Athyris subtilita, Retzia radians Morr., Spirifer lineatus, S. Urii Flem., Productus longi- 

 spinus Sow., P. scabriculus Sow., P.costatus Sow., Fusulina cylindrica, and F. robusta. 

 The following figures represent some of the remains of Articulates: (a.) Crustaceans, 

 — No species of Trilobites are reported from the foreign Coal-measures, —showing' 

 apparently, the complete extinction of this ancient tribe. Fig. 683, Prestwickia ro- 



Fiars. 682-686. 



Fig. 682, Gampsonyx fimbriates ; 683, Prestwichia rotundata (XX); 684, Cyclophthalmus senior; 

 685, Dictyoneura anthracophila ; 686, Blattina primaeva.

Anthrapalaemon Salteri. 



tundata Woodw., reduced one half, Coalbrook Dale; P. anthrax 

 Woodw., Coalbrook Dale; Belinurus trilobitoides Woodw., Ireland 

 and Coalbrook Dale; B. regince Baily, Ireland; B. arcuatus Baily, 

 Ireland. Fig. 682, Gampsonyx (Euronectes) jimbriatus Jordan, a 

 Schizopod. Fig. 686 A, Anthrapalcemon Salteri, from Lanarkshire, 

 Scotland. A. dubius S. and A. Grossarti S. are other species re- 

 ferred to this genus, the former from Coalbrook Dale (includes the Glyphea (f) dubia S., 

 and Apus diibius M.-Edw.), and the latter from Lanarkshire; but the broad flattened 

 carapax indicates a nearer relation to JEglea and Galathea than to Pakemon. Pygoceph- 

 alus Couperi Hux. is the name of a Schizopod from near Manchester, England. 



(b.) Myriapods. — Euphoberia Brownii Woodw., from Glasgow, E. anthrax Woodw., 

 from Coalbrook Dale, Xylobius sigillarim Dn., from Glasgow and Huddersfield.
