154 R. Etheridge — Notes on Fossils from Med Somalonotus Beds. 



part of this communication Dr. Callaway's description of this section, 

 and it contains no single word about faulting. Nor does his paper 

 (Q. J. G. S. vol. xxxvii. p. 220), in which he refers to the same 

 sections. It is much to be regretted that Dr. Callaway did not 

 publish the section in his private note-book, " which is almost a 

 facsimile " of mine, and which he admits to be a faithful representa- 

 tion of the facts, instead of the inaccurate and misleading sections 

 given in his paper just referred to. The case then stands as follows : 

 Black shales and a quartz conglomerate are shown in juxtaposition 

 in two quarries, near Nebo. Dr. Callaway has asserted that they 

 are unconformable, and has based upon that certain arguments. In 

 the northern or upper quarry he now admits that there is a fault, 

 while in the southern or lower quarry (Fig. 2) he has, according to 

 my interpretation, mistaken joints for bedding ; the base of the 

 crushed shales as a matter of fact coinciding in direction with the 

 bedding of the conglomerate. 



In concluding I may just observe that Professor Bonney no longer 

 holds the view which Dr. Callawa^'^ so strongly supports in the first 

 quoted paragraph, namel3% that the Twt Hill conglomerate is a part of 

 the granitoidite series. Does Dr. Callaway still adhere to this view ? 



The last point in Dr. Callaway's paper as to felsite pebbles I pass 

 over, inasmuch as I have dealt fully with that matter in my reply 

 to Prof. Bonney. 



In the foregoing I have not touched upon the metamorphic rocks 

 of Anglesey, to which a considerable part of Dr. Callaway's paper is 

 devoted. That is a subject in no way connected with the matters 

 treated of in this paper, and I leave it for another communication. 



III. — Notes on some Fossils from the Red Beds of the Lower 



Devonian, Torquay, South Devon. 



By Egbert Etheridge, F.E.S., F.G.S., etc. 



(PLATE IV. Figs. 4—11.) 



MR. A. CHAMPERNOWNE having requested me to examine 

 and briefly notice some fossils in his collection, obtained from 

 the Red Homalonotus Beds of the Lower Devonian, Torquay, I have 

 endeavoured to comply with his request so far as the condition of 

 the specimens permits. Besides the Homalonotus remains, there are 

 a number of Mollusca preserved as casts, but, for the most part, so 

 distorted by slaty cleavage, as to render their determination most 

 difficult. 



The following remarks on the probable affinities of the fossils 

 figured on Plate IV. may, it is hoped, induce other collectors to 

 examine the beds frow whence they were obtained, and so lead to 

 the discovery of more perfectly preserved specimens.

 There appear to be two genera of Bivalve Mollusca represented 

 here, namely, Cypricardia and Modiolopsis ; the former might be a
