. Bulletin - New York State Museum. Science. C y p r i c a r d e 11 a norumbegae median tooth just beneath and in front of the beak on the left valve. Shell substance thick, surface with regular concentric growth lines and sometimes a vague radial fold in the postumbonal slope. Lower Devonic. Dalhousie, N. B. Cypricardella parmula nov. These are small shells of oval outline with an almost uniform convexity, beaks well toward the front and very low umbonal ridge. They are about one third longer than high and are espe- cially noteworthy for the strong development of the umbonal teeth,. Cypricardella parmula which are slightly curved ridges, the median one much the strong- est, bounded by deep sockets and a more subdued tooth above and below. There are no Cypricardellas of this type in the New York faunas where they are chiefly characterized by sharp concentric lines and strong umbonal ridge. Such shells as these are however very closely similar to C. bicostata Krantz and C. elongata Beushausen,^ especially to the former. Lower Devonic. Moosehead lake, a little north of Soccatean point, Me. ^ See Beushausen's figures, op. cit. pi. ii, fig.
