CyPRINA (?) ANTHRACICOLA. (N. Sp.) 



Shell of medium size for the genus, presumably compressed convex 

 normally, though all the specimens that the writer has seen are crushed 

 flat. In this condition they are rounded subovate and very little longer 



than high. The anterior side is short 

 and rounded ; the posterior side a 

 little longer, its extremity subtrun- 

 cate abruptly and somewhat oblique- 

 ly above, and obtusely subangular 

 below. The ventral margin is broad- 

 ly rounded ; the superior border 

 slopes abruptly downward in front 

 of the beaks, and much more gradu- 

 ally so behind them ; the beaks are 

 compressed, slightly depressed, and 

 placed considerably in advance of the 

 mid-length of the cardinal margin. 



Surface marked with very numer- 

 ous and closely disposed, fine concen- 

 tric ridges, or raised lines of growth, 

 and a few much coarser and more 

 distant concentric sulcations. Test 

 thick. 



Fig. 26. — Cyprina{'^) anthracicola. Side 

 view of the most perfect but not the 

 largest specimen collected, of the natu- 

 ral size and shewing the right valve. 

 It is crushed quite flat. 



Hinge dentition and muscular impressions unknown. 



The largest specimen that the writer has seen is sixty-five millimetres 

 long and sixty millimetres high. 



Roof of coal, No. 1 shaft, Nanaimo : two nearly perfect, but crushed 

 and flattened specimens, and four very imperfect ones, all collected in 

 1901, the specimen figured, by the Rev. G. W. Taylor, and the others by 

 Mr. Harvey. 



It is just possible that these specimens may prove to be only immature 

 examples of C. Denmanensis, but their beaks are by no means submedian 

 and their marginal outline seems to be more rounded than triangular.
