ON THE FOSSIL PHYLLOPODA OF THE PALOZOIC ROCKS. 335 
yemains of one of the corresponding “ foot-gills,” on the other side, bent 
back upon itself, and thus thrust out of place. The free ends of these 
foot-gills are attenuated to more or less rounded points. They do not 
show any evidence of having possessed a marginal fringe. The discovery 
of these branchial locomotive appendages tends to ally Ceratiocaris still 
further with the genus Nebalia. See ‘“ Geol. Mag.” vol. ix. p. 564. 
Toc.: No. 292 (Linburn or Linn Burn, about two miles N. of Muirkirk, 
Lanarkshire). In thin-bedded shale (Upper Ludlow). Collected by A. 
Macconochie.’ Mr. R. Etheridge, jun., again alludes to this interesting 
subject in the ‘ Annals and Mag. Nat. Hist.’ ser. 4, vol. xiv. 1874, p. 9.
