Vivipara magnifica. 



A continuous elevated, heavy, revolving line sometimes takes 



the place of nodules. The interior of the 



aperture varies from pure white to a rich 



dark purple ; it is sometimes of a salmon 



color ; the bands are also very variable in 



number and width. There are also some- 

 times dark green bands on the exterior of 



the shell. I have counted as many as four 



on the body whirl alone. It is variable in 



size. One specimen which I measured was 



50 mill. long. It inhabits Alabama and 



Georgia. 



Fig. 1 is a fac-simile of the outline of 



Conrad's figure. I have added below a figure of Mr. Lea's species, 



which is, I believe, identical, fig. 21 being a fac-simile of Mr. 



Lea's figure, and fig. 22 being take nfrom a specimen determined 

 by Mr. Lea. No. 8928 of the collection was labelled 

 Pal. angulata by Mr. Lea. Haldeman agrees with 

 me in considering this last 



Fiwfiammasr- identical with V. magnifica. I S- 21.

walter for the other specimen figured. 



Paludina bimonilifera, Lea. — Shell obtusely

 furnished with two rows of nodules ; the nodules 

 of the lower row of the upper whirls hidden by 

 the suture, those of the upper row larger, and

 regular ; outer lip sub-biangular ; base sub- 

 angular.
