An interesting species, well characterized by its broadly 

 eft'used aperture and pinched spire, and scaly sculpture. 

 In colour it is almost as variable as the species of the pre- 

 ceding plate. Fig. a, a bright uniform crimson-orange ; 

 fig. i, c, an orange-yellow, broadly splashed and wave- 

 clouded with black ; fig. d, e, opakc-white, very delicately 

 obliquely wave-sprinkled with minute grey dots; fig./, 

 pink, with the ridges conspicuously picked out in white, 

 encircled with three bands of open black network. 



Species 64. (Fig. a to d, Mus. Cuming.) 

 Nekita albicilla. Ner. testa subtrigono-ovatd, depres- 

 sissimd, spird obtuse pland, fere obsoktd, anfractibus 

 angustis, versus aperturam- gradathn expansis, spira- 

 liter costatis, costis confertis, plus minus obtusis, in- 

 terdum obsoletis, labro late effuso, ititus multo incras- 

 sato, vix erenulato, ared colnmellari ampld, undique 

 granulatd, mimitissime denticulatd ; colore varid. 

 The ox-palate Nekite. Shell somewhat triangularly 

 ovate, very depressed, spire obtusely flattened, almost 

 obsolete, whorls narrow, gradually expanded towards 

 the aperture, spirally ribbed, ribs close-set, more or 

 less obtuse, and sometimes obsolete, Up broadly ef- 

 fused, much thickened inwardly, scarcely erenidated, 

 columellar area large, granulated throughout, very 

 minutely toothed ; colour various.

This species is well distinguished from all others by its 

 very depressed oblong-ovate form, and narrow pinched 

 spire, the columellar area being unusually large and pro- 

 fusely granulated. In colour it is extremely variable ; 

 fig. a, d, a dark purple-black, freckled and clouded with 

 greyish-white ; fig. b, c, a brilliant crimson-orange, banded 

 with a light sprinkling of irregular grey-black dots.
