22 TERTIARY ENTOMOSTRACA OE ENGLAND. 



In memory of his early researches in the Crag, we name this species after Mr. 

 Edward Charlesworth, F.G.S.

An oblong valve, with parallel dorsal and ventral margins, and rounded ends. 

 Surface with numerous small, more or less angular pits, arranged in parallel rows. 

 A series of pits, almost independent of the other ornament, follows the semicircular 

 outline of the anterior end, just within the margin. The hinder margin is oblique 

 and toothed. A single valve, associated with Nuvmnvlites elegmis, in a bed regarded 

 as at the bottom of the Barton, or the top of the Bracklesham series, Hunting 

 Bridge, New Forest, was collected by Mr. Keeping. (British Museum.) 



The specimens figured and described as G. angulatopora in the ' Monogr. Tert. 

 Entom.,' 1857, p. 34, are not referable to that species. Figs. 17 and 18 of pi. iv 

 correspond with the form to which we have given the name G. transenna 

 (p. 31); and fig. 18, pi. vi, figured by Bosquet (we think, erroneously) as C. 

 angulatopora of Reuss, we now regard also as a new species, and have named it 

 G. Bosquetiana (see below).

One of the oblong species of Cyfherc, with rounded ends, well-marked hinges, 

 and convex valves, ornamented with a strong reticulation, the longitudinal meshes 

 of which are stronger than the transverse. Just in front of the centre of the 

 valve the meshes show an inclination to assume a concentric arrangement. These 

 features are strongly marked in fig. 18, pi. vi, of the ' Monogr.,' 1857. 



The specimen figured in 1857 was from a Tertiary bed at Colwell Bay (rare), 

 and was re-named in 1887. One valve, occurring with Nummulites elegans, 

 in the uppermost bed of the Bracklesham series, or lowest Barton, at 

 Hunting Bridge, New Forest, has been collected by Mr. Keeping. (British 

 Museum.)
