The fossils of this zone in other localities are often catalogued with those from the 

 Jamesoni-heds,, on which they rest, and it is rare that we are able to define so distinctly 

 the limits of the J(5e^-beds as formerly we were able to do near Cheltenham. 



Mr. E. B. Tawney, F.G.S., has made a careful study of the Lias around Radstock, 

 and embodied his observations in an exhaustive memoir^ on this subject. From this 

 we learn that the 75e«-beds were found by him at Mimger, near Radstock, associated 

 with the Jamesoni-heds ; and that near the top of an old quarry, formerly worked for 

 road-material, he collected Aec/oceras Maugenesti, Aegoceras Valdani, Aegoceras striatum, 

 and Lytoceras fimbriatum. Aegoceras brevispina, Aegoceras Jamesoni, and Amaltheus 

 Ibex seem to occur throughout, and in the same locality Belemnites were abundant, but 

 not easily extracted. Belemnites jjaxillosus and B. apicicurvatus, Littorints and other 

 minute Gastropods were found in fine preservation with Crgptcenia expansa. Among 

 the bivalve shells Astarte sfriato-sulcata, Inoceramus ventricosus, Pholadomga ambigua ; 

 and of Brachiopods, Bhgnchonella rimosa and Bhyn. furcillata. We have here a very 

 good account of the Ibex-h&d?, of Munger, with the distribution of some of the leading 

 fossils therein.
