 Describes a well-preserved large insect, the two best-preserved wings 

 being 2^ inches in length, and 1 inch and 1| inch respectively in 

 width. It shows the " shrill-vein " so characteristic of many of the 

 Orthoptera, and presents a strong likeness to Gorydalis (Gri/llacris) 

 Bronr/niarti, from the Coal Measures of Coalbrook Dale. Prom the 

 dilatation of the prothorax it is placed in the neighbourhood of the 

 Mantidae. It is named Lithomantis carhonarius, and compared with 

 the living Blepharis domina, from the White Nile. A list of Palaeozoic 

 Insecta, Myriapoda, and Arachnida is appended. H. A. N.

 with overlapping plates. Proc. Nat. Hist. Soc. Glasg. vol. ii. pt. ii. 

 pp. 225-231. 

 Shows that the arabulacral plates of Archa^ocidaris were imbricated, 

 and that certain of the interambulacral plates were furnished with 

 bevelled edges in such a manner as to communicate some flexibility to 

 the entire test. The provisional name of A. Scotica is proposed for . 

 certain teeth which differ materially from those of A. Urii. The speci- 

 mens described are from the L. Carboniferous of Campsie. H. A. N.

The question as to whether these are truly Polyzoa is reserved for 

 future discussion. The species described as new are G. margincdis, G. 

 elegans, G. aspera, G. Jlexicarinata^ G. retrojle.va, and G. laxa. The 

 subgenus Diplopora is proposed for G. marginalise on account of its 

 possessing a minute aperture below the true cell-mouth ; and the name 

 Acanthopora is proposed as a subgeneric designation for the previously 

 described G. stellipora, from its possession of 8 radial spines guarding 

 the cell-mouth. H. A. N.

Describes a number of Radiolarians from the Chalk of Germany 



belonging to the genera Dictgomitra, Dictgocha, Cenosphceraj and 



Stglodicfga. The genus Dictyomitra is founded and defined for part of 



the forms referred by Ehrenberg to Eucyrtidimn, 6 new species are 



described (see Index of Species). H. A. N.
