112 PKOCEEDINGS OF THE MALACOLOGICAL SOCIKTY. 



allied to the European and British E. inmirva, Renieri, SJ. distorta, 

 Phil, (non Defrance), but the shell is much broader at the base, and 

 the whorls are not so flattened. The mouth is obliquely oblong, and 

 in full-grown specimens the shell is slightly thickened at the columellar 

 margin. Many specimens. 



Another small species of Eidima occurs, of which I have two speci- 

 mens : it is straight, and in form like E. polita, L. ; it may possibly be 

 identical with E. suhangulata, Somb., described as being an inhabitant 

 of the Indian Ocean. 



12. Syenola metria, n.sp. PI. VIII, Pig. 16. 



S. testa elongata, fusiformi, solida, alba, nitida, anfractibus 10, 

 apud suturas acute canaliculatis, rectis, apertura ovato squarrosa, 

 peristomate teni;i, simplice, marginem apud columellarem uniplicato. 

 Long. 5, lat. 2 mm. 



A shining, smooth species, deeply channelled at the sutures. Month 

 squarely ovate, with one columellar plait. In form an Oheliscus, in 

 mouth-process a Syrnola. The name is the Greek /uerpio^, ' moderate,' 

 ' modest.' 



13, OsciLLA Indica, n.sp. PI. VIII, Pig. 5. 



0. testa attennata, fusiformi, delicatula, tenui, semipellucida, 

 Candida, anfractibus 9 vel 10, transversim undique spiraliter 

 tricostatis, costis acntis Itevibus, interstitiis sub lente tenuissime 

 longitudinaliter striatis, apertura oblonga, labro simplice, marginem 

 apud columellarem uniplicato. Long. 3, lat. 1*25 mm. 



A very beautiful little form, of which only one specimen has so 

 far occurred. It might easily be overlooked for the young of Iraioadia 

 troMearis, Blanford, but this is a coarser shell, though of the same 

 transversely carinate pattern and white colour. It is a most delicate 

 species, and the columellar plait, though somewhat deep-seated, is 

 very evident. 



14. Mtonia gavisa, n.sp. PL VIII, Pig. 26. 



M. testa tenuissima, albida, subpellucida, elongato-attcnuata, an- 

 fractibus 7, ventricosulis, undique transversim filostriatis, apertura 

 oblonga, peristomate tenui. Long. 2-25, lat. 1 mm. 



A very small, delicate species, with some appearance of an Aclis, but 

 we consider rightly referable to Myonia {Actceopi/ramis, Pischer). 

 The shell is white, subhyaline, Avhorls probably seven (but the sole 

 specimen is a little broken at the apex), much, ventricose, and 

 uniformly transversely filostriate. The name is the Latin gavisus, 

 ' that has given pleasure,' from the beauty and sculpture of this 

 little shell. 



15. MiRALDA IDALIMA, U.Sp. PI. VIII, Pig. 6. 



M. testa oblonga, gradatula, tenui, albida, subpellucida, anfractibus 6, 

 ad suturas multum impressis, subcanaliculatis, turritis, infra suturas 

 bino gemmarum ordine decoratis, partes ad caeteras anfractuum trans- 

 versim costulatis, ultimo apud basim la^viore, apertura oblonga, labro 

 tenui, marginem ad columellarem uniplicato. Long. 2, lat. 1 mm.
