ture ovate, outer lip slightly effuse, ear-shaped, somewhat 

 thickened. The whole surface of the shell is microscopically 

 exceedingly finely spirally Urate. 



Eulima Shoplandiy sp. n. (PI. XII. fig. 5.) 



E. testa pyramidali, aciculata, albo-lactea, nitidissima, recta, vel 

 interduin paullum curvata; anfractibus decim vel undecim, 

 quorum apicali vitreo, matnillato, caeteris plauis, politissioiis, 

 semipellucidis ; apertura ovata, labro crassiusculo, simplici. 



Long. 5, lat. 1-75 mm. 



Nearly thirty specimens of a very beautiful semitransparent 

 Eulima, yielding to none of the other species in glassy whiteness 

 and extreme polish, which, while possessing no very marked 

 qualifications, does not seem to agree with any yet described. 

 1 have searched the British Museum collection thoroughly 

 as well as my own, this last being rich in Euliraidje, and also 

 compared it with the descriptions and plates in the various 

 monographs. It seems allied to E. pyramidalis, Ad., and 

 opaca, Sow. ; it is not so stout, and is smaller tiian either. 

 To E. venusta, Pease, a much narrower shell, it has some 

 resemblance, and also is akin to E. pusilla, Sowb. ; but here, 

 again, the species is larger and is always, so far as we are 

 aware, straight. E. Shoplandi is occasionally incurved, 

 though the majority of specimens before us are not so. 



This genus is one of the most difficult as regards specific 

 differentiation, especially as regards the forms with ovate 

 mouths, and it is only after a very patient investigation, in 

 which I have been much aided by the discoverer, after whom 

 I have much pleasure in naming it, that 1 have ventured to 

 add it to the lists. 



A species, till now undifferentiated, which is probably the 

 same as this, is found near Karachi (^F. W. Townsend) . 



Leiostraca constellata, sp. n. (PI. XII. fig. 6.) 



L. testa minuta, fusiformi, vitrea, tenuissima ; anfractibus octo, 

 quorum duobus apicalibus pervitreis, caeteris planatis, apud 

 suturas baud impressis, nitidis, circa medium infra suturas regu- 

 lariter rotundis pmictorum ordinibus constellatis roseis decoratis, 

 ultimo quoque anfractu apud basin hie illic simili modo leniter 

 compresso ; apertura oblonga, labro tenui, simplici, margine 

 columellari fere recto. 



Long. 3*50, lat. 1 mm. 



A most delicate and curious little Eulimoid shell ; its 

 markings are quite unlike those of any species known to
