CRYPTOSPIRA. 33 



M. OLIV^EFORMIS, Kiener. PI. 5, figs. 64-66. 



Rather narrow, flesh-color, obscurely two- or three-banded, and 

 occasionally longitudinally mottled with a darker tint. 



Length, '6 inch. 



Senegal. 



I agree with Weinkauff that M. laeta, Jousseaume (fig. 65), is 

 scarcely more than a fine, small example of this species. M. 

 Hindsiana, Petit (fig. 66), proposed instead of M. constricta, 

 Hinds, a name preoccupied by Conrad for a fossil species, is 

 probably a synonym. 



M. CARNEA, Storer. PI. 10, fig. 86. 



Orange-red, with a median narrow white band ; lip and callus 

 white. Length, '75 inch. 



West Indies, Florida, Beaufort, N. Carolina. 



This very distinct species has been misunderstood by the 

 European monographers, who have all confounded it with forms 

 of M. oblong a, Swains. 



M. ROSCIDA, R,edfield. PI. 10, fig. 88. 



Yellowish flesh-color, flecked with white, tending to become 

 longitudinally white-streaked below the suture ; lip marked by 

 two distant chestnut spots, with usually a third at its junction 



with the spire. Length, -6 inch. 



North and South Carolina. 



Is very nearly related to the next species, but the spire is 

 more developed, the shoulder more distinctly angular, and has 

 the white spots of which M. apicina is destitute. It is a. critical 

 species and may prove to be only a variety of M. apicina. 



M. APICINA, Menke. PL 10, figs. 89, 90. 



Pure white, bluish, purple, pinkish or yellowish white, or 

 orange-yellow, faintly darker banded, with two, three or four 

 chestnut spots on the margin of the outer lip sometimes obso- 

 lete. Length, -4--6 inch. 



West Indies, Florida, Bahamas. 



The pure white variety has been described by Jousseaume as 

 M. virgmea. 



M. PELLUCIDA, Pfeiffer. PI. 10, fig. 91. 



Thin, diaphanous, orange-brown, sometimes faintly banded
