 These shales divide the Lower Lias marls with Ammonites mar- 

 f/ariiatus, or Middle Lias, from the Upper Lias marls with Am. radians. 

 They are constant in the minutest details over more than 60 miles, one 

 shaly band, less than a centimetre in thickness, covered with Posi- 

 donomya Bronnii, being everywhere noticeable. The author finds the 

 following zones constant (in descending order) : — Shale with Bel. tri- 

 partiius and Inoceramus. Shale with Limestone and Am. serpentinus 

 and Bel. gracilis. Limestone with fish. Band with Posidonomya 

 Bronnii. Passage-bed with Monotis suhstriata. G. A. L.
