accrcscentes, sntHva profinda chliqna discirti, duo apicales laeves, convexi, 

 supva tabulati, apicem obtnsiim fonnautes, scqiientes 5-6 convexinsculi,

 cvenidaiis scnJpti, ultinius ad pevipheriam angulatus, hand descendens ; 

 apertura anf^ulatini ovalis ; peristoma teniie, simplex, margine coluniellavi 

 angitste reflexo.

This species is remarkable for the peculiar sculpture, con- 

 sisting of close-set slightly oblique raised lines of growth, which, 

 being crossed by numerous transverse impressed striae, have a 

 prettily festooned or crenulated appearance. It differs from 

 S. arguta Martens in sculpture, in the angulation of the body- 

 whorl, and more tapering form. 



8. Stenogyra (Riebeckia) decipiens, n. sp. 



Testa S. socotoranae similis, sed ad apicem magis attemiata, sutiiva 

 hand canaliculata, sciilptura tenuiore, hand cancellata. 

 Longit. 88 mm., diam. 30. Apertura 27 longa.

Although quite similar in general appearance, this species is 

 certainly distinct from 5. socotorana. The top of the spire is 

 more slender, the suture is not deeply cut or channelled, and the 

 sculpturi is much finer, consisting of fine lines of growth and 

 excessively fine spiral striae. It is possible that some of the 

 shells figured by Martens (Conch. Mittheil, vol. ii., pi. xxix) 

 may belong to this species, figs, 'ja, 'jb, and 8 especially having 

 a very striking resemblance to it. 



g. Auricula socotrensis, n. sp. (PI. V., figs. 8, 8aj. 



Testa elongato-ovata, imperforata, olivaceo-fusca, nitida, lineis 

 incrementi tenuibus striata ; spira brevis, convexc conoidea, ad apicem 

 mammillata ; anfractus 7, siipremiis couvexns, caeteri vix convexi, 

 interdum plus minus spiraliter punctati, ultimus elongatus, lateribus 

 leviter convexis ; apertura inverse elongato-auriformis ; labrum tenue, 

 intus levissime incrassatum ; columella quadriplicata, plicis superioribus 

 duobus subconjnnctis et aliis infcrioribus solidioribus. 



Longit. 9, diam. 4 mm. Apertura 7 longa. 



Allied to A. pusilla,ll. & A. Adams, A. nevillii, and gassiest 

 of Morelet and a few other species, but quite distinct.
