Enumerates, figures, and in some instances describes various species, 



of which the following are new : — Modiolopsis Lelesconti and Aviculo-

pebbles have been derived from Brittany and Normandy. H. A. N.

Etheeidge, Eobeet, jun. On the Eelationship subsisting between 

 the Echinothuridce, "VVyville-Thomson, and the Perischoechinidce, 

 McCoy. Quart, Journ. Geol. Soc. vol. xxx. pp. 307-315, pi. xxiv. 



After a consideration of the characters of the existing genera Cal- 

 veria and Phormosoma, the author discusses the peculiarities of the 

 Cretaceous genus Ediinothuria. The Palaeozoic genera Airhceocidaris, 

 PalcecMnus, Perischodomus, LepidecJiinus, Eocidaris, Melonites^ and 

 Oligoporus aie next considered. The author concludes that the Pms- 

 choecJiinidce constitute a distinct family, though related in some respects 

 to the Echinoihuridce. This relationship is especially seen in the 

 imbrication and overlapping of the plates of the ambulacral and inter- 

 ambulacral areas which occurs in the Palaeozoic genera LepidecMnus 

 and Lepidestlies. H. A. N.
