STKES : NEW LAND-SHELLS FROM CEYLOlSr. 73. 



but the protoconch in the present form is spirally, and not radiately, 

 striate, as in P. clathratula. 



25. Glesstjla Collett^, n.sp. PI. Y, Fig. 1. 



Testa elongata, tenuis, laevigata, obscure longitudinaliter striata, 

 nitida, brunnea vel fusco-cornea, apice obtusiusculo ; sutura impressa ; 

 anfr. 6-6i, convexiusculi, ultimus \ altitudinis testse sequans ; 

 apertura fere verticalis, lunato-ovalis, margine columellari calloso, 

 pallidiore, oblique truncato. Alt. 8, lat. 2*8 mm. 



Mab. — Ambagamuwa (coll. Mrs. CoUett). 



Allied to G. Sattaraensis, H. Ad. (= G. fusca, H. Ad., nom. prcBocc.)^ 

 which is recorded from " Saharumpore, Ceylon," in the Conch. Ind. ; 

 but I do not know on whose authority. It was described and 

 figured from " Sattara, Bombay," by Adams, and it may be remarked 

 that the figure in the Conch. Ind. (pi. Ixxviii, fig. 4) does not quite 

 resemble that given by Adams (Proc. Zool. Soc, 1868, pi. iv, fig. 10). 

 I expect that the G. Sattaraensis of Dr. Jousseaume, cited from 

 I^uwara-Eliya, is the present species, which is more elongate and 

 slender than the true G. Sattaraensis. 



26. Opeas Pkestoni, n.sp. PI. V, Fig. 4. 



T. subperforata, elongato - cylindrica, translucida, tenuis, cornea 

 vel cereo - cornea, apice obtusiusculo; anfr. 8i, piano - convexi, 

 longitudinaliter lineis incrementibus striati, ultimus -„-o- longitudinis 

 subsequans, sutura bene impressa, apertura elongato-ovata ; peristoma 

 simplex, acutum, margine columellari ad basim breviter reflexo, 

 perforationem fere tegente. Alt. 11, diam. 3 '25 mm. ; alt. ap. 3, 

 lat. ap. 1-8 mm. 



JSah. — Uda Pussellawa (Preston); also 0. Collett, exact locality not 

 stated. 



Knowing how widely the species of this group are scattered, I have, 

 with the kind help of Mr. Smith, been throu.gh the British Museum 

 collection, but cannot quite identify my specimens with any known 

 species. The apex is much more obtuse and the earlier whorls are 

 broader than 0. gracilis, and the shell generally is more cylindrical 

 and not so needle-shaped : it appears to be variable in colour. 

 I have given the dimensions of an average specimen; one found by 

 Mr. Preston measures alt. 14, diam. 4 mm. 



Till recently the only true Opeas recorded from Ceylon was 



0. gracilis, Hutton ; this species was found by Mr. Preston at Galle, 

 Colombo, and Trincomalie. In 1894 Dr. Jousseaume described 



0. Marice; I have not had the advantage of examining a specimen, 

 but from the description and figure it seems suspiciously near to 



0. gracilis. 



27. Cyclophoetts (Scabeintjs) Bkoijn'^, n.sp. PI. Y, Figs, 2, 3. 



Testa late umbilicata, depresse conica, periostraco brunneo-fusco, 

 scabro ornata, lineis elevatis spiralibus et costis remotis notata, in 

 regione umbilicari laevior ; spira subelevata, apice exserto, plicatulo,
