these are more crowded, but on the earlier wliorls more spaced. 

 Undei- high magnificatioii, the iuter-laraellate spaces are seen to 

 be reticulated by very fine spiral and radial striae. Aperture 

 lunate, lip simple, thin, a slight glaze advanced on the body-whorl. 

 Umbilicus one-third of the diameter, exposing the previous wliorls, 

 basin-shaped, steep-sided, broad-based. Height, 2-6; maj. diani., 

 5'5; min. diam., 4:-2mm. 



The original of this description was found bv Mr. Jackson, in 

 August, 1908, undei' a log in the forest, just outside Springs 

 Scrub, Mount Larcombe, Port Curtis. From other material, I 

 lind that it is common in the Port Curtis district, and ranges 

 thence south to Brisbane. 



Endodonta austera, sp.nov. 



(Plate ix., figs.52, 53, 54.) 



Shell small, thin, discoidal, spire slightly sunk below the 

 vertex. Whorls four and a half, well rounded, parted by deeply 

 impressed sutures, last half whorl slowly and gradually descend- 

 ing to about one-quarter of the depth of the penultimate. Colour: 

 variovis shades of uniform brown, from dark chocolate to pale 

 cinnamon, the apex sometimes uniform with the rest of the shell, 

 s(mietimes slate-pui-ple. Sculptui-e : apex smooth, subsequent 

 whorls crossed by delicate radial riblets, which become regularly 

 closer as growth proceeds; on the last whorl, there are about one 

 hundred and thirty riblets, while the preceding whorl carries 

 about half as many; fine radial and spiral scratches ornament the 

 interstices of the riblets. Aperture lunate, lip simple, callus on 

 preceding whorl thin, not concealing the riblets. Umbilicus 

 about one-quarter of the shell's diameter, steep-sided, exposing 

 ))revious whorls. Height, 2; maj. diam., ^•65; min. diam., .'Mmm. 



Hab. — Under logs in the forest, near Logan Village(type), and 

 at Pine Creek Scnib, near Canungera, South Queensland; numer- 

 ous specimens. 



This appears to be one of the common species round Moreton 

 Bay. It is one of several which have been confused by collectors 

 with E. udoidea Forbes. The novelty is darker, smaller, flatter, 

 and more densely ribbed than that species.
