ViTREA (Polita) Tomlini, n.sp. 



Testa depressa, orbicularis, perspective umbilicata, supra fuscescenti- 

 cornea, infra pallida, subpellucida, polita, lineis incrementi tenuissimis 

 striata, striis permicroscopicis spiralibus coufertis sculpta ; spira de- 

 pressa, ad apicem vix elata ; anfractus 5-5^ leviter couvexi, ad suturam 

 linea angusta pallida marginati, ultimus ad peripheriam compresse 

 rotundatus, antice baud descendens ; apertura oblique lunata ; peristoma 

 tenue, ad insertiouem prope umbilicum vix dilatatum vel reiiexuiu. 

 Diam. maj. 14, min. 12 5 mm. ; alt. 5 mm. 



Hob. — Pass of Tbermopylae, under stones in the bed of a dried-up 

 torrent. 



Six specimens of this species were collected by Mr. J. E,. Le Brocton 

 Tomlin at the above locality in April, 1903. Although very like some 

 other forms in general appearance, still on close examination the 

 present species appears to be separable. In comparison with the well- 

 known V. lucida of Draparnaud it is seen to be a trifle flatter, the 

 spire more depressed, the whorls more convex, and consequently the 

 suture is deeper. The umbilicus is a little broader, and the microscopic 

 spiral sculpture, although excessively minute and only visible under 

 the microscope, is more apparent than in lucida. The last whorl in 

 the latter is also a little broader than that of the present species, and 

 consequently the form of the aperture is different. I have much 

 pleasure in associating with this species the name of its discoverer. 

 He submitted it to Dr. Boettger for determination, who kindly replied 

 concerning it, " Ahnliche Arten sind weder aus Griechenland be- 

 schrieben, noch finden sich solche in meiner Sammlung."
