58 G. F. MATTHEW ON THE 



? Ctenopyge pecten. Sait. 



Certain layers iu the limestone lentils abound with slender detached spines that may 

 belong to this species, and on one of them was found a fragment of a rachis which appar- 

 ently was a part of the pseudo-pygidium of this species ; it has several joints, and the 

 side is obliquely furrowed with several short furrows, like that part of this species. 



CONOOEPHALITES, Adams. 

 CONOCEPHALITES (?) CONTIGTJUS, n. sp. (PI. XIII, figs. 1-1 a and b.) 



Occurring sparingly among the species found in the limestone nodules of the black 

 shales, there are a few heads of a small species of Conocephalites. The test was very thin 

 and flexible and no perfect head has been recovered. 



Middle-piece of the head arched downward in front ; marginal fold straight and nar- 

 row and in contact with the front of the glabella. Glabella narrowly conical, truncate iu 

 front, impressed by three pairs of furrows, the posterior pair directed backward and con- 

 nected on the axis of the glabella, the two anterior pairs short. Fixed cheek wide in front, 

 traversed oblic^uely by a distinct ocular fillet. Occipital ring separated from the glabella by 

 a strong furrow and bearing a median tubercle. Ocular lobe opposite the posterior two- 

 thirds of the glabella and about half its width from it. Posterior marginal fold narrow. 



Sculpture. — Surface smooth. 



Size. — Middle-piece of the head, length, 4 mm. ; width in front of the eyes, 6 mm. 



Horizon and Locality. — From the black shales of Division 3 a Germaine street and 3 b 

 King-street, St. John. 



Of this species only a few heads have been found. Sphœrophlhalmus majusculus of the 

 Swedish Peltura beds resembles this species, bu.t has only one light furrow on the gla- 

 bella. It also is somewhat like C. Wirthi of the fauna of Hof, in BaA^aria, but in that 

 species the glabella and marginal fold are separated by an area. The nearest species 

 appears to be C. quadrans (or quadriceps), Dames, of the fauna of Liau Tung, China. 



(B) SPECIES FROM LOWER HORIZONS. 



On reexamining the outcrops on Kennebecasis River, and studying some fresh mate- 

 rial from there, it is found that the fossils of Long Island, in that river, should probably 

 have a lower position in the Cambrian beds as.signed to them. Both in this basin and iu 

 that of the Long Reach the sedimentation has been different from that of the St. John 

 Basin, especially in the Johannian Division {T)\y. 2). In these interior basins this division 

 is much thinner, and shales take the place of flags to a considerable extent. Two fossils 

 from the Long Island beds were described in ' The Canadian Journal of Science.' These 

 are here more fully described, and some other species added. 



LINGULELLA, Salter. 

 LiNGULELLà Starri var. MINOR. (PI. XII, figs. 5 a and b.) 

 This neat little species is referred to Lingulella Starri on account of the sculpture.
