 which is rare in the Devonian. 



t A species with a sharply carinate nodose dorsum, each node being 

 produced inio a stout spine. This is altogether a novel style of orna- 

 ment among the Bellerophontids. It is interesting to observe that near 

 the aperture where some of the species are broken off, it is very evi- 

 dent that the latter were extensions of the outer shell -layer only, and did 

 not open on the inner surface of the shell. 



Cyrtonella hor- 

 rida, sp. nov. 



Some fossil Crustacea of considerable interest, and new to our 

 collections, have been received. Prof. J. F. Whiteaves of the 

 G-eological Survey of Canada, has sent specimens of his recently- 

 described Phyllopod (?) Anomalocaris Canadensis, from the 

 Cambrian fauna of Mt. Stephen, British Columbia. From the 

 Peabody Museum, Yale University, through Prof. C. E. Beecher, 

 we have obtained an interesting series of the Cambrian trilobite, 

 PtycJiOj)aria Kingi, numbering about sixty specimens. By pur- 

 chase the museum secured from Mr. L. G. Kexford, a remarkably
