J. Smith — TJ. Silurian Entomostraca. 71 



Eashall Canal. It turned out rather poor, only a few Braclnopods 

 having been got besides the Entomostraca mentioned in the list. 

 One species of Entomostraca. 



2. Sedgley. — Wenlock-Limestone Shale. This fine yellowish 

 shale yielded several species of small Brachiopods, some fragments 

 of Crinoids and Polyzoa, but was by no means rich in Microzoa. 



Two species of Entomostraca. 



3. The Wken's Nest, near Dudley. — The gathering of shale 

 from this locality was particularly rich in small Brachiopods. 

 Fragments of Crinoids were not uncommon. A few pieces of 

 Polyzoa and some Spirorbes turned up. 



Three or four species of Entomostraca. 



4. Dudley-Castle Grounds. — This gathering contained a number 

 of small Brachiopods, and fragments of Crinoids, Polyzoa, and 

 Tentaculites. 



Three species of Entomostraca. 



5. Dudley-Tunnel Debris. — The Microzoa in this lot were 

 mostly small Brachiopods. This is a good locality for the collector 

 of the larger Silurian fossils, if he likes to dig into the shale-heaps. 

 We have seen splendid specimens of Corals, etc., from this place, 

 such as the Chain, Pipe, Honey-comb, Sun, and other Corals. 



Four species of Entomostraca. 



6. Eailway-Cutting, Coalbrookdale. — This gathering, a fine 

 yellowish shale, was exceedingly rich in Microzoa, including an 

 abundance of Entomostraca. Small Brachiopods were plentiful, 

 Crinoids common (more than 30 small -'heads" turned up), several 

 specimens of small rugose Corals and Polyzoa. Fragments of the 

 eyes of Trilobites, showing both the inside and outside of the facets, 

 were not uncommon. Small specimens of Tentaculites were 

 frequent. 



Three or four species of Entomostraca. 



7. Eailway-cutting by the side op the Severn near Iron- 

 bridge. — This section is exposed in the railway-cutting on the west 

 side of the river, nearly opposite the Swan Hotel. The shale in 

 the cutting lies about 150 feet below the Benthall-Edge Limestone 

 (Wenlock). It is richer in Entomostraca than any other Silurian shale 

 which I have examined. As usual, small Brachiopods are common. 

 Eemains of Crinoids and Polyzoa not unfrequent. 



Eighteen or more species of Entomostraca. 



8. Benthall Edge. — This picturesque locality should not fail to 

 be visited by the student of Silurian Palasontology. Here abundance 

 of the larger Silurian fossils are always to be obtained. Corals, 

 Brachiopods, and Gasteropods are common ; and good Trilobites 

 sometimes turn up to the diligent searcher. With the Microzoa 

 the Brachiopods, as usual, predominate. Crinoidal remains are 

 frequent. Some small Gasteropods and a few Spirorbes occmTed 

 in this gathering. 



Four species of Entomostraca. 



9. Lincoln Hill. — This locality is exactly behind the Swan Plotel, 

 Ironbridge. Small Brachiopods and Crinoids are frequent. A few
