5 Bairdia submucronata Jones and Kirkby.

= B. mucronata Reuss, var. submucronata Jones and Kirkby. 

 Trans. Geol. Soc. Glasgow, 1867. 



This beautiful little species is very rare in these shales, for I have 

 only found two specimens after the most careful scrutiny. 



6 Bairdia subelongata Jones and Kirkby. 



Jones and Kirkby : Quart. Jour. Geo. Soc. (loc. cit.), pi. xxx., figs. i-io. 

 Vine : Garb. Entom. Yorks. (op. cit., p. 231). 



Some few specimens found in the shales, may, I think, be referred 

 to this species. Like the Yorkshire forms, they more closely resemble 

 figs. I and 10 of the above-named plates than other figs, given by 

 the authors. 



In all probability Bairdia ampla Reuss, and B. amputata Kirkby 

 will have to be added to the above list, but the specimens are not 

 sufficiently worked as yet to allow complete identification. 



Fam. II. CYTHERID^. 



7 Cythere? sp. 



I have two or three forms that may be placed here, but I am some- 

 what doubtful about them. 



8 ? Cythere intermedia Munster. 



Jones and Kirkby : Palaeozoic Bivalved Entomos. Munster's sp. Ann. Mag. 

 Nat. Hist, May 1865. 



Rather rare in this locality. 



9 Darwinella? Berniciana Jones. 



Proceed . Berwicksh. Nat. Glub, Vol. x.. No. 2., p. 325, pi. ii., figs. 4« dfi a^c. 

 I have in my collection a few specimens of a very small Cytheroid 

 which closely resembles the figures of the one named above. But 

 though in shape the specimens may be referred to this species, I 

 am rather doubtful about placing them here, because the genus 

 Darwinella is an estuarine one, and if, as the author says, the 

 Carboniferous species is associated in habitat with Carbonia, it 

 probably is an estuarine form also. The other Entomostraca 

 described as occurring in the Redesdale shales are probably deep 

 water forms. However, with this notification I leave the specimens 

 here, temporarily, at least.
