CrTHEEE Eeidii, Jones Sf Sherborn. Geol. Mag., 1887, p. 389. 



Valves suboblong, obliquely rounded at the ends, broader in front than 

 behind, straight on the back, slightly sinuous below, nearly flat ; rising into a 

 median knob in the anterior third. Surface covered with very coarse punctation, 

 making a rough reticulation. The nearest published species appears to be 

 Gi/thereis tubereulata, Sars, as figured by G. S. Brady, ' Trans. Linn. Soc.,' vol. 

 xxvi, p. 406, pi. XXX, figs. 26 — 29. 



Our species is named after Mr. Clement Reid, F.Gr.S., who collected this and 

 many other previously undescribed Ostracoda from the Crag Beds of Norfolk. 



From the Weybourn Crag of East Runton. (Museum of Practical Geology ) 



13, 14, 15. Cythere Woodiana, laqdeata, and maokopoka. 



These (' Monograph,' 1857) succeed here in the order of their shape and general 

 relationship. (British Museum.)

CrTUEEE WooDWABDiANA, Jones & Sherborn. Geol. Mag., 1887, p. 390. 



Subtrigonal, obliquely rounded in front, nearly semicircular behind ; broad 

 across the anterior third by the projection of the hinge-joint. Surface slightly 

 convex ; ventral surface somewhat flattened. Superficial ornament, a coarse, 

 irregular pitting, becoming linear and concentric at the ends. 



We name this species after Dr. Samuel Woodward, one of the earliest workers 

 in these late Tertiary deposits.

Mr, Clement Reid has met with a good variety, with less prominent ridges
