126 LAXJBIA, AZORES ISLANDS. 



53. Lauria rugulosa (Morel.). PL 15, fig. 5. 



Shell rimate-perforate, oblong, closely rib-striate, opaque, 

 brown, scarcely shining, at the base buff and obscurely two- 

 banded. Spire cylindric, shortly tapering, obtuse. 5 

 slightly convex whorls, separated by an impressed suture, 

 the last whorl compressed at base, subangular around the 

 umbilical crevice. Aperture vertical, semi-ovate, 3-folded: 

 2 lamellae on the parietal wall, the right one [angular lam- 

 ella] projecting, joined to the lip by a thin callus, the left 

 one [parietal lamella] further within, smaller: 1 rather 

 strong columellar lamella. Peristome somewhat lipped, nar- 

 rowly expanded, the right margin somewhat sinuous, lightly 

 calloused above the middle. Length 3%, diam. 2 mm.

Of the single specimen collected Morelet writes : 

 " A pretty species, distinguished by the close raised and 

 regular striae ornamenting it. This Pupa is neither glossy 

 or transparent. It is of a uniform chestnut-brown color ex- 

 cepting the last whorl, where the base is yellow and shining. 

 This part of the shell contrasts the more conspicuously with 

 the spire because the general tone is strengthened at its 

 border by an indistinct zone of darker color. A second zone 

 marks the dorsal groove produced by the compression of the 

 last whorl of the spire around the umbilicus ; both of these 

 bands appear distinctly in the interior." 



Morelet does not mention any palatal fold, but his figure 

 (here reproduced) seems to show a lower-palatal. 



54. Lauria vermiculosa (Morel.). PI. 15, fig. 8. 



Shell rimate-p erf orate, ovate, obtuse, vermiculose-ribbed, 

 corneous, opaque, with little gloss, buff-rufescent. Spire 

 obtu.se, short. 5 slightly convex whorls separated by a deep
