268 REPORT ON THE STATE CABINET. 



1861. Prof. M'CoY sent to the writer a proof of a plate of grapto- 

 lites from the " Palceontology of Victoria^ Among the figures are spe- 

 cies closely resembling or identical with G. ramosus, G.furcatus, and G. 

 gracilis; while others resemble G.])ristis^ G. Sagittarius^ &c. The descrip- 

 tions or farther illustrations have not come under our notice. 



1861. E. Billings " On the Occurrence of Graptolites in the Base of the 

 Lotver Silurian." The paper contained a review of the work of Fried- 

 rich Schmidt, and a comparison of the graptolitic zones in Europe and 

 America, with a view to show that the graptolite-schists of Norman's 

 Kill, near Albany, are not in the upper part of the Lower Silurian divi- 

 sion, or Hudson-river group {^Canadian Naturalist and Geologist^ Vol. vi, 

 pp. 344 and 348). 



1863. Sir William E. Logan recognized the occurrence of Graptolithus 

 bicornis, G. ramosus^ G. mucronatus, and G.pristis, characteristic species of 

 the shales of Norman's Kill, in the Utica and Hudson river formations of 

 Canada {Geology of Canada^ p. 200, and Catalogue of Fossils, p. 942 ; Idem, 

 Graptolites of the Quebec group, pp. 226 and 228). 



1863. J. W. Salter (Note on Skiddaw-slate Fossils) noticed some new 

 species of graptolites, proposing the new genus Tetragraptus, and 

 describing the genus Dichograptus previously proposed, as cited above, 

 including other characters {Quarterly Journal of the Geological Society , Vol. 

 xix, pp. 135-140, with illustrations). 



1866. Henry Alleyne Nicholson, " On some Fossils from the Graptolitic 

 Shales of Dumfriesshire." This paper announces the discovery of numer- 

 ous minute bodies in the graptolitic shales, and associated with the G. 

 sedgwicMi in such a manner as to sustain the belief that they are ovarian 

 vesicles, or graptolitic gonophores similar to those found in the shales of 

 Norman's Kill, near Albany {Proceedings of the British Association, Thirty- 

 sixth meeting, 1866, p. 63). 



1867. William Carruthers, " Graptolites; their Structure and Systematic 

 position" with illustrations {Intellectual Observer, Nos. Ixiv and Ixv). 



1868. William Carrdthers. A revision of the British Graptolites, 

 with descriptions of the new species and notes on their affinities {Geologi- 

 cal Magazine, Vol. v, Nos. 2 and 3, March, 1868. 



^*^ The Graptolithus from the Hoosic slate-quarries was named by 

 Prof. Eaton Fucoides secalinus, and the specimens were thus labeled in 

 the Cabinet of the Rensselaer School at Troy, as known to the writer 

 from 1832 to 1836 ; but we have been unable to find any published 

 descriptions.
