FROM THE DEEP BORING AT RICHMOND. We 
at the ends more or less completely, with considerable difference in 
their mode of convergence. Sometimes they meet at the ends of 
the valves, but in some cases run separately to one or the other 
end-margin. 
Cythere bermude, G. 8. B., ‘Challenger Report,’ p. 90, pl. 21. 
fig. 2, is one of the species having the same kind of sculpture. We 
name this fossil species after our friend Dr. G. 8. Brady, F.R.S., 
whose careful and successful researches are well known. 
12. CyrHERELLA suBovaTa, sp. nov. (Pl. XXXIV. fig. 43.) 
Ovate-oblong carapace; smooth, glossy, convex at posterior 
third ; broader (higher) behind than before. This is near the Cre- 
taceous C. ovata (Romer). 
13. OyrHERELna JuGOsA, sp. noy. (Pl. XXXIV. fig. 44.). 
Valve depressed ; faintly ridged near the margin and almost all 
round, with an interval and a knob at the postero-ventral region ; 
also bearing a low curved ridge and a little tubercle on the flat 
medial area of the valve. There are approximations to this in 
Jurassic * and other Cytherelle, but nothing exactly the same. 
C. Williamsonana, Jones, from the Chalk (Cret. Entom. 1842, pl. 7. 
fig. 26 f) has something like the pattern of C. jugosa. 
14. A broken Cythere?, and a little peach-stone Cythere?; both 
obscure. 
Miscellanea of § III. 
Small, tuberculate, claviform Echinoderm spine. 
A subeylindrical and a cylindrical rolled granule, obscure. 
Of the Microzoa from the lowest stratum (§ IIT.) searched, namely 
at 1205 feet, some of the Foraminifera (Nodosarians—Vrondicularia, 
Vaginulina, Marginulina, Cristellaria) are small, and look like 
those of the Lias, but are not peculiar to it, being found in the 
Lower Oolite andelsewhere. Both these and the other Foraminifera 
are of very wide range in time and space ; but one only (Cristellaria 
rotulata) is actually present in each of the little portions of strata 
from the three particular depths noticed in the boring; but its 
close ally, C. cultrata, has turned up in two of them, § I. and § ITI. 
Ten out of the eleven Ostracoda are apparently hitherto unknown 
forms; but they belong to well-known groups, and differ from 
others mostly in slight details. Cytheridea subperforata comes also 
in § II, and Cythereis quadrilatera in § I. The Bairdie of 
§ III. are different from those of § II. 
In a general view of the Foraminifera and Ostracoda obtained by 
Prof. Judd from the three special depths (§ I. 1145' 9" to 1146’ 6’; 
§ IL. 1151’ to 1151’ 6”; and § III. 1205’) in the deep boring at 
Richmond, they do not present any very special characteristics 
recognizable as belonging to particular horizons. The Foraminifera
