32 DESCEIPTIONS OP ELEVEN NEW SPECIES OF TEEEESTEIAL 



* 7. Choisdeella MULTILIEATA. 



Shell imperforate, globosely conical, strongly spirally lined, 

 interstices rather rough, shining, reddish-brown, whorls 4, roundly 

 convex, suture cancelled, spire conical, apex papillose, base con- 

 vex, very finely marked with spiral lines, aperture vertical, lunate, 

 peristome thickened, margins distant, columella margin straight, 

 thickened with a white callus round the imperforation which is 

 hollowed out, operculum shelly, ovate, smootli, brownish, with a 

 long pointed shelly protuberance on the under side or place of 

 attachment to the animal. 



Diam. maj. f , min. i, alt. 1 lin. 



Hab. Fitzroy Island, north-east coast of Australia ; found 

 crawling on the roots of grass, in company with Dijplommatina 

 gowllcmcli. (Coll. Brazier.) 



This interesting microscopic species I place it in the Genus 

 Chondrella of Pease. Not having seen the description of that 

 Genus, only having specimens of Pease's parva from Eorotonga, 

 one of the central Pacific Islands, which I find comes very close, 

 both in the shell and operculum, to my Australian species, of 

 which I collected some hundreds, I am of opinion that Chondrella 

 is only a synonyme of the Genus Garrettia, O. Sempek. 



8. COLTJMBELLA (MiTRELLA) EuSSELLI. 



Shell cylindrically oblong, somewhat fusiform, smooth, white, 

 whorls 6, moderately convex, encircled with oblique dark orange 

 spots on the last whorl, first row large, below long and reticulated, 

 above the suture arrow-shaped, aperture oblong, ovate, peristome 

 thinnish, irregularly curved, thickened at the upper part with 

 callus, columellar marked with fine grooves, canal short, straight. 



Length 2i, breadth 1\ lin, 



Hab. No. 6 or Eclipse Island, Claremont Group, north-east 

 coast of Australia. I only found one specimen under a stone 

 during our stay of nine days. (Coll. Brazier.) 



9. CoLTJMBELLA (AnACHIs) DiGGLESI. 



Shell oblong ovate, thin, glassy, whitish, marked with oblique 

 reddish lines running from left to right, longitudinally finely ribbed, 

 rounded, whorls 5^, tabled at the suture, apex acute, light blue, 

 aperture ear-shaped, half the length of the shell, outer lip minutely 

 denticulated within, columellar curved, finely striated, callus 

 extendiug up to the upper part of the lip, canal short.
