320 Lower-Carboniferous Untomostraca. By T. R. Jones. 



at Walwick Grange, below ChoUerford Bridge. " He adds that 

 the Brunton shale is the bed which was worked years ago on the 

 hillside below Brunton in connection with a black-band-ironstone. 

 This is on the same horizon as the shale at Walwick Grange ; but 

 the latter is the only available spot where it can now be seen, the 

 shale-heaps at Brunton having long ago been covered up with 

 grass. " 



[Prof. Lebour further tells me by letter that he has had the 

 old shale-heaps (where Mr Tate got his Bernix) at Brunton dug 

 up afresh, and that he has obtained numerous specimens of both 

 Bernix Tatei and Barwinella (?) Berniciana, with perhaps some 

 other species, from it*.] 



We may note also that the Geological Surveyors of Scotland 

 have collected from a soft brownish-grey shale of the Calcif erous- 

 Sandstone series (Tuedian), at Fulwood Burn, Lanarkshire, an 

 internal castf of an Ostracod somewhat similar to Bernix Tatei, 

 having a mid-dorsal impression, with some associated small 

 irregular depressions. It is rather larger, however, and the 

 profiles of the valve (edge and end) differ from those of the 

 foregoing.

PL II., fig. 3a, 3b. 



This kind of valve among fossils is usually referred to Cythere, 

 but it may be equivalent to the recent genus Macrocypris, as far 

 as the outline can show, — as the soft parts and limbs are 

 necessarily wanting, it is safer to keep it in Cythere, used in a 

 general and, to a great extent, an artificial, sense. 



In shape the valve has one edge (dorsal) much arched and 

 nearly semi-circular, bnt with the highest convexity at the post- 

 erior third ; the other edge is nearly straight (very slightly 

 incurved), length 1 millim. One end (anterior) is rather more 

 truly rounded than the other, which slopes down rapidly 

 fr(jm the highest dorsal curvature, where the height of the valve 

 is almost equal to half of the length. The profile of two valves 



*Prof. Lebour has just lately favoured me with specimens of this 

 Entomostracan shale. As he intimated, it contains other species, unde- 

 termined and well worthy of attentive study. One is a ^^yHcAi«, perhaps 

 B. multiloba. Some of the shale appears to have been almost wholly 

 composed of the Bernix and is a real oil-shale.
