216 THE CANADIAN NATURALIST. [May 



stone appears to be quite unproductive of fossils, except in one or 

 two thin bands, which are closely packed full of minute gasteropods, 

 and the joints of slender stemmed crinoids. Associated with these 

 are occasionally found a fossil resembling a large Dentalium, but 

 Mr. Meek writes me that it does not belong to that genus. * The 

 fossils which characterize this bed seem to me to be quite distinct 

 from those found in the other beds. I have not observed this 

 limestone elsewhere. 



A bed of the red, marly sandstone overlies the limestone, 

 appearing also at the foot of the beach, and this is overlaid 

 in turn by a bed of limestone, fifteen feet in thickness, having 

 a southward dip of 45 ° . This last bed is seen to be over- 

 laid by a bed of the red marly sandstone, having a layer of 

 a green tint about a foot thick at its base. The face of the cliff 

 is here not very clear, but the limestone is seen to be broken 

 abruptly off by a fault, and the marly sandstone to occupy the 

 face of the bluff from top to bottom. This fault I developed by 

 cutting away the face of the bluff. 



The limestone last described is very compact, and of a light, 

 clear, leaden blue color, weathering, however, to a brown. It 

 seems to be made up of alternate layers of a very hard and con- 

 cretionary limestone, and of a softer kind, so that they wear 

 unequally, which gives to their upturned edges, exposed on the 

 sea shore, a rubbly appearance. This bed has usually been 

 supposed to be non-fossiliferous, and it is not mentioned by Dr. 

 Dawson in Acadian Geology. Struck with the resemblance the 

 highly tinted limestone bore to that which at Kennetcook affords 

 the Pliillipsia Howl of Billings, I was led to examine it with care, 

 and was rewarded by finding a specimen of that trilobite, together 

 with a Zaphrentis, common in the Kennetcook and Cockmegun 

 limestones, and a number of other fossils. Among these was a 

 Spirifer over two inches long, a valve of what Mr. Meek refers 

 doubtfully to Athyris lamellosa L'Eveille, a Productus quite 

 undistinguishable from the ordinary form of P. semi-reticulatus 

 and another species like P. costatus, with very long spines. 

 There are also several species of Myoid Lamellibranchs, and occa- 

 sionally one finds a minute fish tooth. An Athyris, somewhat 

 like A. subtilita, but distinct, occurs in this bed, both at Windsor 

 and Kennetcook, together with a Stenopora and a Fenestella 



* It is apparently a Serpulites. — J. W. D.
