2. " On some Additional Fossils from the Lingula-flags." By 

 J. W. Salter, Esq., F.G.S. With a Note on the Genus Anopo- 

 lenus; by Henry Hicks, Esq., M.R.C.S. 



In a recent paper Mr. Salter described the new genus Anopolenus 

 as a blind Trilobite allied to Paradoxides, without facial sutures or 

 head-spines, and with truncate body- segments not produced into 

 spinous appendages, as in most of its congeners. The remains of a 

 new species, provided with extraordinary free cheeks, have proved 

 that this conclusion was founded upon a part only of the head and of 

 the body of the animal, which now appears to be more truly inter- 

 mediate between Paradoxides and Olenus than was before supposed, 

 while at the same time it presents characters opposed to those of 

 either genus. 



Mr. Hicks gave a full description of the genus as now known, 

 and of the new species, which he called Anopolenus Salteri. From 

 his description it appears that Anopolenus possessed minute eyes, a 

 facial suture, and expanded pleurae, but that their arrangement was 

 abnormal. 



In conclusion Mr. Salter compared the two species of Anopolenus 

 now known, stating that the one first described, without the more 

 anterior of the two segments which compose the head, was to all 

 appearance a perfect Trilobite. He also gave a figure of a new 

 species of Olenus — 0. pecten. 



3. " On the Discovery of a New Genus of Cirripedia in the 

 ' Wenlock Shale of Dudley.' " By Henry Woodward, Esq., F.G.S. 



The attention of the author having been called to two species of 

 Chiton described M. de Koninck from the Wenlock Shale, he found 

 one of them {Chiton Wrightianus) to be a Cirripede. He stated 

 that the distinctive characters of Chiton are : — (1) The valves never 

 exceed eight in number; (2) the series is always unilinear ; (3) the 

 valves are always symmetrical, and divided into three areas. The 

 species mentioned does not, however, conform to any of these 

 characters, as it had probably as many as four rows of unsymmetrical 

 plates, having no apophyses, a uniformly sculptured surface, and not 

 divided into three areas ; each series exceeded eight in number. 



Mr. Woodward then endeavoured to show that Chiton Wrighti- 

 anus was really a Cirripede, and formed the type of a new genus, to 

 which he gave the name Turrilepas. 



4. " On some new species of Euteryprida." By Henry Wood- 

 ward, Esq., F.G.S. 



In his Advanced Text-book of Geology, Mr. Page figured and 

 named the only known species (S. Powriei) of his new genus Stylo- 

 nurus, but gave no description of it. Mr. Woodward now described 

 the species in detail, from specimens found near Pitscandly, in the 

 Turin Hill Range, Forfarshire ; he also gave a description of a new 

 species (S. Scoticus) found in an Old Red Sandstone quarry in Mon- 

 troman Muir, near the Forfar and Montrose Pike. Mr. Salter has
