species. It has, however, equally 

 close affinities with PL. Lessoni, evident only after examination of a 

 large series of specimens.

 Reeve, Cone. Icon. sp. 1348. 



Shell umbilicated, turbinately-globosj, striated, under the lens 

 minutely granulated, somewhat glossy, translucent, above reddish- 

 yellow, base below periphery of body whorl deep chestnut ; spire 

 depressly-conoid ; whorls 6, slowly increasing, slightly convex, last 

 deflected in front ; aperture roundly-lunate, white within, thickened 

 with a callus, expanded, and on anterior and columellar lips reflected, 

 above concealing ^ of the umbilicus. 



Diameter, greatest 1"65 ; least P40 ; height POO of an inch. 



Habitat. Islands of N.E. coast of Australia and Torres Strait, 

 from Lizard Island to Stephen's Island. 



This species, unquestionably a modified H. bipartita, is so vari- 

 able that a dozen well marked varieties might easily be selected 

 from among the hundreds of specimens now before me. I have 

 taken the preceding description from a Lizard Island specimen. On 

 the peak of that island, the late Mr. MacGillivray found very large 

 and thin specimens under stones, and on the lower grounds, in the 

 scrubs, about the roots of trees, and among dead leaves, a smaller, 

 stouter, and brightly coloured but variable form was abundant; while
