THE REPTILES OF LEICESTERSHIRE AND RUTLAND. 
long, wanting the greater part of both extremities. I cannot describe it to you 
better than in the words in which the Professor was pleased to acknowledge the 
receipt of it. “ I have now to thank you for your magnificent present to our 
INIuseum of an extremely fine Ichthyosaurus, more perfect in its display of the 
bones of the sternum than any specimen I have ever seen ; and which I hope 
to disengage from much of the stone in which it is now embedded.” — He did 
so, and afterwards delivered some public lectures upon it, having, in his micro- 
scopic examinations of it, made, for the first time, the important discovery of 
the skin of this remarkable fossil. Of this he has given an accurate description 
in p. 22, vol. ii., of his Bridgewater Treatise, with drawings of the same in plate 10 
of the same volume.’” Professor A. H. Green, M.A., F.G.S., kindly informs me 
that this specimen is in the Oxford Museum, but as yet undetermined. 
The Leicester Museum possesses remains, including two femora, two humeri, 
and several vertebrae from the Lias, Barrow-on-Soar, and several large vertebrae 
found by hlr. Harrison in the Ehaetic bone-bed. Spinney Hills, where were also 
found several teeth and coprolites, many of the latter containing fish-scales (see 
‘ Geol. L. and K.,’ p. 35), and Mr. E. Wilson, F.G.S., Curator, Bristol Museum, 
records (‘Mid. Nat.,’ vol. viii., p. 158) a vertebra, found in the Middle Lias 
hlarlstone at Tilton-on-the-Hill, and kindly presented by him to the Museum. 
The British Museum possesses (R. 1200) “ Slab exhibiting the left lateral 
aspect of the hinder part of the caudal region ; probably from Barrow-on-Soar.” * 
The Dublin Museum possesses six portions of skulls and other parts from the 
Lower Lias of Barrow-on-Soar, purchased from the late IMr. Wm. Lee. 
Order SAUROPTERYGIA. 
Family PLE SIO S AURID^. 
Thaumatosauims megacephalus (Stutchbury). 
I find, in Lee’s IMS. list of fossils from Barrow-on-Soar, a specimen 13 feet in 
length mentioned, under the name of Plesiosaurus megacephalus, as having been 
purchased from him by the Dublin Museum ; but I have no means of knowing 
whether this has been correctly determined, or, as is probable, should be attributed 
to Plesiosaurus macrocephalus, Mr. Ball informing me that their reptiles have 
not yet been properly referred. 
Cimoliosaw'us (?) truncatus (Lydekker ex Owen). 
In Rutland. — The British Museum possesses (44904) the greater portion of 
a mandible, which is not improbably of this species ; from the Great Oolite of 
Essendine.*
