GT7DE : ON NEW SPECIES OF CHLORITIS. 229 



4. C. quercina, var. Homlroni, from Florida Island. An extra- 

 ordinary pyramidal form, the last three whorls planate above, flattened 

 below, obtusely keeled, the keel exserted in all but the last f whorl. 

 Suture superficial. Diam. maj. 375, min. 32 mm. ; alt. 24 mm. 



Both the type and the variety are represented by bipartite specimens, 

 ■with the upper side ochreous-brown, the lower straw-yellow. 



5. C. Challengeri, Byron Bay, New South Wales. A new habitat. 

 One other specimen is labelled Clarence and Richmond Rivers. 



6. C. Novocambrica, an elevated form, labelled "Scrubs 8 miles from 

 the North Pine River, Queensland." A new habitat, the type being 

 described from New South Wales. Diam. maj. 15, min, 12'5mm.; 

 alt. 11 '5 mm. A second specimen measures : diam. maj. 12, 

 min. 10 mm.; alt. 8'5 mm. 



In ray former paper, on p. 116, the references to C. Marimherti and 

 C. Balansai, var. cincta, have by a printer's error unfortunately been 

 transposed in the footnotes Nos. 2 aud 3. 



DESCRIPTIONS OF NEW SPECIES. 

 Chloritis conomphala, n.sp. PI. XXI, Figs. 1, a^d. 



Shell widely umbilicated, depressed globose, distinctly and regularly 

 striated, pale ochreous, the last whorl pale fulvous, covered with 

 sparse hair-scars arranged in quincunx. Spire low, subplanate, apex 

 immersed, suture deep. Whorls 4^, convex, increasing regularly, the 

 last somewhat suddenly, slowly descending and shortly deflexed in 

 front, a little diluted at the mouth, obtusely angulated round the 

 funnel-shaped umbilicus, which shows the entire penultimate whorl 

 within. Aperture subcircular, little oblique, the margins convergent, 

 united by a thin callus, peristome rosy-fulvous, thickened, shortly 

 expanded and reflexed ; upper margin arcuate, outer and basal 

 rounded, columellar slightly dilated above, impinging upon the 

 umbilicus. Major diam. 21-5, min. 17-5 mm. ; alt. 14 mm. 



Hah. — Rubiana, Solomon Islands. 



Type in Dr. Cox's collection. Allied to C. discordialis, but smaller 

 and with the hair-scars much more sparsely placed ; the peristome is less 

 expanded, the last whorl less dilated, and the aperture consequently 

 smaller ; the last whorl also descends less, and the umbilicus is not so 

 widely excavated. A second specimen measures : major diam. 20, 

 min. 16'5mm. ; alt. 12-5 mm. 



Chloeitis munda, n.sp. PL XXI, Figs. 2, Or-d. 

 Shell moderately umbilicated, discoid, dull, dark cinnamon brown, 

 finely irregularly striated, the nepionic \\ whorls minutely granulated; 

 covered with distant small warty tubercles (probably bearing hairs 

 when fresh) arranged in quincunx. Spire planate, apex almost 

 immersed, suture deep. Whorls 4^, convex, increasing regularly, the 

 last rather suddenly, a little dilated towards the mouth, very slightly 

 descending in front, slightly compressed below, and obtusely angulated 

 round the slightly excavated umbilicus. Aperture ovate - lunate, 

 oblique, margins convergent ; peristome thin, fulvous, upper and outer
