Shell minute, discoidal, concave above and below, colour wbitish, 

 with a few broad streaks of pale brown at irregular distances, some- 

 what shining, thin and semi-transparent. Whorls 5, slowly increasing, 

 somewhat rounded, the first three very narrow, the fourth, much 

 larger, rising to nearly the same level as the last whorl, the last, 

 rising abruptly from its suture, curves a little outward to its summit, 

 from thence to the base it is regularly arcuate, where it curves in to the 

 large umbilical crater; closely ribbed, about 19 per millimetre, ribs 

 directed slightly forward, interstices between the ribs ornamented with 

 fine hair-lines, varying from four to seven ; sutures very deep ; in the 

 penultimate and last whorls the ribs do not extend down into the deep 

 sutures. Spire concave to about one-third of the height, embryonic 

 shell of one and a half whorls, shining, sculptured with very fine con- 

 centric strije. Aperture vertical, concentric, peristome straight, acute, 

 margins convergent, columellar margin descending nearly vertically, 

 not reflected, more widely arcuate than the upper margin. Umbilicus 

 deep, large, nearly half the diameter, showing all the volutions.

Emlodonta vortex, n.sp. 



Type in mv collection. 



Hal.— Toko, near Stratford, North Island (R. M.). 



This shell is very near to -£'. stilantialha, Suter ; it differs in being 

 rather more depressed, the body-whorl not being so large in proportion 

 to the rest of the shell, and in its coloration. From E. Huttoni, Suter, 

 it may be distinguished by the gradually increasing whorls, their 

 greater number, and the wide umbilicus.
