ENGLISH UPPER SILURIAN OSTRACODA. 143 



Kloedeni var. nuda, the scarce Beyrichia Klcedeni var. 

 clausa, and Bathocypris reniformis, were got. 



5. Sedgely, near Wolverhampton (Wenlock Shale 

 above Limestone). — A fine-grained yellowish shale, 

 with the usual Silurian fossils, some small Brachio-. 

 poda, Crinoids, and Polyzoa. 



Ostracoda, 18 species. 



6. Sedgely (Shale above Aymestry Limestone). — 

 Shale rather arenaceous, with minute scales of white 

 mica, well-rounded quartz-grains, some brown mag- 

 netic particles, some scales of brown mica (biotite), 

 one Lagena, 10 pearls, part of a fish scale, three 

 Conodonts, and worn fragments of Polyzoa. Ostra- 

 coda were rare in all the Aymestry shale I examined 

 and other fossils were by no means common. 



Ostracoda, 2 species. 



7. Lincoln Hill, Ironbridge, Shropshire.— The 



Wenlock strata dip rather steeply here, and the 

 limestone, which is exhausted in the open-cast 

 workings, is now drawn from a pit. This limestone 

 is to a large extent made up of Corals, and, in the 

 cavities of the stone, mineral-grease is not unfrequent. 

 The shale in connection with the limestone is of a 

 yellowish colour, and contains some very minute 

 scales of white mica (muscovite), some particles of 

 black scoriaceous lava, a few well-rounded quartz- 

 grains, rock-milk, iron pyrites, some minute quartz 

 crystals, some transparent and opaque crystalline 

 calcite, some annelid-jaws, three Lagence, one spicule 

 of Astrceospongia patina, Roem., a small spiral, and 

 a bone of Archceocidaris. Small Brachiopoda and 

 Crinoids were frequent, Spirorbis common, and 

 Polyzoa rare. There were also a few rugose Corals. 

 Ostracoda, 34 species. Beyrichia Kloedeni var. tuber- 

 culata, with big lobe, was frequent ; B. Maccoyiana, 

 with big lobe, was also moderately common. The 

 locality is also one of the best for the rare Strepula 

 concenfrica, and ^S. irregularis, and for the very rare 

 Strepula beyrichioides and Octonaria octoformis. The
