and figs. 5 a,b (figured upside down), var. tumida,

 pi. ii, figs. 29, 30. 



To the localities recorded in the Monographs of 1857 and 1874, we have to 

 add Mundesley, Sidestrand, and near Hitchin (' Geol. Mag.,' 1887, p. 459) ; also 

 the old land-drift at Chesilton (Prestwich), the peat-bed at Tilbury, Essex 

 (Mr. Spurrell) ; and Barnwell, near Cambridge (Mrs. Hughes, ' Geol. Mag.,' 1888, 

 p. 200). (Mus. Pract. Geol, &c.) 



3. ? Candona subtbqualis, Jones, 1857. 'Monogr. Tert. Entom.,' p. 20, pi. i, fig. 9. 



This Post-Tertiary form, from Copford, remains as before. (Brit. Mus.) 



4. Candona Forbesii, Jones, 1856.

This form is nearly allied in general appearance to the recent Cypris {Candona) 

 reptans, Baird. It occurs in the shales of the Upper, Middle, and Lower 

 Hamstead series at Hamstead Cliff, and in better preservation in the pyritous 

 bands of that series. It has been found in the Middle Hamstead Beds at Park- 

 hurst Forest (Borehole, No. 32), Isle of Wight ; also in the shales of the Osborne 

 series at Cliff End, Colwell Bay. Mr. F. E. Edwards met with it in the cliffs at 

 Hordwell. (Mus. Pract. Geol., and Brit. Mus.) 



This is the species referred to by Prof. Prestwich, ' Report British Associa- 

 tion ' for 1846, i Trans. Sect.,' p. 56, as occurring at " Hampstead Cliff, one and 

 a half miles east of Yarmouth ; " and remains still in his collection. It is also 

 probably the species noticed in a freshwater-bed of Hordwell Cliff, Hampshire, by 

 Sir C. Lyell (' Trans. Geol. Soc.,' ser. 2, vol. ii, 1829, p. 291). 



5. Candona Richakdsoni, Jones, 1857.

Another locality for this species is the Woolwich-and-Reading beds of the 

 Railway-cutting near Croydon. See Mr. Klaasen's paper " On a Section at Park 

 Hill, Croydon," ' Proc. Geol. Assoc.,' vol. viii, 1884, p. 241. 



This species, and Candona Forbesii, were referred to the genus Candona on
