CYPR^EA. 181 



interrupted bands or zigzag rusty-brown flashes. In its growth, 

 this species exhibits a curious variety in the style of coloring. 

 It is first chestnut, the color then breaks up into close-set waved 

 blotches, then a coating of white follows, upon which is deposited 

 a series of zigzag flames. There is a second layer of white 

 enamel which nearly obscures these zigzag markings, and a 

 number of dark spots are deposited. These are again over- 

 spread by a third white coating intermixed with numerous rich 

 black and brown spots. The soft parts adhere so firmly to the 

 shell that they cannot be removed until decomposition has taken 

 place.

New South Wales. 



Dr. J. C. Cox, in Proc. Linn. Soc. N. S. W., for 18 7 9, reported 

 an almost pure white variety from Circular Head, N. S. W., for 

 which he proposed the varietal name alba. 



C. LEUCODON, Brod. PI. 12, figs. 69, 70. 



Reddish or yellowish brown, sprinkled here and there with 

 rather large round white spots, base pale brown, marked trans- 

 versely with fine striae, teeth white, strong on both sides. 



Length, 3-4 inches. 



Habitat ? 



The only specimen known is in the British Museum. The 

 broad teeth and deeply undercut interstices are very like those 

 of C. sulcidentata.
