Hob. Bourke, Darling River, New South Wales {Brazier). 



This species in general appearance is considerably like 

 H. Broughami, Angas, and //. Angasiana, Pfeiffer. The 

 banding is exactly the same as that of the latter species, but 

 its epidermis is yellower. It is also distinguished by its less 

 globose form, smaller body-whorl, its more glossy surface, 

 especially the under surface, the much smaller umbilicus and 

 much thinner peristome, and a different granular sculpture 

 on the spire. H. Broughami has an additional brown band 

 below the periphery, has a finer granulation above, the umbi- 

 licus is more open and surrounded by a coloured zone, and 

 the aperture is wider. H. Stutchburyi, Pfr., is a smaller 

 form, more finely granular above, and in the type the spiral 

 zones are much narrower than in the present and the two 

 above-named species. 



7. Helicina woorflarkensis, sp. n. 



Testa parva, breviter trochiformis, solidiuseula, pallide corneo-lutea, 

 concolor, inferne nitidior quam supra, undique spiraliter tenuiter 

 sulcata, lineis incrementi obliquis striata ; anfract. 5, celeriter 

 creseentes, subplani, ultimus in medio acute angulatus, infra con- 

 vexiusculus, callo basali pellucido munitus ; spira breviter conica, 

 ad apicem baud acuta ; apertura subobliqua, longit. totius g fere 

 sequans ; peristoma pallidum, mediocriter expansum, operculum 

 fere album, externe leviter concavum. 



Alt. 6 millim., diam. maj. 8^, min. 7 ; apertura 3| longa, 3 lata. 



Hah. Woodlark Island (Brazier). 



This species in form and sculpture is very like H. reticu- 

 lata, Pfr. It is, however, somewhat larger, has no variegated 

 markings, the outer lip is more expanded, and the operculum 

 is differently coloured. H. reticulata occurs at Cape York 

 and other places in North-east Australia. The " Cape 

 Flattering," mentioned by Sowerby *, should of course be 

 Cape Flattery on the North Queensland coast. His figure 

 of that species represents the spire rather too much raised.
