Staffoedia daflaensis, G.-A. Shengorh Peak, 7000 feet. 

 (Plate CXIII. figs. 1-1 i.) 



Shell depressedly tumidly conoid, umbilicated, solid, rather flat on 

 base. Sculpture very regular, longitudinal, sharply defined, broad- 

 ridged ribbing. Colour rich olivaceous with ochre tint. Spire 

 low, sides convex. Suture shallow, adpressed. Whorls 6, rapidly 

 increasing, the last rounded; aperture broadly ovate, oblique, 

 milky white within ; peristome acute, sinuous above and slightly 

 so below, much reflected at umbilical margin. Columellar margin 

 very oblique and descending. 



Major diam. Minor diara. Alt. axis. Alt. b.-w. 



Largest size : 23-5 20-0 9-4 7-8 mm. 



Smaller size: 18*8 16-2 8-0 5-8 „ 



It was an abundant species in the Dafla Hills, varying much in 

 colour and size, often being of a pale ochraceous-grey tint. On 

 Toruputu Peak it occurred also with the same characteristic sculp- 

 ture, but thinner in structure. 



One very globose example was found on this same peak. 



Staffoedia daflaensis, var. (Plate CXIII. fig. 2.) 



Shell: sculpture coarse longitudinal ribbing, rather irregular. 

 Colour ochraceous olive-green. 



Size : maj.diam. 16-4, min. 14-8 ; alt. axis 8-0, alt. b.-w. 6-5 mm. 



Macrochlamys shengorensis, G.-A., described and figured in Vol. I. 

 p. 102, PI. XXII. fig. 5, is the young of Staffordia daflaensis, G.-A. 



A globose shell with oblique columellar margin, which may be an 

 ally of S. daflaensis, was found on Toruputu Peak. The sculpture 

 differs much, being smooth with indistinct striation ; and as the 

 animal might prove quite different I have distinguished it aa 

 toruputuensis. 



Staffoedia? TOEUPUTtrENsis. (Plate CXIII. fig. 3.) 



Shell not fully grown ; sculpture very smooth, with a thick shining 

 epidermis with indistinct striation ; colour light ochraceous olive- 

 green. 



Size : maj. diam. 16"5, min. 14*0 ; alt. axis 7'25. 



The following species, of which I have only one specimen, diff'ers 

 so much that I have thought fit to distinguish it by name — the 

 sculpture alone is so very difi'erent from those described above. A 

 larger series, of full growth, is required to settle these differences. 



Staffoedia staffoedi, n. sp. Toruputu Peak, Dafla Hills, at 

 7000 feet. (Plate CXIII. fig. 4.)
