GKAMMYSIA sp. 

 (PI. XXXI., fig. 3.) 



There is one left valve (No. 214) of a species of Granwii/sia 

 showing the following characters : Shell ovate, rhomboidal ; length 

 more than one-third greater than the height ; anterior end short, 

 rounded ; basal margin gently arcuate ; posterior end broad, obhquely 

 truncated, gently curved above, abruptly rounded inferiorly ; cardinal 

 margin short, nearly straight. Surface strongly convex, most so 

 about middle ; beak sub-anterior, large, prominent incurved, directed 

 forward, scarcely rising above hinge-line ; umbonal ridge strong, 

 gently curved, subangular above, flattened in front and merging into 

 general convexity of shell ; cardinal slope broad, rather flattened. 

 Surface of valve ornamented with 8-10 coarse oblique concentric 

 wrinkles with finer striae between. 



Dimensions. — Length 35 mm. ; height (at middle) 22 mm. 



Affinities. — The shape of this shell resembles that of G. alreata 

 (Conrad) " and G. Urata, Hall,f both from the Hamilton Group, 

 Init in our specimen the ornamentation is continued over the whole 

 surface, and the beak does not rise quite so prominently. G. ovata, 

 Sandberger, :J: from the Coblenz Beds has somewhat similar propor- 

 tions. G. gardneri, Clarke, ^; from the Devonian of Brazil, appears 

 to be allied to our form, and there is much resemblance to G. cJie- 

 mungensis, Pitt.!]

SANGUINOLITES sp. 



(PL XXXI., fig. 4.) 



The right valve of a lamellibranch (No. 98) which should probably 

 be referred to the genus Sanguinolites occurs on the same slab of 

 rock as a good example of Leptocalia flahellites. The anterior end is 

 not w^ell seen, but the beak appears to be near this end, obtuse and 

 directed forwards. The shell is elliptical in shape, not quite twice 

 as long as high, with the basal margin gently curved, the posterior
