MITRELLA. 



chestnut band ; whorls flatly convex, smooth ; aperture small, lip 

 simple. Length, 7-9 mill. 



Iba, Province of Zambales, Luzon, Philippines (Cuming). 

 I have before me two specimens said to come from Australia 

 which perfectly agree with the above shell except that the outer 

 lip is toothed within ; if they are of this species, they connect 

 it with C. impolite. 



C. TNTEXTA, Gaskoin. PL 47, figs. 60-02. 



Shell acicular, smooth, with revolving stria? at the base ; white, 

 longitudinally strigated and spotted with dark chestnut or choco- 

 late ; outer lip smooth, or slightly plicate within. 



Length, 18 mill. 



Darnley fsl., Torres Sts., N. Australia (Brazier). 

 The synonymy includes C. fusillus, Reeve (fig. 61) and C.

C. ACHATINA, Sowb. PI. 47, figs. 63, 64. 



Shell smooth ; yellowish white, marbled and longitudinally

 with basal revolving striae ; aperture brownish or violaceous, 

 outer lip thickened and dentate within. Length, '8 inch. 



Swan River, Australia.

 (probably enlarged) figure in Reeve (fig. 64). 



C. LINCOLNENSTS, Reeve. PI. 48, fig, 65. 



Shell smooth, shining, striate at the base; spire long, sharp 

 pointed; whorls flattened; yellowish white, covered by a network 

 of chestnut, sometimes sparsely, and frequentty so close as to 

 cause the surface to appear a uniform chestnut-color; aperture 

 chestnut or violaceous within, the outer lip interiorly dentate. 



Length, 12 mill. 



Australia, Tasmania. 



This is a common species ; and may be a small variety of C.

C. MENKEANA, Reeve. PL 48, fig. 66. 



Narrowly acuminated, smooth, fulvous, encircled sometimes
