virgineus, an error detected by Bruguiere. Drouet gives it among 

 his Guiana shells, from a locality near Cayenne. If it exists there, 

 it was evidently introduced by French commerce. 



L. POEYANUS (Pfeiffer). PL 55, figs. 55, 56, 57. 



Shell dextral or sinistral, oblong-turreted, somewhat fusiform, 

 solid, whitish, becoming deep pink above, and more or less yellow 

 on the latter part of the last whorl, with three narrow brownish 

 black bands in the typical positions, sometimes with a light chestnut 

 band bordering the suture below and a chestnut patch around the 

 columella. Smooth and glossy, whorls 8, moderately convex. 

 Aperture oblique, pink within ; outer lip acute and simple ; col- 

 umella and parietal wall rose-colored, the former destroyed by crabs 

 in the specimens known, but said by Poey to be truncated. 



Alt. 43-48, diam. 18-20 mill.

Similar to L. virgineus, and unlike all other Cuban Liguus, in the 

 three blackish bands in the typical positions for bands in this sub- 

 family. The pink-calloused interior, narrow 7 form and smooth sur- 

 face, as well as the truncated columella, are also like L. virgineus, 

 from which species it differs chiefly in distribution. The tapering 

 base of the last whorl, however, is not quite like virgineus. 



The shells collected by Gundlach and sent Pfeiffer had all been 

 inhabited by Paguri, the columella being worn away. Those before 

 me are also in this condition. According to Gundlach the majority 

 of the specimens are sinistral. None have been observed with 

 green, purple or red bands, though the spaces between the peripheral 

 and upper, and below the lower dark band, become straw-yellow 7 on 

 the latter part of the last whorl in one of the shells before me. 



I think Swainson's A. vittata corresponds much better with this 

 species than with L. virgineus, but as there is some doubt, I do not 

 give it precedence.
