VINE : MICRO-PALEONTOLOGY. 



or Yoredale Shales, of the Carboniferous series of Northumberland. 

 It may be that my material was too poor to yield a fairly represen- 

 tative series; if so, the local student is now in a position to add to the 

 above, if he sets to work in earnest, and no one will be better pleased 

 than myself to hear of the results. Mr. Howchin, however, when he 

 sent me the material, assured me that I had a fairly representative 

 series of shale-washings, so far as he was able to procure them. Since 

 his time many new localities may have been opened up, and I have 

 not the least doubt but that specimens from many of these new 

 localities may be in the cabinets of Professor Lebour and others, if 

 so, I should like to hear about them. It would give me great 

 pleasure to go over any Northumbrian series, large or small, for the 

 purpose of obtaining as full a list as possible. But with the exception 

 of receiving one letter from Professor Lebour at the beginning of my 

 present labours, no other interest seems to have been excited in the 

 publication of papers on the Palaeontology of the Northern Shales. 



ENTOMOSTEACA. 



(See Naturalist, pp. 97-101, 209-210.) 



The Ostracoda of the Upper Shales are in much better preser- 

 vation than the Polyzoa, and specimens seem to be fairly abundant. 

 Some of the Shale-washings, especially those from Ingoe, are full of 

 organisms, and the Entomostraca and Foraminifera are fairly 

 abundant. I had two siftings of the Ingoe Shales from Mr. Howchin, 

 but the most valuable for Foraminifera is the finest of these. 



Fam. I. CYPRID.^. 



1 Bairdia Hisingeri Munster, Var. elongata Jones and Kirkby 



(Naturalist, p. 98). 



I have not found the true B. Hisingeri in these Upper Shales, 

 and the elongate variety is very rare. 



Localities. — Yoredale : Fourstones, Ingoe, Northumberland ; 

 Hurst, Yorkshire. 



2 Bairdia subelongata Jones and Kirkby (Naturalist, p. 99). 

 This also is a rare species in the Upper Carboniferous Shales of 



Northumberland. I have only two examples. 



Localities. — Yoredale : Ingoe, Northumberland ; Hurst, York- 

 shire. 



3 Bairdia plebeia Reuss. (Naturalist, p. 99). 



Jones and Kirkby, Quart. Journ. Geol. Soc, November 1879, pK xxviii., figs. 

 9 to 19. (See fig. 13.) 



The specimens vary a little in these Upper Shales. One of the 

 Ingoe forms has surface ornamentation, as referred to by the authors
