modification of tin? handed form is .V. xnri'int'tci, A. Ad. (tic;. 

 110). N. MorraHi. K. A. Smith (fig. 120), is n small form in which 

 the sutures are maculate; the colored. revolving lines -a re present 

 in the specimens before me, but in the darker colored ones are 

 much obscured by the* coloration. In N. punctaln. A. Ad. (fig. 

 121), the sutural painting is retained, but the shell is so clouded 

 with dark chocolate-color as to obscure the other markings. N. 

 f-ontpta, A. Ad. (fig-. 122), is similar, whilst the inkiest specimens 

 have been called 2V. rrh.ta. Gould (figs. 123, 125), and N. li/<-fn- 

 O.SY/, A. Ad. (fig. 126). X. lenticiinosa, A. Ad. (fig. 127), has been 

 proposed for shells allied to punctata, dark in color, with sutural 

 crenulation> and red revolving lines. N. ii<uxh>lina, Gould, and 

 .V. ferruginea, Mai-rat. both mifigured, are also probably syn- 

 onyms. A light colored or nearly white variety, with the 

 revolving brown lines and brown maculations, has been called by 

 Gould N. Uhiriini (fig. 128). and by D nnker X. i.-ofurnu- (tig. 

 129). To these may be added also X. wnai-nt-d, Marrat (tig. 

 130). from Whydah. Coast of Guinea, W. Africa; and X. pal- 

 litlttiu. A. Ad. (fig. 131), a faded specimen from Malacca, and 

 which equals X. -nit'-ann. A. Ad. (tig. 132), a similarly faded 

 specimen from the Philippines. A', /lui-a,. Marrat, habitat un- 

 known. and X. polita. Marrat. from Mauritius, both uniigured, 

 are, judging from the descriptions, at least very closely related 

 to A'. 'j(indivi$u. X. flandi'itlina, A. Ad., an uniigured Japanese 

 species, may also be placed here until a figure may perhaps fur- 

 nish the distinctive characters which cannot be found in the 

 description.

Shell broadly ovate, very smooth and polished ; spire short. 

 conic, first finely, then distantly, undulately plicate; ; body whorl 

 narrowly round-shouldered above, sometimes obsoletely tuber--

 everywhere minutely flecked with brown or ash and white, with 

 sometimes narrow brown revolving lines. Length. -(>-'8 inch.

It is with considerable hesitation that I allow this to stand as 

 a distinct species from the preceding, with which it has much in
