﻿Notes on Fossils from Prince Charles Foreland. 163 



More complete specimens are necessary before this form 

 can be classified and its affinities ascertained ; in its present 

 state it cannot very well be figured, but the above descrip- 

 tion may give some idea of its nature. 



?Eamipoiia., Toula. 



The cast of a large pinnate Bryozoon is provisionally 

 referred to this genus/ but as it is in a very poor state of 

 preservation, it must be left for the present unclassified. 



Remarks. — The Bryozoa described above appear to be the 

 only ones present in the fragments of limestone under 

 investigation. Two of these, i.e.^ Fenestella cf. retiformis 

 and Folypora, are actually rock-building organisms, and con- 

 tributed to the building of this particular rock just as corals 

 do in coral reefs. This exuberant growth of Bryozoa is 

 similar to what obtains in various parts of the world, as for 

 instance in the Permian rocks of South Yorkshire and 

 Germany. It is interesting to note this similarity of condi- 

 tions in countries so far apart. 



BRACHIOPODA. 

 Productidae. 



Prodiictus horridus, Sowerby. 



This well-known fossil is represented by one or two almost 

 perfect specimens, some of which have preserved their 

 beautiful silvery mother-of-pearl-like test. Although none 

 I was found with the spines still attached, many of the latter 



occur scattered through the matrix. 

 ' The present specimens differ in no way from the typical 

 forms of Productus horridus from the Permian beds of 

 Europe, so that a description is uncalled for. On the other 

 hand, its occurrence in the Bryozoa Limestone is very im- 

 j portant, as it fixes the age of the latter as Permian. 



An interesting comparative study of Productus horridus 

 and its mutations in Spitsbergen will be found in Professor 

 Freeh's Dyas, pp. 497, 498.2
