22. Chickley Common, between "Woolhope and 

 Dormington. — This yellowish shale contained some 

 small white masses of crystalline calcite, some 

 opaque calcite, a few rounded quartz-grains, some 

 minute mica-scales, three LagencB, five pearls, and 

 two specimens of Spii'orbis. 



Ostracoda, ll species. Primitia paucipunctata, the 

 widespread Thlipsura plicata (common), and the rare 

 Octonaria octoformis var. informis, occurred in this 

 eample. 



23. Malvern Tunnel (Blue shale at west end of 

 tunnel). — This shale is greenish-blue in colour, and 

 not so fine-grained as the Silurian shales generally 

 are. It is rather much "barkened" to many of the 

 smaller fossils. It contained scales of mica, minute 

 angular pieces of mica- schist, a few well-rounded 

 quartz-grains, some small aggi*egates of calcite, 

 minute masses of cubical iron pyrites, some small 

 recent calcareous concretions on plant-fibres. Polyzoa 

 were frequent, as well as small Crinoid remains and 

 Brachiopoda, a few casts of very small spirals, some 

 very diminutive rugose corals, numerous minute 

 Tentaculites, a spicule of AstrcBOspongia patina, Rcem., 

 and some specimens of Stachia ? 



Ostracoda, 20 species. The scarce Beyrichia lacunata 

 was frequent ; Primitia valida, frequent ; P. valida 

 var. hreviata, frequent ; Macrocypris elegans, frequent ; 

 Cythere Hollii, frequent. Many of the Silurian 

 Ostracoda are remarkably well-preserved ; and of 

 this I had experience when washing the sample, as 

 two recent fresh-water Ostracoda got mixed up 

 with the Silurian species, and had been mounted as 

 *' fossils" before I detected the error. 



24. Malvern Tunnel (Red shale). — This was from 

 the same place as the last, only a short distance 

 further from the mouth of the tunnel. Like last 

 sample, the shale was coarse, and contained the 

 same mineral particles. From it were obtained a 

 minute spiral, and a spicule of Astrceospongia patina, 

 Roem.
