154 RECORDS OF THE AUSTRALIAN MUSEUM. 



baad ascend tlie spire, callus of the aperture ochraceous. Wiiorls 

 six. Sculpture : close fine spiral threads, crossed by tine growth 

 strite, a stroiig(n' subsutural cord ascends the upper whorls. Base 

 a funnel, surrounded by a strong keel. A stout projecting varix 

 continues the basal keel and sligiitly intrudes upon the suture. 

 Beyond the varix tlie aperture is considerably produced but the 

 ordinary colour and sculpture is not repeated upon this part of 

 the shell. Within the outer lip a projection rises from the base 

 for two-thirds the height of the aperture and there ends abruptly. 

 Midway down the aperture on the left side, at the horizon of 

 the basal keel, is a stout entering plication. The space above 

 and below this is divided by a smaller parietal tubercle and a 

 stronger columella plait. Length, 7*5 ; breadth, 4 mm. 



Hub. — I obtained eight specimens from the roots of mangrove.s 

 near the beach about a mile south of Cooktown, Queensland. 

 The uniformity of the series precludes the idea that the twisted 

 base might be a deformity. 



Papuina muensis, sp. nov. 

 (Plate xliv., figs. 44, 45). 



Shell small, trochoidal, spreading towards the base and thus 

 gaining a concave profile, minutely perforate. Whorls six, rather 

 rapidly increasing, slightly convex and parted by impressed 

 sutures. Colour buff with a narrow zone of chocolate on the 

 p.riphery, continued as asupersutural tliread on the upper whorls 

 and visible within the aperture ; the apex and tlie columella are 

 also chocolate. Sculpiure : oblique irregular growth lines which 

 tend to form knots on the periphery, under the lens appear also 

 close incised waved spiral lines. Aperture elliptical, abruptly 

 descending and very oblique, lip produced and narrowly reflected 

 margins continued and united by a callus ridge. Columella very 

 short and oblique. Base tumid. Umbilicus narrow and oblique. 

 Height, 14; maj. diam., 14; min. diam., 12 mm. 



The nearest^Australian r<datiou to P. miiensis seems to be P. 

 piirttiana, Pfeiifer, fiom Night Island, about one hundred and 

 eighty miles to the st)uth. The latter is far larger, proportion- 

 ately narrower and the aperture is less contracted. The figure 

 oi Helix bertiniana, Tapparone Canefri''^ has some resemblance 

 to the novelty.
