under the turf tlie liroestone is rather rotten, and full of Corals and 

 Mollusca ; Ostracods also are plentiful, and as follow — 



*Leperditia Okeni (Miinst.). 

 *L. Arnistrongiana, J. & K. MS. 

 Beyrichia radinta, J. & K. 

 **Kirkbya Fermiana, Jones. 



Cytlierella ? reticulosa, sp. nov. MS. 

 *Cythere^ ? cuneola, J. & K. 

 *Xestoleberis ? subcorbiiloides, sp.n. MS. 



7. Kent's Bank. — From a bed (about a foot thick) of very dark, 

 shivery shale in the limestone cutting on the Furness Railway, a 

 little to the west of Kent's Bank Station. The shale is exposed on 

 both sides of the cutting ; also close to the sea-shore, immediately to 

 the south. The associated fossils are species of Produchis and other 

 Brachiopods, etc. Ostracods are few. 



*Bythoeypris bilobata (Miinst.). 



Argillaicia aqualis, J. & K. MS. 



Bairdia Eisingeri (Miinst.). 



B. ampla, Eeuss. 



*B. curta, M'Coy. 



**B. brevis, J. & K. 



Bairdia Sisingeri (Miinst.). 

 B. submucronata, J. & K. 



Leperditia Oheni (Miinst.). 

 Beyrichia, sp. 

 Cytlierella, sp. 



8. Stainton. — In Stainton Quarry, a mile or so south-east of 

 Dalton-in-Furness, Kirhbya Permiana occurs in shaly partings of 

 the Scar-limestone, associated with Corals. 



II. — Localities in the Yoredale Eocks. 



1. Humphrey Head. — On the west side of Humphrey Head, just 

 to the south of the Holy Well, is about four feet of grey shale, 

 associated with limestone in thinnish beds, and lying rather irregu- 

 larly with a steep dip to the west. Both shale and limestone are 

 fossiliferous, and we take them to be Yoredale beds faulted down 

 against the cliff of Scar-limestone forming this picturesque head- 

 land.^

 *B. plebeia, Reuss. 

 *B. submucronata, J. & K.

Cytlierella Benniei, J. K. & B.

2. Holker Park. — An interesting section of the Yoredale rocks is 

 exposed on the west side of Holker Park, just on the edge of the 

 marshland to the north of Quarry Flat. These beds consist of 

 yellow sandstones, shales, and crinoidal limestones, all dipping 

 sharply about south-south-east. A few Ostracods are found in a 

 dark-grey shale underlying the uppermost limestone ; but they are 

 not numerous, and are very badly preserved. A little further to 

 the north a thick calcareous shale comes in beneath another and 

 lower limestone. This shale is especially rich in Polyzoa besides 

 other fossils. Twelve species of Ostracoda occur in it, all of small 

 size, and none very plentiful.

2 In the One-inch Map of the Geological Survey no Yoredale beds are shown 

 bere ; but tbis is probably due to their having been only recently exposed.
