26 TERTIARY ENTOMOSTRACA OF ENGLAND. 



From the Weybourn Crag of East Runton. Collected by Mr. Clement Reid, 

 F.G.S. (Mus. Pract. Geol.) 



"With this species we connect a variety (Plate I, figs. 4 a, b, from the 

 " Norwich Crag " of South wold), in which the tubercles are not so definitely 

 marked. The places of the two near the ventral margin are occupied by irregular 

 swellings, and the postero-dorsal tubercle is ill-defined. (Mus. Pract. Geol.)

One of the suboblong punctate Gytherse, of a not uncommon shape, but rather 

 more oblique anteriorly than usual. Surface slightly convex, swelling at the 

 anterior third, and posteriorly bearing two separate ridges, which rise near 

 the middle of the valve, and end each in a strong knob at the posterior border, 

 thus forming two long, tear-shaped eminences, instead of the more usual pair of 

 posterior swellings, such as we see in C. bidentata, Bosquet, ' Entom. Tert.,' 1852, 

 p. 72, pi. iii, fig. 9, and several other Tertiary Cytherse. 



From the Norwich Crag, Bramerton ; collected by Clement Reid, F.G.S. 

 (Mus. Pract. Geol.) 



25. Cythere baccata, 1 sp. nov. Plate III, figs. 11a, b, c, d. 



Cythere anoulata (G. O. Sars), var., Jones fy Sherbom. Geol. Mag., 1887, 



p. 389. 



In some of their characters our little specimens agree with Dr. G. S. Brady's 

 definition of C. limicola, Norman ; but in them we also see a strong affinity to 

 G. angulata, Sars : G. globulifera, Brady, and G. concinna, Jones, as described in 

 full by G. S. Brady, are also near allies. 



The specimens under notice are neater and more definitely marked than any of 

 those referred to. The reticulation is better than in angulata, and the tubercles 

 clearer and more symmetrically placed than in limicola. 



Our specimens were obtained by Mr. C. Reid, F.G.S. , from the Norwich Crag 

 of Bramerton and the Weybourn Crag of East Runton (Mus. Pract. Geology.)
