588 Prof. T. Rupert Jones— Wealden Ostracoda. 
Oxford Clay of the Trowbridge Railway-cutting, Wiltshire, and also 
in a piece of the Oxford Clay of Skye, collected by Messrs. Geikie 
and Young, and there associated with Hstheria. If its freshwater 
habitat in the Hamstead series be a criterion, and if these other 
specimens prove trustworthy, it points to more freshwater or 
estuarine conditions in the Oxfordian Series than are usually 
thought of.

Cypridea Austeni, Jones, Grou. Mac. Dec. II. Vol. V. 1878, pp. 109, 110, 277, 
Pl. III. Fig. 8. 
This oblong Cypridea was figured by Fitton instead of the real 
ovate C. Valdensis, and it has been often copied for the latter. The 
figures in Mantell’s works quoted above are given by him as repre- 
senting specimens from the Wealden beds at Brook Bay, Isle of 
Wight. As such they may be noticed here, although possibly C. 
Valdensis may have been really intended, and the figure copied from 
Fitton by mistake. 
In the same lignograph Mantell gave a figure of Cypridea spinigera 
(after Sowerby’s s dr awing), as having also been got from Brook Bay. 
He also copied his fig. 2 from Sowerby’s fig. 4 in Fitton’s Memoir, 
namely, Cypridea granulosa (Sow.), the same as Cypridea fasciculata 
(Forbes), as an Isle-of-Wight specimen; but that was certainly an 
error, for that species occurs only in the Middle Purbeck beds. See 
Q.J.G.8. vol. xli. pp. 840-342. 
Cypridea Austeni has been found at Peaseworth, in Surrey, and at 
Shotover, near Oxford. 
7. DARWINULA LEGUMINELLA (Forbes). 
Quart. Journ. Geol, Soc. vol. xli. 1885, pp. 332, 333, 346, pl. 8, figs. 30 and 31. 
This little Ostracod occurs in the Weald Clay at Atherfield and 
Sandown; also in some Wealden beds of Sussex and Kent, in the 
Upper and Middle Purbecks of Dorset, and the so-called Wealden 
(Purbeck ?) beds of North Germany. In the Grox. Maa. April, 
1886, p. 147, PI. IV. Figs. 4 a, 6, c, this species is recorded also from 
a Jurassic freshwater bed in Colorado. 
The genus is the type of a separate family according to Brady 
and Robertson, ‘‘ Monogr. Post-Tert. Entom.” 1874, pp. 116 and 140. 
As the name was changed from Darwinella to Darwinula, the family 
name is now Darwinulide. D. Stevenson, B. and R., is abundant in 
the fen rivers of the East of England. 
8. Cyprione Bristovit, JONES. 
Quart. Journ. Geol. Soc. vol. xli. 1885, p. 344, pl. viii. figs. 27, 28, 29, 32. 
An additional occurrence of Wealden Ostracoda discovered by the 
Geological Surveyors in the Isle of Wight is a hardish buff-coloured 
marl, marked “3908,” from the “‘ Wealden Cliff opposite Compton
