Correspondence — Mr. Edwin Witchell. 47 



Cephalopoda-bed have been included by the late Dr. Wright and 

 others in their published works in the term " Pea Grit," and he 

 refers me to the paper by Dr. Wright on the so-called sands of the 

 Inferior Oolite " as showing that I am in error. I have referred to 

 the paper cited, and find that in the section (Fig. 1) only one bed is 

 shown as including the Pea Grit and the underlying beds, although 

 in the explanation at foot it is called " Pea Grit and ferruginous 

 oolite," and marked ABC; but the description in the following 

 page is headed "Pea Grit (Inferior Oolite)," and under this heading 

 the beds A B and C are described : the description of A and B 

 appears, however, to be substantially the same. 



In Dr. Wright's latest work " Monograph on the Lias Ammonites" 

 the section of Leckhampton Hill is repeated (fig. 11, page 151) ; and 

 on reference to the description (p. 152), I find the heading is 

 "Pea Grit (Zone of Sarpoceras Mnrchisonice, Inferior Oolite)," the 

 subdivision being the same as before, and the description being 

 wholly under this heading. 



I think the meaning is clear, namely, that it was intended that the 

 term " Pea Grit " should apply to all the beds, although, for the 

 purpose of giving a more accurate description, a subdivision of them 

 was convenient. 



Mr. Wethered refers me to Dr. Wright's section of Cleeve Hill, 

 but the extract is incorrectly given, doubtless an error in printing. 

 For— 



Pea Grit 21ft. 30 in. 



Coarse ferruginous ooKte 22ft. 5 in. 



Read — 



Peat Grit, No. 21 30ft. Oin. 



Coarse ferruginous oolite 5ft. Oin. 



The correct reading confirms my statement, except as regards the 

 lower 5ft. 



The section of Cleeve Hill is also repeated in the monograph on 

 the Lias Ammonites (fig. 12, p. 155), and in the description (p. 161) 

 the beds are called " Pea Grit," and the three subdivisions are 

 described in much the same language as is used in the description 

 of the beds at Leckhampton. Edwin Witchell. 



COEEECTION OF MIOCENE INSECTIVORA. 



Sir, — With your permission I will avail myself of the Geological 

 Magazine to correct an error into which I have been led by the 

 writings of others in part i. of the " Catalogue of Fossil Mammalia 

 in the British Museum" (1875). 



On page 19 of that volume I followed Dr. 0. Fraas ' in identifying 

 the Auvergne PJesiosorex soricinoides {Erilcaceus soricinoides, of 

 Blainville) with Parasorex socialis, Meyer, of Steinheim. Having 

 recently, however, had cause to consider further the affinities of the 

 Miocene Insectivora, I have been led from an examination of the 

 figures given by Fraas and De Blainville to the conclusion that 

 the identifications made by the former writer are totally erroneous. 

 The Steinheim Parasorex socialis is, as Fraas states, closely allied to 

 1 " Fauna von Steinheim," p. 4 (1870).
