.//. Qilberti and II Jcrvisensis ; varieties of it are frequently of a dark 

 chestnut colour, Plate I. Fig. 9, others of a pale straw colour, 

 Plate X. Fig. 7, where the presence of the band at the suture 

 and round the umbilicus are altogether wanting. A third variety 

 also occurs, Plate I. Fig. 4, where the shell is surrounded with 

 a broad pale-yellow band.

 paler towards the apex ; spire widely conoid, obtuse at the apex ; 

 whorls 0, gradually increasing, moderately convex, last descending 

 in front ; base shining, obsoletely granulated, but the radiate striae 

 very distinct at the umbilicus ; aperture Innately-rounded, within 

 livid, pearly ; peristome straight, obtuse, expanded, white or bluish,

 triangularly expanded and almost entirely covering the umbilicus, 

 leaving merely a narrow fissure.

The locality of the specimen in the Cumingian collection, described by 

 Pfeili'er and figured by Peeve, who copies the original description, 

 was doubtful, but in Vol. IV., p. 167, of lion. ITel. Via., it is stated 

 thet there is a variety, of a dirty yellow colour, from Western Aus- 

 tralia. My description is taken from specimens from Kiama and the 

 Clarence Piver Heads, representing the type. But this species varies 

 considerably, inosculating even with II. Grayi, A remarkable 

 variety of great size from Kiama, chestnut below and yellowish above, 

 with white lip., is figured in PI. VIII., Fig. 10. A pink lip is usual 

 among those from Merimbula, Kiama, and especially the Nulla 

 Mountain, and the size is smaller than in the type. At Ash Island 

 a rather small stout variety is found, chestnut, with pinkish lip ; 

 this inosculates with a variety of LT. Grayi. The last variety 

 to be mentioned, figured PL X., Fig. 5, very dark, granulated 

 and ribbed as usual, with pink lip and livid mouth, does 

 not present any tangible specific difference from the preceding. It 

 is from Ulladulla, collected by Mr. Masters. Although of small 

 dimensions, 0-90. 0"75. (K50 of an inch, the lip is fully formed, the 

 umbilicus perfectly closed, and a thin callous deposit extends between 

 the margin.
