BEC0RD8 OF THE AUSTRALIAN MUSEUM. 



SOME NEW OR UNFIGURED AUSTRALIAN SHELLS. 

 By Charles Hedley, Conchologist. 



Several collectors have contributed from the vicinity of the 

 Jenolan Caves a well-marked race of Thersites gulosa. Mr. J. E. 

 Wiburd found it among the playthings and decorations of a bower 

 of the Satin Bower-bird, Ptilinorhynchus violaceus, Vieillot. An 

 account of this, by Mr. A. J. North, has been published by Dr. 

 R. B. Sharpe.' 

 It may be named and defined as follows : — 



Thersites gulosa, Gould, var. depressa, n. var. 

 In texture, colour, and sculpture, normal; but distinguished by 

 greatly depressed spire and consequently wider umbilicus and 

 flatter base. The ordinary faint keel is much exaggerated in the 

 variety. Height, 10 ram. ; maj. diam., 22 mm. ; min diam., 20 mm. 



Natica subcostata, Tenison Woods. 

 (Fig. 1). 

 Ten. Woods, Proc Linn. Soc. N.S.W., ii., 

 1878, p. 263. 

 The accompanying drawing has been made 

 from the type in the Australian Museum. 

 Since it was prepared, Messrs. Pritchard and 

 GatlifF have published illustrations and an 

 impro^ved description of the species from 

 F^g- 1- Victorian material. - 



Trichotropis torcularis, Tenison Woods. 

 (Fig. 2). 



Cingulina torcularis, Ten. Woods, Proc. Linn Soc. 

 N.S.W, ii., 1878, p. 263; Rissoa torcularis, 

 Tate, Proc. Roy. Soc. S.A., xxiii., 1899, 

 p. 234. 



As this species has not heretofore been figured, 

 I have prepared the accompanying illustration 

 ^ from the type, now in this Museum. It seems to 

 rae that T. Woods erred in his choice of the genus 

 and that the species would find a more natural 

 place in Trichotrojns. The shell is 3J mm. in 

 length.
