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 Eulima occurs, of which I have two specimens : 

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

 E. subangulata, Somb, described as being an inhabitant of the Indian Ocean.

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

 curred. It might easily be overlooked for the young of Irawadia trochlearis, 

 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.

 M. testa tenuissima, albida, subpellucida, elongato-attenuata, anfractibus 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 (Actocepyramis , Fischer). The shell is 

 white, subhyaline, whorls 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.

A very small but well-marked shell, its sculpture being distinct. The 

 whorls, six in number, of which two are very small and apical, one turreted 

 being much compressed— almost canaliculate— at the sutures, Below the sutures
