LEPTOTHYRA. 261 



Von Martens (Xachriclitsbl. d. JNIal. GeselL, 1878, p. 88,) consid- 

 ers this species the same as Leptothyra sanguinea Carp, {non Linn.) 

 -= L. carpenteri Pilsbry. The al)ove description, translated from 

 the original one of Philippi, shows it to belong to an entirely differ- 

 ent group of species — tliat of L. Iceta Montrouzier ; and it may in- 

 deed be nothing more than a bright colored example of that species. 

 At all events, nothing of the sort has been found upon the Califor- 

 nian coast. 



L. MUNDA A. Ad., 1873. PI. 57, fig. 53. 



Shell depressed turbinate, solid, narrowly umbilicate, white, stri- 

 gate and maculate with pale fulvous ; whorls 4, convex, angulate 

 above, finely striate, spirally lirate, the lirre larger at periphery; 

 aperture circular, peristome varicose, deeply crenate ; base slightly 

 convex ; umbilicus with a crenulate nuirgin. 



Alt. 4, diam. 4 mill. 



Persia/I, Guff. 



I have not seen this species. It is apparently related to the fol- 

 lowing. 



L. ARsiNOEN.SLs Issel, 18Gi>. PI. 58, fig. 61. 



Shell small, rather solid, orbicular conoid, depressed, narrowly 

 perforate, white, granulose above; spire very obtuse, apex planu- 

 late ; suture slightly impressed; whorls 3o, the last angulate, en- 

 circled by three conspicuous costa^ ; base minutely concentrically 

 costulate ; aperture subrotuud, right margin arcuate, acute, columella 

 nearly straight, much thickened ; umbilicus narrow, nearly closed, 

 bounded by a crenulated margin. Alt. IV, diam. 21 mill. 



Bed Sea. 



My description is taken from Issel. He says : " Of this species I 

 have seen but a single subfossil example." 



L. EROOPOLITANA Issel, 1869. PI. 58, fig. 60. 



Shell small, somewhat solid, orbicular-conoid, subj^erforate, white,, 

 with very fine elevated longitudinal strife ; spirally costulate ; apex 

 obtuse ; whorls 4, rapidly increasing, angulate above, separated by 

 a distinct suture, the last with three spiral lirse, obscurely angulate 

 at base ; aperture subtetragonal, over half the length of shell ; base 

 slightly convex, concenLrically cingulate ; operculum white, calca- 

 reous, convex outside. Alt. 2-2, diam. 2i mill.
