248 LAND AND FRESH-WATER SHELLS OF K. A. [PART IV. 



yellow, inclining to brown, with a darker brown band on each whorl, 



increasing to two ou the body-whorl ; whorls 7-8, rather convex ; 



suture deeply impressed ; aperture ovate, within dusky-white, with 



Fi"- 483a ^^"^ outer bauds seen faintly through its substance ; colu- 



tmella beautifully rounded ; outer lip produced, a small 

 sinus at base. 

 Habitat. — Wisconsin. 

 Observations. — A very beautiful and lively species. Bears 

 some resemblance to M. pulchella (nobis), but is elongate, 

 more delicately colored, and of a less solid texture; the bands are 

 often obsolete, and never so distinctly expressed as in jiulchella ; its 

 spire is also more acute, and the whorls more rounded. Compared 

 with 31. hrevispira (nobis), which in form it resembles, it is more 

 attenuate, has a greater number of whorls, and its bands also distin- 

 guish it. Its delicate yellow color also is not a common character in 

 the genus, and forms a prominent mark for determination. — Anthony.
