as is occasionally met with in the Kellaways Rock. On picking 

 up further pieces, however, it became evident that they were 

 small fragments of bone. Subsequent visits were the means of 

 finding" still more specimens, chiefly whole and broken vertebrae, 

 pieces of ribs, etc. On one of these occasions I was fortunate 

 enough to find a vertebra protruding from the quarry face, at 

 a depth of about seven feet ; this was in close proximity to the 

 heap from which the other remains had been collected. With 

 the assistance of a pick this bone was extracted, and, as might 

 be expected, several others were found, on the same level, 

 fitting close together. These vertebrae were nearly circular and 

 without the prominent processes which occurred on some of the 

 earlier specimens found on the refuse heap. Evidently, there- 

 fore, we had got to the tail end of the animal, and unfortunately 

 the most important remains had already been excavated and 

 were not preserved. However, the find in the quarry face 

 enabled the exact position of the animal in the rock to be fixed, 

 and there can be little doubt that the almost complete skeleton 

 of a huge saurian had been buried in the quarry, where it had 

 rested undisturbed from the day it was deposited during Jurassic 

 times. Some large paddle bones were obtained by Mr. W. 

 Richardson, and these Mr. Richardson has been good enough 

 to hand over to me. 



The specimens were forwarded to Mr. E. T. Newton, F.R.S., 

 Palaeontologist to the Geological Survey, who has kindly ex- 

 amined them for me. He reports that they ' belong to some 

 animal allied to the Plesiosaariis, and probably to the one which 

 has been named Cryptocleidus , but the broken condition of the 

 specimens prevents a certain determination.' Mr. Newton adds, 

 ■ such reptiles are known from the Oxford Clay, but not from 

 the Kellaways Rock,' and I have a letter from Mr. C. Fox- 

 Strangways, author of the 'Jurassic Rocks of Yorkshire,' to 

 the same effect. 



The fossils have been determined as follows : — Parts of 

 paddle-bones, femur or humerus ; paddle ossicles ; piece of jaw ; 

 portions of vertebrae ; and ribs. The portion of the jaw is very 

 interesting, but unfortunately is only the anterior half of the 

 lower jaw, and does not contain any teeth. In addition to 

 the above, which represent the specimens sent to London, there 

 are dozens of pieces of bone, though principally vertebrae and 

 ribs. Reference to a restoration of a Plesiosaurus in any "of the 

 geological text books will make the reason for the abundance of 

 pieces of ribs and vertebrae obvious enough.
