LIMICCLARIA, N.-E. AFRICA. 279 



Related to L. numidica and the short form of L. heuglini 



(clwana) . 



47. L. OVIFORMIS Ancey. 



Shell covered and minutely rimate, obtuse-oblong, solid, 

 rather opaque, glossy; under a deciduous pale straw-buff 

 cuticle it is gray-white variegated or flammulate with narrow 

 pale brown streaks in the middle whorls. Spire oblong, rela- 

 tively not much attenuate, the apex very obtuse. Whorls 7, 

 convex, regularly and slowly increasing, the suture moder- 

 ately impressed, somewhat irregular; regularly decussate 

 with growth and spiral striae, somewhat spaced; the last 

 whorl oblong, rounded, smooth past the middle (the spiral 

 strioa disappearing). Aperture suboblique, oblong-narrowed, 

 whitish. Columella reflexed, thickened, nearly straight; 

 peristome unexpanded, acute, the outer margin hardly arched 

 forward. Length 44, diam. 21, alt. apert. 18.25 mm. (Ancey").

" It is remarkable in being very obtuse and of an oblong 

 shape. The markings are but faint, at least as far as the 

 original specimen is concerned/' 



It was recorded in the first place as from Arabia, in the 

 mountains above Aden, but this information proved to be- 

 inexact. It is probably related to L. donaldsoni and the 

 immediate allies of that species. 



48. L. DONALDSONI Pilsbry. PI. 28, figs. 29, 30, 31. 



Shell narrowly umbilicate, oblong-ovate, rather thin. Spire 

 short and wide, terminating in a very obtuse rounded apex. 

 Whorls slightly over 6, quite convex, separated by deep 

 sutures. Surface shining, finely striated longitudinally, the 

 strias cut into oblong granules by decussating spiral im- 

 pressed lines, which become subobsolete on the last whorl 

 except below the suture, where they persist, although weaker. 

 Aperture ovate, a little less than half the length of the shell, 

 bluish- white within; outer lip thin and sharp; columella
