ORCULA. 29

 p. 59, pi. 14, f. 9-96. 



Kobelt's figures and description of Cyprus specimens are 

 given above, as no shells from Cyprus are accessible to me. 

 Mousson's definition was quite inadequate, but his form has 

 generally been placed under orientalis of Syria as a synonym 

 or variety. Until further comparison can be made, including 

 an examination of the internal structure, the status of the 

 several forms following remains uncertain. 



10a. Orcula. s. orientalis ('Parr.', Pfr.). PI. 5, fig. 5. 



Shell long-rimate, subcylindric, rather solid, obliquely stri- 

 atulate, silky, corneous. Spire thickened above, the vertex 

 mucronulate-convex. Whorls 10, the upper 5 a little convex, 

 rib-striate, the rest flattened ; the last whorl not reaching one- 

 third of the total length, somewhat ascending in front, rather 

 compressed basally. Aperture oval, with a compressed, deeply 

 entering parietal lamella; columella biplicate above. Peri- 

 stome thin, the right margin slightly expanded, columellar 

 margin dilated. Length 12, greatest diam. (near apex) 5 

 mm.; aperture with perist. 4 mm long, 3y± wide (Pfr.). 



Nazareth (Parreyss). Said to occur in Syria and the 

 Lebanon.

Reinhardt (1880) writes that the true P. orientalis has a 

 club-shaped shell, which ranges it in the doliolum group. Its 

 nearest relative is mesopotamica Mousson, which is consider- 

 ably smaller, with more convex whorls. 



Naegele (1902) reported numerous recent specimens from 

 Akbes in Syria, differing from typical orientalis by their 

 great size and single coluniellar lamella. Boettger, with the 

 same material, states that all the examples have two well- 

 developed columellar folds. Length 10, diam. 4.5 mm.
