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

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

 the limits of the /(5e<r-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 //^fti'-beds were found by him at Munger, near Uadstock, associated 

 with the Ja?)iesoni-heds ; and that near the top of an old quarry, formerly worked for 

 road-material, he collected Aegoceras Maugenesti, Aegoceras Valdani, Aegoceras striatum, 

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

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

 not easily extracted. Belemnites paxillosus and _5. apicicurvatiis, LittorincB and other 

 minute Gastropods were found in fine preservation with Crgptania exjpansa. Among 

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

 and of Brachiopods, Rhgnchonella rimosa and Bhgn. furcillata. We have here a very 

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

 fossils therein.
