314 WALCOTT 



Just southwest of the landing platform at Manuels Station green 

 shales occur in a hollow on the upper surface of a bed of erup- 

 tive rock that appears to have been injected along the contact of 

 the Cambrian and pre-Cambrian, and to have broken the succes- 

 sion of the strata. Both the conglomerate and portions of the 

 shales appear to be locally cut out by faults. Blocks of pinkish- 

 colored limestone are bedded in the eruptive rock, that were evi- 

 dently broken off near by, as layers of a limestone occur within a 

 short distance, farther along the track. In the green shales men- 

 tioned immense numbers of fragments of a large trilobite occur, 

 which Mr. Matthew has named Metadoxides manuelensis } To 

 the northwest of this outcrop, in a field across the railway track 

 and road, green shales of the higher horizon occur, in which 

 fragments of Olenellus {U.) hroggeri were found. A little dis- 

 tance beyond the hand-car house earthy nodular limestones are 

 exposed. These limestones, when decomposed, afford very fine 

 specimens of a number of species of Lower Cambrian fossils. 

 Among those noted were : Obolclla atlantica, Soleno^leura P 

 bombifrons ? Microdisais helena, ParmofhoreUa rugosa, Ole- 

 nellus {H.) hroggeri. There were also in one of the layers im- 

 mense numbers of Hyolithes. In a layer capping this earthy 

 limestone band a large number of heads of Solenopletira ? 

 harveyi and S. P howleyi were found, along with an unusually 

 long species of Orthotheca. Below this band of limestone a 

 reddish-purple, argillaceous shale occurs, in which many frag- 

 ments of Olenellus {H.) broggeri and Agraulos P were found. 

 A short distance beyond this the basal conglomerate outcrops, 

 and resting directly on it a layer of pinkish limestone, corre- 

 sponding in its contained fauna with the Smith Point (Hyolithes) 

 limestone of the Smith Sound section. In this layer of lime- 

 stone the following species were found : Helenia bella, Hyo- 

 lithes inifar^ H. -princeps, H. quadricostatus^ H. similis, H. 

 terranovicus, Hyolithellus 7nicans, Coleoloides tyficalis. 



The reddish-purple shale occurs again in a cutting about one 

 and one-half miles southwest of Manuels Station, where entire 

 specimens of Olenellus {H.) broggeri and AgraulosP were found. 

 At a point one-half mile beyond this, beside the railroad track,
