12 BRITISH SILURIAN BRACHIOPODA. 
ITALY. 
No Silurian Brachiopoda have, as far as I am aware, been hitherto found in Italy, but 
Prof. Mrnzeutnt, in his admirable work on the ‘ Paléontologie de I’ Ile de Sardaigne,’ Turin, 
1857, describes and beautifully illustrates some sixteen species of Silurian Brachiopoda 
that had been discovered in that Italian island by General Albert de la Marmora. 
INDIA. 
A number of Silurian Brachiopoda from the Niti Pass, in the Northern Himalaya, 
have been described and figured by Messrs. Satter and H. F. Buanrorp (Calcutta, 1865); 
these specimens were collected by Col. R. Strachey (see ‘ Quart. Journ. Geol. Soc.,’ vol. 
Vil, p. 292). 
AMERICA. 
Both Canada and the United States are exceedingly rich in genera and species of Silurian 
Brachiopoda, and these have been well described and figured by many palzontologists. 
Canapa AND Nova Scotta.— Weare especially indebted to Mr. E. Briures, Palonto- 
logist to the Geological Survey of Canada, for many very valuable descriptions and figures 
of Canadian Silurian Brachiopoda. ‘These will be found recorded in publications of the 
Geological Survey of that country,—‘ Paleozoic Fossils,’ vol. i, 1861-65; in the 
‘ Reports’ for 1856-58 ; as well as in various numbers of the ‘Canadian Naturalist and 
Geologist’ for 1859-60; also in the ‘ American Journal of Science’ 1863, &c. Mr. Billings 
has proposed a few new genera amongst the Lower Paleozoic Brachiopoda. 
Some species from the Silurian Rocks of Nova Scotia have likewise been described and 
figured by Prof. J. Hauu,in a paper communicated to the Natural History Society of Montreal 
(‘ Can. Nat. Geol.’), and afterwards republished in Dr. Dawson’s ‘ Acadian Geology,’ 1855. 
Unitep Srates..—No one in America has devoted so much attention to the many 
1 Rafinesque appears to have been the first person (so far as I know) wh6 published anything on American 
Silurian Brachiopoda; but, notwithstanding all the inquiries which I have made in conjunction with Prof. 
Suess, De Koninck, and J. Hall, I have not yet been able to obtain a certain reference to that author’s 
early papers. In the ‘ Annales des Sciences Physiques,’ by Bory-Saint-Vincent, Van Mons, &c., p. 232, 
Brussels, 1820, will be found a memoir entitled “ Prodrome d’une Monographie des Turbinolies fossiles du 
Kentucki,’ in which it is stated, while enumerating the objects collected in America by Rafinesque 
and Clifford, that several genera, such as Madreporites, Favosites, Encrinites, Terebratula, &c., are so nume- 
rous in species that it would not be possible for the author to arrive at a speedy determination of their 
species and characters, since their European congeners have been so imperfectly sketched out. That, for
