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

 Upper Silurian system:" part ii, " Stromatoporida3 of the Upper Silu- 

 rian system;" part iii, fifteen new species of ^N'iagara fossils. Part one 

 contains the descriptions of twenty-one new species : Phyllofjraptus f 

 dubius, Dendrograptus raynosus, D. Simplex^ J). Dawsoni, D.frondosus, 

 D. praegraciUs, D. spinosus, Callograptus granti, Q. multicaulu, G. mi- 

 niitm, Dictydneura expansum, Galyptograptus micronematodes, G.f radi- 

 aius, Acanthograptus pulclier, TnocauUs icalkeri, J. diffusus, t. eervi- 

 cornis, t. phycoides, t. ramulosus, Thamnograpius ? multiformis, Cyclo- 

 graptus rotadentahis, and of one new genus Cyclograptus ; besides there 

 are descriptions and illustrations of nine species previously described by 

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

 new species are described: Cannopora tcalkeri, C. mirabilis, Gcetiostoma 

 ristigoncJiense, Gcenostoma botryoideum, Dictyostoma reticulaium. Part iii 

 contains the following new species : Palceaster granti, EMnopora venosa, 

 Glatliropora ? gracilis, Fenestella bicornis, Polypora {Feriestella ?) albion- 

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

 formis, Gonularia rugosa, G. icilldnsi, OrtJwceras bartonense, Gyrtoceras 

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

 trations are so poor that it will be very dif&cult, if not impossible, for 

 future workers to recognize Mr. Spencer's types.
