C. PAPUENSIS Hedley. PI. 58, fig. 97. 



Shell globosely conical, imperforate, solid ; color, the hydropha- 

 nous epidermis when wet or oiled is of a rich chocolate color; when 

 dry, a pale yellowish-brown crossed by numerous narrow spiral 

 brown lines; deprived of the epidermis the shell is a pale yellow, 

 with a brown subsutural band, first two whorls purple-blue, interior 

 of shell lustrous pale blue, peristome brown; whorls 5|, convex, 

 regularly increasing, last f of total length ; sculpture, entire shell 

 finely obliquely striated and encircled by microscopic close regular 

 raised lines ; apex obtuse, embryonic whorls 1 1> ; suture impressed, 

 margined; aperture oblique, ovate lunate, peristome slightly re- 

 flected, a thin semi-transparent callus extends over the axis and 

 curves up to the insertion of the right margin. Alt. 55, breadth 38 

 mill. (Hedley). 



The Macleay Museum possesses several examples of this species 

 purchased from Mr. Goldie, who collected them in British New 

 Guinea. Considerable difference in size and form exists between 

 these specimens, none of which are in a good state of preservation. 

 One old and worn shell exhibits on the inner side of the columella 

 a tubercle 10 mm. long and 2 mm. wide. Whether this be a dis- 

 tinct species, the adult form, or merely a variety of the species 

 described above, requires further material to decide. (Hedley.)
