608 MR, K. D. VERNON ON THE GEOLOGY AND [DcC. I912, 



We have seen that the rocks from which these fossils have been 

 obtained unconformably overlie, and are 5-ounger than, the Keele 

 Beds ; and it will be shown on a snbseqnent page that they are 

 themselves unconformably overlain by, and are older than, the 

 Trias. The sediments in question may thus have been formed 

 contemporaneously with the Permian of the Xorth of England, or 

 they may even be the English representatives of the Stephanian 

 (Carboniferous) Series of the Continent. 



The fossils in the foregoing list will now be considered, with the 

 object of fixing the age of the rocks. In this connexion the 

 animal footprints recorded above, as well as the ' bone of a fish ' 

 figured by Murchison & Strickland, are of little value, and may be 

 omitted. 



The fossil which Salter considered to be allied to Stroiolicdosia is a 

 badly-preserved cast in sandstone, the real nature of which appears 

 to be very doubtful. There is reason to believe that this specimen 

 is not a Permian fossil, but a derived shell (possibly of Siluriau age) 

 from the pebbles of the Corley Conglomerate, which is known to 

 occur at Exhall. 



Of more importance is the skull of Dasyceps bucklandi (Lloyd). 

 In 1849 G. Lloyd (49) gave a brief description of ' a new species 

 of Lahyrinthodon from the New Eed Sandstone of Warwickshire,' 

 which he named L. hucMandi. iSTo precise locality was cited ; 

 but the fossil was said to come from the Bunter Sandstone, near 

 Kenilworth. By Mr. HoAvell (59) and Sir Andrew Ramsay (55) 

 these rocks were placed in the Permian. 



Huxley (59) pointed out that the fossil was generically distinct 

 from any known Labyrinthodont ; he, therefore, proposed for it 

 the name Dasyceps. In the same year Huxley gave a detailed de- 

 scription, with two figures, of the skull of Dasyceps. Morris (54) 

 mentions this fossil, and Phillips (71) and Miall (75) follow Huxley 

 in their descriptions and figures. Eecently Baron E. von Huene (10) 

 has re-described and re-figured Dasyceps, which he considers to be 

 most nearly related to CocMiosauriis and other genera of the 

 Palaeozoic family of Melosauridae that are found in the Stephanian 

 Oas-Coal of Bohemia. Baron von Huene (08) has also described 

 a Pelycosaurian jaw from Kenilworth (now in the Museum of 

 Practical Geology) as Oxyodon hritannicus von Huene. 



Unfortunately, neither of these species has yet been recorded 

 elsewhere, and so they afford no definite evidence regarding the 

 exact age of the beds from which they come. 



The following fossils, which have never been figured or described, 

 are of doubtful specific and generic value : — 



Breea entassoides. I Caulerpites hiangularis. 



Caulerjpites ohlonga. \ Caulerpites triangularis. 



The Calaw.ites and Lepidodendron mentioned in the list on p. 607 

 cannot be specifically identified.

 wood from one of these tree-trunks from the Kenilworth Sand-
