36 Messrs. Jones and Kirkby on Carboniferous Entomostraca. 
Staffordshire, in shale (J. Ward) ; in ironstone from the Coal- 
measures near Dudley (Geol. Survey) ; from Chesterfield in 
ironstone (Binney) ; from Babbington, Notts, in shale; from 
Shaley Brow, Rainford (Binney) ; from Glodwick, near Oldham 
(Binney) ; from Agecroft Colliery, near Manchester (Binney) ; 
from Ashby-de-la-Zouch (A. H. Green) ; from Hagley Shore, 
Lancashire, and from Holcombe, Bradshaw, Cranbourke, and 
Brow Peel in the same county ; from Granton (Harkness) ; from 
Carluke (Rankine) ; and from the shales associated with the 
Shotts Gas- and Furnace-Coals, Lanarkshire (Grossart). 
In the ‘ Memoirs of the Geological Survey,’ illustrative of the 
several sheets of the Geological Survey Map, are several refer- 
ences to the occurrence of Bivalve Entomostraca in the Coal- 
measures. Beyrichia arcuata is quoted as occurring in shales of 
the Middle and Lower Coal-measures of Lancashire and of the 
“* Holeombe-Brook Series ” (referred to the “ Millstone-grit ” by 
the Surveyors) in the same district : Mem. Geol. Surv., “ Geology 
of the Country around Bolton-le-Moors,” by Mr. K. Hull, 1862, 
pages 33, 34, 40, &c. B. arcuata is also mentioned as belonging 
to the Middle Coal-measures, near Wigan, in the ‘ Geology of 
the Country near Wigan,’ 2nd edit. 1862, Appendix *, by Mr. 
Salter, pp. 386 and 38, and is figured in a woodcut at p. 37 
(fig*.2515)'. 
1836. Phillips and Williamson.—In 1836 Professor J. Phillips 
(Brit. Assoc. Report, 1841, Sections, p. 64) and Professor W. 
C. Williamson (Phil. Mag. new series, vol. ix. p. 351) dis- 
covered numerous small Entomostraca in the Upper Coal-mea- 
sures at Ardwick, near Manchester (see ‘ Monograph Foss. 
Estheriz,’ Pal. Soc. p. 118). Excepting a few specimens of 
Leaia, these Entomostraca were referred to as Cyprides, and 
are possibly the same as Cypris inflata of Murchison, which is 
found in the uppermost Coal-measures of Shropshire. 
1839. Murchison and Sowerby.—in 1839 Sir Roderick Mur- 
chison and Mr. J. de C. Sowerby described and figured a small 
Bivalve Entomostracan (obtained by the former from the Upper 
Coal-measures of Shropshire) as Cypris inflata, in the ‘ Silurian 
System,’ p. 84, woodcuts figs. A 1, A2, A3, which figures were 
repeated im ‘Siluria, Ist and 2nd editions (2nd edit. 1859, 
p. 322, fig. 83), and have been copied in other works on geo- 
logy. These illustrations are really those of a small gibbous 
Leperditia,—with a straight back, strong dorsal angles, and con- 
vex ventral margin. In the ‘Silurian System, p. 84, it is 
* In this Appendix, p. 37, fig. 2, 4, is figured another Beyrichia (under 
the name of ‘‘ B. Binneyana, Jones’’), which is B. subarcuata, Jones, Pal. 
Soe. 1862, Monogr. Foss. Esth. p. 120, pl. 5. fig. 16. The name “ B. 
Binneyana’”’ was intended for a different form as yet unpublished.
