outline, broader than long, and its posterior side is produced and some- 

 what pointed below. Nanaimo, V.I., two specimens ; one a very gibbous 

 lower valve, sixty-five mm. long and forty-two broad ; the other, seventy 

 millimetres in length by forty-nine in breadth, with both valves pre- 

 served in situ, but with a much less convex lower valve ; both of them 

 elongate subovate in marginal outline and almost equilateral. In two of 

 the specimens the lower valve is strongly and regularly convex, but it is 

 not lobed posteriorly by a distinct longitudinal groove or sinus on or near 

 the front margin, in either of the three. 



" These free and narrowly convex shells look very different to the 

 broad, irregularly subhemispherical specimens, with a broad surface of 

 attachment to the umbo of the lower valve, from the Fort Pierre group 

 of the Dakota Cretaceous, which Mr. Meek referred with some doubt to 

 0. vesicularis. Still they correspond fairly well with Goldfuss' descrip- 

 tion and figures of the typical form of that species, which he calls the 

 "var. A.," and describes as "testa rostrata libera; " also with Moi'ton's 

 figures of G. convexa, Say, and with one of Stoliczka's figures (Cret. Faun. 

 S. India, pi. 42, fig. 4) of 0. vesicularis" (1896, op. cit. supra).

Two upper valves of a small species of Anomia, that are probably refer- 

 able to A. Vancouverensis, were collected at Texada Island by Mr. Harvey 

 in 1901. Both are irregular in outline and marked only with concentric 

 lines of growth, while the beak of each is very nearly marginal.

The original description of this species is as follows : — - 

 " Shell moderately convex, subovate, with an apparently feebly develo- 

 ped mesial fold and sinus. Ventral valve a little longer than broad, with a 

 narrow, elongated and nearly straight beak ; dorsal valve broader than 

 long, with a comparatively obtuse and incurved beak. Surface markings 

 of both valves consisting of numerous (about twenty-two) narrow, pro-
