The Andes-inhabiting Heli.x. Slicll umbilicatcd, de- 

 pressed, thin, granulated throughout, opake, horny- 

 white, filleted with numerous red, interrupted, den- 

 ticulated or spot-tessellated bands, the interstices 

 between them being red-flamed ; spire flat ; whorls 

 four, convex, the last dilated, rounded ; apertm-e 

 rotundately lunar ; lip thin, margins joined by a thin 

 callosity, upper margin shortly expanded, basal a 

 little reflected, columellar margin dOatcd and re- 

 flected, half-covering a narrow umbilicus.

Hab. Eastern Cordilleras, Columbia. 



The bands are very irregular, and in one or two in- 

 stances are little more than lines.

 mate subcalloso, re/lexo. 



The kosary Helix. Shell umbilicatcd, depressed, thin, 

 very finely granulated at the upper part, then ob- 

 liquely wrinldcd, diaphanous, pale fulvous, orna- 

 mented with three necklace-like bands, and with red 

 flames coming out of the suture ; spii'c flat ; whorls 

 four to five, convex, the last rather depressed, en- 

 graved with a few spiral lines, slightly compressed 

 around the funnel-shaped umbilicus ; umliilicus rather 

 oblique, triangularly lunar ; lip rather callous, re- 

 flected.

A subtransparent homy shell, delicately pencilled with 

 red-dot bands and flames.

 The chain-beabixg Helix. Shell umbilicatcd, de- 

 pressed, somewhat inflated, distinctly granulated 

 throughout, thin, rather transparent, homy-white, 

 ornamented with red-dotted bands, with irrcgidar 

 blotches next the suture ; whorls five to six, convex ; 

 umbilicus rather large ; aperture lunar ; lip thin, 

 somewhat reflected.

 Uab. Andes of New Granada. 



The painting of this species is very similar to that of 

 the last, except that instead of being in regular flames 

 next the suture, it is in irregidar blotches. There are no 

 oblique wrinkles on the surface, which is distinctly gra- 

 nulated throughout.
