Formation* of the Haotpshm !> 127 



To the above list of reptiles must be added bones belonging to 

 an unknown Lizard, and vertebras of an Ophidian. 



The above specimens of Trionyx and Emi/s are in the cabinet 

 of the Marchioness of Hastings, and I cannot cite these valuable 

 relics which I had the privilege of attentively studying without 

 at the same time acknowledging her ladyship's courtesy, and 

 bearing my humble testimony to the judgement and skill dis- 

 played in restoring the numerous fragments of these Chelonians 

 to their proper places in the skeleton, a task which the Marchioness 

 has achieved with matchless patience, neatness, and tact. 



Fishes. 



Very perfect specimens of Lepidosteus have been found. The 

 dermal scales are very abundant, many of which, with portions of 

 the jaws and teeth, are strewed throughout the bed. 



In the cabinet of Lady Hastings are many beautiful specimens 

 of this eocene ganoid fish. 



Mollusks. 



Potamomya plana, Potamides margaritaceus, and Melania conica 

 are found sparingly. 



The reptilian bones lie chiefly in the lowest 12 inches of the 

 sand, but separate vertebrae and a great number of dermal plates 

 are strewed throughout the entire bed. 



No. 11. Light green marl striped with gray, ochre and red 

 tints, containing a few Potamomya angulata ; fossils not nume- 

 rous : 5 feet 6 inches. 



No. 12. Gray Sand passing into dove-coloured white when 

 dry. Contains many seams of shells. The most abundant fossil 

 is Potamomya plana. The blocks of this bed that lie along the 

 base of the cliff, split at the shelly layers into slabs of from half 

 an inch to an inch in thickness. The surface of these is covered 

 with single valves of Potamomya. It is rare to obtain specimens 

 with the valves united. In this bed are likewise found many 

 fragments of the bones of Palaotheria and Trionyces. It i> n- 

 markable that the osseous reliquia of this bed are nearly all 

 rounded and much bouldered. It measures about 4 feet. 



No. 13. The " Leaf -bed" consists of a slate-coloured clay, which 

 contains the impressions of leaves of Dicotyledonous plants in 

 considerable number and variety of species ; it contains likewise 

 fossil fruits and the stems of plants ; but we could not discover any 

 shells. This well-marked bed rises nearly opposite Hordle Hooflfi, 

 ami runs out at Long Mead End. Thickness about 18 inches. 



No. 14. Bluish sandy clay forms the lowest bed of the fin 

 water series, and runs out at Beacon Bunny. This stratum is very 

 uniform in its lithological character throughout. In one part 

 of its course it makes a sudden dip from 3° to 10°. It is tra-
