crush zone of finely broken and mended limestone facing the compact 

 blue limestone in which the break has occurred. Against the sheared and 

 polished surface of this crushed mass lie the crumpled edges of the sand- 

 stones. At the eastern end is a down thrown mass of limestone with the 

 sandstones above and behind it. This infallen remnant 

 of the sandstone shows its presence further back on the 

 mountain slope by a low depression whose sides converge 

 upward into a triangle. The rocks are the gray green 

 plant-bearing beds of the series, in some part filled with 

 shale pebbles and all the strata tilted into an abnormal dip. 

 This is the only infaulted remnant of the former sand- 

 stone mantle known to me on this peninsula but the fre- 

 quent occurrence of sandstone blocks and pebbles over the 

 mountain slopes indicates that the limestones have not 

 been clean swept of the debris of this ancient cover. 



CRINOID FROM THE GRANDE GREVE LIMESTONE 



In all the census of the early Devonic faunas described 

 in these volumes no Crinoidea have appeared. Their 

 absence from the arenaceous beds is perhaps less surpris- 

 ing than the dearth of their remains in the heavy series 

 of Grande Greve limestones. The occurrence here pre- 

 )ia K rammatic sketch of the sen ted is -thus not only of rather exceptional interest as 



south sea face of the For- 



iiion, indicating the on- j-^g so ] e evidence of the crinoid species but is specially 



gin of the little fishing 



beaches by differential noteworthy for the parasitic combination of an enormous 



sea erosion on the lime- 



stone Mocks slightly gastropod with this calyx. This specime'n was observed 



tilted along joint planes * 



transverse to the penin- by me exposed on the wave-worn surface of a steeply 



. sula and to the strike of 



the strata dipping and very compact layer of the Grande Greve 



limestones, lying beneath low water on the shores of Indian Cove, Gaspe". 

 The calyx only, and that largely denuded of its calcareous substance, was 

 exposed together with a considerable extent of stem. It was a matter of 

 arduous and dampening gymnastics to extract the specimen. The gastro- 

 pod appeared only after the specimen was detached from the layer. By
