and Guettare, about the middle of the next century gave much 

 more complete representations. Walcott, in 1775, in his work en- 

 titled " Descriptions of Petrifactions found near Bath," figures the 

 Bradford clay Apiocrinus in the name of Entrochus. In 1811 we 

 have a full and interesting description of this fossil, with excellent 

 engravings, published by Parkinson, and in compliment to him, it 

 is now known by the name of Apiocrinus Parkinsoni. Since his time, 

 many other authors have given attention to the Crinoides, more es- 

 pecially Miller, who in 1821 published his elaborate work entitled 

 "Natural History of the Crinoidea," and the late Alcide d'Orbigny 

 whose admirable "Histoire Naturelle des Crinoides/' is illustrated 

 with very beautiful engravings. The late Mr. Channing Pearce 

 wrote a description of the Bradford clay and of the Apiocrinus, 

 which was read before the Geological Society, May 29th, 1833. 



We are indeed most abundantly supplied with books of reference, 

 but allow me to remark, en passant, that to the geologist no know- 

 ledge of his science is so valuable as that which is the result of his 

 own observation and research. 



In the " Annals and Magazine of Natural History " for 1848, 

 Professor M c Coy gave descriptions of a new species, "the Apiocri- 

 nus exutus:" as however no plates were given, it is difficult to 

 identify the species, and knowing to how great an extent these 

 fossils were liable to changes of form, I am disposed to think that 

 it is a variety only of Apiocrinus Parkinsoni. D'Orbigny figures as 

 a distinct species Apiocrinus elegans, and as this is a form which 

 occurs frequently in the Great Oolite, and is so much more elon- 

 gated than Apiocrinus Parkinsoni, it may probably be retained as 

 a species ; but a larger series of specimens, and a more extended 

 , knowledge of these forms, may lead to the conclusion that this too 

 is merely a variety. Some fine examples of the Apiocrinus elegans 

 are now exhibited from the collection of Arthur Adye, Esq., of this 

 i town. The Bourgueticrinus ooliticus, an animal very nearly allied 

 i to the Apiocrinus, but differing principally in having oval instead 

 I of circular plates in the stem, is added to the fauna of the Bradford 

 clay by Professor M c Coy who described it in the " Annals and 

 1 Magazine of Natural History," 1848.
