96 THE POIKILITIC PERIOD. CHAP. 



The silicified wood found at Allesley belonged to large trees 

 (coniferse), and was described by Dr. Buckland, in a paper read 

 to the Geological Society, in 1836. 



The specimens referred to Lepidodendron, Sternbergia, and 

 Calamites, found in sandstone at Exhall, may be regarded as con- 

 firming the general analogy of the Permian fossils with those of 

 the carboniferous system, and the same conclusion is supported 

 by the Strophalosia, a genus allied to Producta, found at Exhall, 

 and the corals and crinoids, as far as they have been determined, 

 found at Kenil worth. 



The remarkable cranium of a fossil reptile, formerly described 

 by Dr. Lloyd as Labyrinthodon Bucklandi 6 , appears, by later 

 examination of Professor Huxley, to require separation from the 

 rather unsettled generic group to which it was referred. He has 

 named it (from the roughness of the surface) Dasyceps Bucklandi f . 

 The cranium, between the extremities, is 10 inches long, and 

 9J broad. Diagram XXV. fig. i, taken from Professor Huxley, 

 shews the small round orbits placed far back, and between them 

 the parietal foramen; in front the small round nostrils are seen 

 widely separated, and between them the long oval facial fontanelle, 

 bounded by the pre-maxillary, nasal, and anterior frontal bones. 

 The sutures are to a considerable extent traceable, though the fossil 

 is not in a favourable state for minute scrutiny. The quadrate 

 bones at the base of the isosceles triangle formed by the cranium 

 shew how broad was the opening of the jaws. The occipital bone 

 projected retrally in two remarkable ridges, which were supposed, 

 at first, to be the double condyles of a labyrinthodont. The real 

 condyles have not, it appears, been discovered. Teeth slender, 

 curved, striated. 



The country about Warwick and Leamington and Coventry shews 

 the same series of red beds as that near Worcester, not excepting 

 the Keiiper. In addition, the sandstones are more fully exhibited, 

 and yield more numerous and more characteristic remains of large 

 reptiles ; Labyrinthodon and Cladyodon, among others frequent 

 in the country near Warwick, are well exhibited in the museum 

 of that town.
