C — From Matanne, River St. Lawrence, Quebec, ("Upper 

 Gambrian"). 



15. Bryograptus multiramosus, 



Besides these fifteen new species of Rhabdophora and 

 Cladophora, there are four more new species described, viz : 

 two species of Nicholson's genus Dawsonia and two species of 

 Crustacea, referable to the genus Caryocaris. There four are 

 all from Point Levis, Quebec. 



D — From Levis, Quebec, (in shales of the Levis formation). 



16. Dawsonia monodon, 



17. Dawsonia tridens, 

 Crustacea. 



18. Caryocaris oblongus, 

 rg. Caryocaris curvilatus. 



With the exception of the last two above mentioned species, 

 the new forms described by Dr, R. R. Gurley are well represented 

 in the collections made by James Richardson, T. C. Weston, 

 R. W. Ells, W. E. Decks, Sir William Dawson, A. P. Low, N.J. 

 Giroux and the writer for the Geological Survey of Canada,Ottawa 

 and for the- Peter Redparth Museum of McGill College, Montreal. 



Our Canadian graptolites certainly need revision and it is 

 earnestly hoped that before long some one will be allowed to 

 undertake the task of bringing our knowledge of this most 

 important group of palaeozoic fossils and its classification 

 up-to-date. 



There are few classes of fossils in the Palaeozoic sequence 

 of strata which afford better evidence of the exact age to which 

 to refer the formations from which they are derived than grap- 

 tolites, and their study is of more than ordinary value for the pro- 

 per understanding of the true relations of the older and greath' dis- 

 turbed and at the same time very fossiliferous strata of the Lower 

 St. Lawrence, in that series of strata better known as the "Quebec 

 Group" of Logan and Billings, a series quite natural in its develop- 

 ment and wide in its distribution. Furthermore, this Quebec series 

 abounds with the remains of . graptolites and the new species 

 described by Dr. Gurley are evidence of the amount of new
