modification of the banded form is N. succincta, A. Ad. (fig. 

 119). N. Marratii, E. A. Smith (fig. 120), is a small form in which 

 the sutures are maculate ; the colored revolving lines are present 

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

 much obscured by the coloration. In N. punctata. 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. 

 compta, A. Ad. (fig. 122), is similar, whilst the inkiest specimens 

 have been called N. velata, Gould (figs. 123, 125), and N. Inctu- 

 osa, A. Ad. (fig. 126). N. lentiginosa, A. Ad. (fig. 127), has been 

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

 crenulations and red revolving lines. N. mustelina, Gould, and 

 .V. forruginea,) Marrat, both unfigured, 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. lilacina (fig. 128), and by Dunker N. coturnix (fig. 

 129). To these may be added also N. sesarma, Marrat (fig. 

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

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

 which equals N. micans, A. Ad. (fig. 132), a similarly faded 

 specimen from the Philippines. N. flava, Marrat, habitat un- 

 known, and N. polita, Marrat, from Mauritius, both unfigured, 

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

 to N. gaitdiosa. N. clandestina, A. Ad., an unfigured Japanese 

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

 nish the distinctive characters which cannot be found in the 

 description. 



N. PIC.TA, Dunker. PI. 11, figs. 133-142. 



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- 

 culate on the shoulder, incisely striate near the base. Color 

 everywhere minutely flecked with brown or ash and white, with 

 sometimes narrow brown revolving lines. Length, '6-*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
