square pits; suture deep, with a spiral line, and very finely latticed, 

 last whorl with three keels, and finely spirally striated below ; 

 columella slightly curved ; aperture quadrately ovate ; outer lip 

 simple (J. B.). 



Long 2, broad | mm. Two specimens. 



This species is very much like Eidimella cingulata, Issel, from 

 the Red Sea (J. B.). 



47. Odostomia LiEvrs, Angas. One specimen. 



48. Odostomia Kreffti, Angas. Five specimens. 



49. Odostomia sp. Three sea-worn and imperfect specimens. 



50. Odostomia indistincta, sp.no v., Braz. (PL xiv. fig. 7). 

 Shell ovately conical, whitish, smooth, shining ; whorls 5, 



slightly convex, last whorl ventricose, white below, sutures 

 channelled ; aperture ovate ; columella fold small, situated some 

 distance within the aperture ; outer lip rounded, simple. 



Long 2^, broad 1 mm. Ten specimens. 



This species has the fold on the columella so small that it can 

 scarcely be seen with an ordinary lens when looking directly into 

 the aperture. It can be plainly seen if the shell is placed at a 

 slight angle when looking directly at the columella (J. B.). 



51. Odostomia (Pyrgulina) Henni, sp.nov., Braz. (PI. xiv. fig. 8). 

 Shell fusiformly turreted, solid, dull white ; whorls 6, apical 



one mammillated and smooth, strongly and closely longitudinally 

 ribbed, interstices with minute transverse strife, ribs terminating 

 at the periphery where there is one deep spiral groove, smooth 

 below ; whorls somewhat tabled at the sutures ; aperture small, 

 ovate ; columella-plait transverse, rather sharp and thickened 

 below, outer lip thin. 



Long 4, 4|, broad 1-1-mm. Seven specimens. 



This species may very easily be recognised by its stout ribs, 

 smooth base, and the deep spiral groove at the periphery, and its 

 pagoda-like appearance at the sutures (J. B.).
