{i.e. Pen-y-gent, Ingleboro, etc.)." Mr. Grarwood adds: "Both of 

 the specimens were much larger, when first exposed in the matrix ; 

 but the rock was so jointed, and the outer whorl [body-chamber?] 

 so hollow, and replaced by calcite crystals, that only fragments of 

 this could be obtained, and a good deal was broken before I could 

 discover the extent of the fossil in situ." 



The close resemblance of the present form to the Temnocheilus 

 coronatus of M'Coy will be apparent to any one acquainted with that 

 species, either through the figure given of it in the " Synopsis of 

 the Carboniferous Fossils of Ireland" (pi. iv. fig. 15), or by direct 

 knowledge of the specimen itself in the Museum of Science and Art, 

 Dublin, M 'Coy's specimen, which came from the Carboniferous 

 Limestone of Little Island, near Cork, is, however, greatly distorted 

 by cleavage, and is apparently immature. 



In his "British Palseozoio Fossils" (p. 557), M'Coy referred to 

 this species some examples from the Carboniferous Limestone of 

 Lowick, Northumberland, and these enabled him to amend bis 

 original description of the species. These specimens are now 

 preserved in the Woodwardian Museum, Cambridge ; one is fairly 

 complete and four are fragmentary. They are all internal casts and

bear only fragments of the test; but upon the inner whorl of the 

 tolerably complete example there is an indication of the longitudinal 

 ornamentation of the test, and this is just as in M 'Coy's type- 

 specimen ; moreover, the dimensions and other characters of these 

 examples agree so closely with M'Coy's type, that we think there
