radiating from a central point, but so imperfect and distorted that it can- 

 not be determined whether it is a compound species or a number of indivi- 

 duals of one of the simple forms accidentally congregated together. 



Cow Head. — In the black slates of Division P, the following were col- 

 lected, all of which occur at Point Levis, and are described by Prof. Hall : 

 Phijllograptus typus, Cr. hryonoides, Gr. denticulatus, Gr.fruticosus, Cr. 

 Headi, Calloc/raptus elegans and Ptilograptus jjlumosus. 



Bay St. Paul. — From the black slates of this locality, belonging to 

 Division P., we have G. hryonoides, Gr. denticulatus, Gr.fruticosus, Pti- 

 loyraptus plumosiis and C. elegans. 



PiSTOLET Bay. — The graptolites collected here are very imperfectly 

 preserved. The most common is a slender filiform species like (r. facci- 

 dus, but straighter ; a species closely allied to, if not identical with Gr. 

 eiliatus (Emmons) and a smo.ll Phyllograptus about three lines in length. 

 The slates and black dolomite of this locality, in which these species 

 occur, are undoubtedly of the same age as the black slates of the upper 

 part of Division N at Table Head. 



Other Fossils. 



3IurcTiisonia Anna, Pleurotomaria Laure7itiana, and P. caleifera occur 

 in Division Gr, at Port au Choix. At Cow Head in Division P, a trilo- 

 bite was collected, only distinguishable from Bathyurus conicus by having 

 the glabella smooth instead of tuberculated. Asaphus Pelops (^ante, 

 p. 317) also occurs at Cow Head. Lingida acuminata occurs in D, at 

 Bay Ste. Barbe. 



ObOLUS ? MURRAYI. (N. Sp.) 



Description. — The specimen is very nearly circular, broad ovate, width 

 a little greater than the length, uniformly and moderately convex ; the 

 shell black and corneous and covered with fine concentric striae. Length 

 7 lines ; width about 8 lines. 



Of this species only a single valve was found in a loose piece of grey 

 argillaceous limestone by Mr. Murray at Maiden Arm, Hare Bay, on the 

 east side of the northern point of Newfoundland. It belongs probably to 

 the Quebec group. 



Dedicated to Alex. Murray, Esq., who discovered it. 



Bathyurus solitarius. (N. sp.) 



Description. — Pygidium semicircular, length a little less than half the 

 width, uniformly romidcd behind, gently convex ; the side lobes smooth
