 thickened. The whole surface of the shell is microscopically 

 exceedingly fiuely spirally Urate. 



Eiilima Shoplandi, sp. n. (PI. XII. fig. 5.) 



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

 interduin pauUum curvata ; anfractibus deeim vel uudeoim, 

 quorum apicali vitreo, maiuillato, caeteris plauis, politissiiuis, 

 semipellucidi.s ; apertura ovata, labro crassiusculo, siraplici. 



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 Eulimidte, and also 

 compared it with the descriptions and plates in the various 

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

 opaca, Sow.; it is not so stout, and is smaller than 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 tlie 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 miuuta, fusiformi, vitrea, teouissima ; anfractibus octo, 

 quorum duobus apiealibus pervitreis, caeteris planatis, apud 

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

 laritcr rotundis punctorum ordinibus constellatis roseis decoratis, 

 ultimo quoque anfractu apud basin hie illic simili raodo loniter 

 compresso ; apertura oblonga, labro tenui, simplici, margine 

 columellari fere recto. 



Long. 3*oU, lat. 1 mm. 



A most delicate and curious little Eulinioid shell ; its 

 markings are quite unlike those of any species knowji to
