In addition to the above, Prof. Jones describes another species : 

 Darwinella ? Berniciana Jones, a ' little Cytheroid which occurs in 

 great numbers, and in good preservation (valves united), with the 

 Bernix Tafez Jones, found by Prof. Lebour' (op. cit.,pp. 319, 325). 



In 1879 Prof. T. Rupert Jones and J. W. Kirkby published 

 their joint paper on 'Species of the Ostracodous Genus Bairdia 

 M'Coy' (Quart. Jour. Geol. Soc, November), and in it the authors 

 name many localities for Carboniferous species ; and as this paper is 

 well illustrated, the student will do well to study this peculiar group 

 with the assistance afforded by it. 



My own paper on the Yorkshire Garb. Entomostraca (Geol. and 

 Polytec. Soc. Trans., 1884, pp. 226-238), may be referred to for 

 special details, and for comparing the Northumberland with the 

 Yorkshire species. 



Fam. I. CYPRIDM. 



1 Bairdia Hisingeri Munster. 



J. and K., Quart. Jour. Geol. Soc, Nov. 1879, pi. xxix., fig. 4-10, and pi. xxx., 

 fig. 12. 



See also Ann. Mag. Nat. Hist., J. and K., 1865. 

 Carb. Entomos. Yorks., Vine (op. cit., p. 232). ♦ 

 This species varies very much in the Redesdale Shales, and some 

 of the specimens are fine and plump. 



2 Bairdia Hisingeri Munster, elongate var., Jones and Kirkby 

 (op. cit.) pi. XXX., fig. 12. 



Some of the specimens of this variety are finer, and of greater 

 length than many of the elongate forms from other locaUties in 

 British Carb. rocks ; but, like B. Hisingeri, specimens vary much.
