Apparently differs from 1). obltquus in having the aperture longer 

 and the apical sculpture ditlerent. The number of bands varies fmm 

 4 to 0, but th- uppermost, a line al the suture, is generally absent. 

 It varies considerably in degree of elongation, some shells before me 

 having the body-whorl shorter and more convex than any of tho^e 

 illu>trated on my plate. Menke's II. <>///ji/i<i/o<li'S was founded on 

 short examples, with the aperture relatively larger than in the typ- -, 

 measuring 15 mill, long with a shell length of 31 mill. 



The coloring of Spix's type is that shown in lig. 1, streaked, with 

 a ba>al band. Moricand based his ru.i I'/rana upon handed shells, and 

 gave names to the several color-1'orins. But slight sv.-t"inatic im- 

 pnrtance attache.- to these band-varieties, which are as follows: 

 }'i/r<itu-f,n/i>ifu, -Ireaked like tig. 1, but bamlless; ntn'i;>/i>r, citron 

 yellow throiiglioul (tig. }) ; tri.inm. three dark bands on a light 

 u'roiind (lig. 1'); ill <>nn, t\vo liands (tig. 5); iift/rrsiTHS, upper two 

 bamU united (tig.. 1 !); /i rj>nr<is<-, -//\, a single subperipheral vinous 

 band.
