BY H. A. PIL8BRY. 



Chiton Coxi, n. sp. 



Shell oblong, much elevated, carinated ; delicate bluish mottled 

 or blotched with olive-brown, yellow and white ; girdle delicate 

 blue-green, with narrow white bars. Sculpture as in Ch. jugosus 

 Gld., but gi'ooves of the pleura shorter, straighter, narrower, and 

 more spaced. Girdle-scales convex, shining, microscopically and 

 superficially striated, each measuriug about .30 mm. wide. Length 

 13, breadth 7? mm.; divergence, 90 to 110°. 



Port Jackson (Dr. J. C. Cox !) 



This is probably the Lophyrus jugosus of Augas' Port Jackson 

 Catalogue, P. Z. S. 1867. It differs from Goulds' species in the 

 totally diverse color-pattern, etc. 



Acanthochites granostriatus n. sp. 



Elongated, the tegmentum occupying about one third the total 

 width in dry specimens. Valves obtusely keeled, the dorsal ridge 

 indisticntly clouded with whitish, orange and blackish ; side mot- 

 tled in varied patterns with olive and white. Girdle olive, the 18 

 tufts silvery stained with blue or dirty olive. 



Valves distinctly imbricating ; the dorsal areas rather wide, con- 

 vex, distinct but not raised at the edges, having numerous rather 

 weak longitudinal strise. Side areas having elevated pustules 

 arranged radially and connected by opaque lines giving the aspect 

 of radial strice. Tegmentum of post. v. subcircular, the mucro 

 rather acute and elevated, at the posterior third. Length 9, breadth 

 3i mm. Port Jackson and Port Hacking, N. S. Wales (Dr. J. C. 

 Cox!) 



Acanthochites Coxi, n. sp. 



Valves grayish, somewhat mottled with olive and fleshy, the dor- 

 sal areas dark red or marked with olivaceous. Girdle olivaceous. 

 Valves nearly disconnected by spiculose bridges of girdle tissue at 

 the sutures. Dorsal areas longitudinally striate ; sides sculptured 

 with convex pustules elongated radially. Tegmentum of posterior 

 valve subcircular, slightly wider than long, the rather elevated, 

 acute mucro slightly behind the middle. Interior rose colored.
