3. Little JJrswicJc. — At the waste-lieaps of an abandoned ironstone- 

 pit, in a field just to the east of Little Urswick, Furness, are quanti- 

 ties of a light-grey and reddish shale, containing a few Ostracods. 

 The shale belongs to the Yoredale series, and is full of Crinoidal 

 stems, with Fenestella and other Pol^'zoa, and Molluscan fossils. 

 Fragments of a similar shale are seen on some waste ground, by the 

 side of the road, just to the south-east of the village. This material 

 looks like a very suitable rock for Ostracoda, but several boilings of 

 it have only yielded the following species :

Leperditia Okeni (Miinst.).

 * Bairdia plebeia, Eeuss. 



4. Scales Green. — An exposure of dark shale is seen on the north 

 side of the pond (the water being low) at Scales Green, at the east 

 end of the village of Scales, in Furness. Crinoids and other marine 

 fossils are common in the shale, which apparently belongs to the 

 Yoredale series, though the ground is coloured as Carboniferous 

 Limestone in the One-inch Map of the Geological Survey. The 

 Ostracoda are small and not very plentiful : —

5. Gleaston Castle. — The species mentioned below are from the 

 slialy partings of a dark-grey limestone seen in an old quarry on 

 the east side of the road a little to the north of Gleaston Castle, in 

 Furness. The position of the limestone is said by the Geological 

 Survey authorities ^ to be at about the base of the Yoredale Rocks. 

 The shale is rich in fossils, especially in Polyzoa.

6. The only other locality where we have found Entomostraca is in 

 pebbles from the Drift, as seen on the coast to the north of Alding- 

 ham. In one of these Kirkbya Fentiiana, Jones, was peculiarly 

 abundant, as good impressions. Species of Cythere and Bairdia 

 occurred with it. 



In the accompanying Table the distribution of the species in the 

 Scar-Limestone and Yoredale Rocks is shown, as well as their 

 occurrence elsewhere in the North of England and in Scotland.
