LKVTOTHYRA. I>li1 



Von Martens (Xachrichtsbl. d. Mai. (JeselL, 1878, p. 38,) consid- 

 ers this species the same as Leptothi/r<t .^uHjinn^t. Carp, (non Linn, t 

 = L. ctn-jicnff-ri- Pilsbry. The above description, translated from 

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

 ent group of species that of L. lia 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. MI-ND.V A. Ad., 1873. PL 57, fig. 53. 



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

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

 above, finely striate, spirally lirate, the lira? larger at periphery; 

 aperture circular, peristome varicose, deeply crenate ; base slightly 

 convex ; umbilicus with a crenulate margin. 



Alt, 4, diam. 4 mill. 



Persian, Gulf. 



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

 lowing. 



L. AKSINOKNSIS Issel, I860. PL 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 3^, the last angulate, en- 

 circled by three conspicuous costa? ; base minutely concentrically 

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

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

 bounded by a crenulated margin. Alt. 1}, diam. 21 mill. 



Red Sea. 



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

 have seen but a single subfossil example." 



L. EROOPOLTTAXA Issel, 1869. PL 58, fig. 60. 



Shell small, somewhat solid, orbicular-conoid, subperforate, white, 

 with very fine elevated longitudinal striae ; spirally costulate ; apex 

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

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

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

 slightly convex, concentrically cingulate ; operculum white, calca- 

 reous, convex outside. Alt. 2J, diam. 2? mill.
