ENGLISH UPPER SILURIAN OSTRACODA. 147 



tulosa was obtained, and the scarce Pontocypris 

 Smithii was of frequent occurrence. 



13. Wenlock Railway-cutting, near Much Wen- 

 lock. — Railway -cuttings through fossiliferous rocks 

 always form a good hunting-ground. The ordinary 

 collector is deterred from trespassing, and accord- 

 ingly the spoil from such places is sometimes rather 

 abundant. Small Brachiopoda were common in this 

 fine yellowish shale. There were also a few examples 

 of Spii'orhis, and some Polyzoa. 



Ostracoda, 24 species. The very rare Beyrichia 

 Kloedeni, var. intermedia with big lobe, the scarce 

 Beyrichia Maceoyiana, Bollia bicollina, the rare 

 Thlipsura tuberosa, and the scarce ^chmina ciispi- 

 data, were obtained in this gathering. 



14. Shadwell, near Much Wenlock. — The shale 

 over Wenlock Limestone contained small masses of 

 cubical iron pyrites, some well-rounded quartz-grains, 

 white crystalline masses of calcite, some small 

 quartz crystals, transparent and opaque calcite, a 

 few scales of dark-brown mica, seven pearls, Poly- 

 zoa and Crinoid remains (common), small Brachio- 

 poda (rare), a bone of an Archceocidaris, and a spicule 

 oi Astrceospongia patina, Roam, Many of the minute 

 fossils from this gathering were very white, and con- 

 sequently of a beautiful appearance. 



Ostracoda, 10 species, which call for no special 

 notice. 



15. Norris Quarry, near Wenlock.— The yellowish 

 shale from this quarry contained crystals of calcite 

 as clear as Iceland-spar, small well-rounded masses 

 of crystalline calcite, and rounded quartz-grains. 

 Polyzoa were common and Crinoids frequent. Six 

 pearls were obtained. 



Ostracoda, 15 species. Beyrichia Kloedeni sub-var. 

 clausa, and Cythere Hollii, were frequent. 



16. Bradleyfleld, near Buildwas— Shale yellow- 

 ish, with a few well-rounded quartz-grains, minute 

 iron pyrites, clear and crystalline calcite, Polyzoa
