[Mar. 6, 



I have taken it in minute globose and egg-shaped masses, one of 

 which has a spine-like body for an axis. 



Loc. Lower Limestone; Freestone Quarry, Brodsworth, and 

 Hampole. 



Entomostraca. 



1. Cythere (Bairdia) plebeia, Reuss, Jahresbericht der Wetterau. 



Gesell. 1854, p. 67. 



Syn. G. (Bairdia) curta, Jones (not McCoy). 



Several specimens of this species have occurred in the Lower 

 Limestone at Hampole, and amongst them the varieties elongata, 

 Neptuni, and compressa. Also a single specimen of the variety 

 ventricosa at the neighbouring locality of Moorhouse. 



2. Cythere (Baikdia) Schatjrothiana, Kirkby, Ann. & Mag. Nat. 



Hist., ser. 3. vol. ii. p. 329, pi. 10. f. 14; and Trans. Tynes. Nat. 

 Field-club, vol. iv. p. 147, pi. 9. f. 14. 



A single specimen of this species occurred at Hampole. 



3. Cythere (Bairdia) ampla, Reuss, Jahresb. Wetter. Ges. 1854, 



p. 68, f. la, lb. 



A fine example of this species occurred to me in the Lower Lime- 

 stone at Hampole, and has been noticed and figured by Mr. Jones 

 in the Transactions of the Tyneside Naturalists' Field-elub (vol. iv. 

 p. 166, pi. 11. figs. 19 a, 19/). 



Its only other locality in England is in the Upper Limestone of 

 Durham at Byers' Quarry, where it is a rare fossil. 



4. Cythere (Cytherideis) Jonesiana, Kirkby, Ann. & Mag. Nat. 



Hist., ser. 3. vol. ii. p. 432, pi. 11. figs. 1, 2 ; and Trans. Tyne. 



Nat. Field-club, vol. iv. p. 151, pi. 11. figs. 24, 25. 

 Syn. Bairdia gracilis, Reuss (not McCoy). 

 Occurs rarely at Hampole. 



5. Kirkbya Permiana, Jones, Monog. Perm. Foss. of England, p. 66. 



pi. 18. fig. 1 ; and Trans. Tyne. Nat. Field-club, vol. iv. p. 129, 

 pi. 8 a. figs. 1-9. 



I have only met with this species once at Hampole. The specimen 

 found agrees in size and general character with those of the Shell- 

 limestone of Durham ; the sculpture of the valves is well marked. 



The specimens of Entomostraca which I have obtained at Hampole 

 are pretty well preserved, and are generally perfect carapaces*. One 

 of the beds at this locality is very friable, and decays rapidly by the 

 action of the weather ; and it is in the debris thus formed that I have 

 found most of my Yorkshire examples of this class. 



FoRAMXNIFERA . 



1. Miliola ptjsilla, Geinitz, Sp. Verstein. Zechstein. und Roth., 

 p. 6, pi. 3. figs. 3-6. 

 Rather common at Hampole along with the Entomostraca. In 



* The locality of Hampole is so often mentioned in this memoir, and is so well 

 worthy of further search, that I may remark that it refers to a little old quarry 

 by the side of the road leading from Doncaster to Wakefield, a short distance to 

 the west of the Tillage, and not far from the Swan Inn.
