Spencer, J. W. — Niagara Fossils. (Bull. Miis. Uni. State of Missouri, 

 pp. 1-61, pis. i-ix. Saint Louis, 1884.) Published also in Saint 

 Louis Acad. Sci., vol. iv, No. 4. 



This work is divided into three parts : Part i, " Graptolitidte of the 

 Upper Silurian s^'stem;" part ii, " Stromatoporidse of the Upper Silu- 

 rian system;" part iii, fifteen new species of Niagara fossils. Part one 

 contains the descriptions of twenty-one new species: Phyllograptus ? 

 diibius, Dendrograptus ramosiis, D. Simplex, J). Daicsoni, I), frondosus, 

 D. p^raegracilis, D. spinosus, Callograptus granti, G. multieaulifi, G. mi- 

 nutm, Dictyoneura expansum, Galyptograptus micronematodes, G. ? radi- 

 ains, Acantliograptus pulcher, Tnocaulis ivalkeri, 1. diffusus, I. cervi- 

 cornis, t. phycoides, t. ramulosus, Thamnograptus f multiformis, Gyclo- 

 graptus rotadentatus, and of one new genus Gyclograptus ; besides there 

 are descriptions and illustrations of nine species previously described by 

 the author in the Canadian Naturalist, 1878. In part ii the following 

 new species are described : Gannopora tcalJceri, G. mirabilis, Goenostoma 

 ristigonchense, Goenostoma botryoideum, Dictyostoma reticulaium. Part iii 

 contains the following new species : Palwaster granti, Rhinopora venosa, 

 Glatliropora f gracilis, Fenestella bicornis, Polypora {Fenestella f) albion- 

 ensis, Lingula ingens, Discma clara, Grania anna, Pleurotomaria clipei- 

 formis, Gomdaria rtigosa, G. wilkinsi, OrtJioceras bartonense, Gyrtoceras 

 reversum, Lituites niagarensis. It is much to be regretted that the illus- 

 trations are so poor that it will be very difficult, if not impossible, for 

 future workers to recognize Mr. Spencer's types.
