1871. On May 24th, 1871, J. Logan Lobley read a paper on the "Principal 

 Features of the Stratigraphical Distribution of the British Fossil Lamellibran- 

 chiata," in which he gives tables and diagrams indicating the number of species 

 of each family of Carboniferous Lamellibranchiata then known from British 

 strata; 'Quart. Journ. GeoL Soc.,' vol. xxvii, pp.411 — 418. He enumerates 

 eighteen genera with 403 species. In Tables ii and iii he gives 398 species, 282 

 of which belong to the Asiphonidse, and 116 to the Siphonidse. 



1871-6. In 1871 Messrs. Young and Armstrong prepared an elaborate 

 catalogue of the Carboniferous Fossils of the West of Scotland, which was 

 published in 1871 as an appendix to vol. iii of the ' Transactions of the Geological 

 Society of Glasgow.' This was published as a separate volume in 1876, on the 

 occasion of the visit of the British Association to Glasgow. One hundred and 

 twenty-five species are enumerated, belonging to twenty-nine genera, and a long 

 and full list of the localities where each species is found is also given. Nothing 

 new is described. 



1871. Vol. iii of the ' Palseontologia Indica ' (Memoirs of the Geological 

 Survey of India), " The Cretaceous Fauna of Southern India' by F. Stoliczka, 

 published in 1871, contains a synoptical list of the families and genera noticed 

 in the volume. In it the Carboniferous genera of Lamellibranchs (Pelecypoda) 

 published up to that date are entered with the type-species, recent and fossil. 

 They are grouped in ten orders and forty-six families. Critical notes are also 

 given. Further researches have, however, in certain cases shown the error of 

 some of these references.
