THE REPTILES OF LEICESTERSHIRE AND RUTLAND. 
Although I have not met with it, I cannot think Harley could have confused 
it with the preceding common species, for he expressly stated (speaking of 
“ Lacerta ” vivipara) : — “ The species appears in the spring much about the same 
time as the Sand Lizard, but its reproduction is very diverse from it, since it is 
ovoviviparous, while Lacerta stirpium is oviparous only,” which shews that he 
recognised the characteristics of the two species, and was not misled by considera- 
tions of colour or habitat. 
Family S C I N C I D ^ . 
BLIND-M^’OEM. Anguis fragilis, Linnaeus. 
“ Slow- Worm.” 
Resident and commonly distributed. — There are specimens in the Museum 
from Charnwood Forest, Bardon Hill, and other places. 
Order ICHTHYOPTEEYGIA. 
Family I C H T H Y 0 S A U R I D 
ICHTHYOSAURUS. Ichthyosaurus communis (Conybeare). 
Professor Owen noted in the ‘Rep. Brit. Assoc.’ for 1839, p. 110, an entire 
skull from the Lower Lias of Barrow-on-Soar, which is still preserved in the 
Museum of the Philosophical Institution at Birmingham. The British Museum 
possesses a cast from this (14593).* He also figured, in the ‘ Trans. Geol. Soc.,’ 
ser. 2, vol. vi., pt. i. pi. xx., and in his ‘ Liassic Reptilia ’ (Alon. Pal. Soc.), pt. iii., 
pi. xxviii., fig. 3, a slab, shewing the impressions of the bones and of the integument, 
together with some of the bones themselves, of an imperfect pelvic paddle, probably 
belonging to the present species, from Barrow-on-Soar. The distal portion is 
entire. It is also figured by Mantell in his ‘ Petrifactions and their Teachings,’ 
p. 374, fig. 76, and by Kiprijanoff in the ‘Mem. Ac. Imp. St. Petersbourg,’ 
vol. xxviii., art. 8, pi. ix., fig. 12 (1881). The original was presented by Sir Philip 
de Malpas Grey Egerton, Bart., in 1855, to the British Museum, where it still 
remains, and is numbered 29672.* 
I am greatly indebted to Mr. Valentine Ball, M.A., F.R.S., F.G.S., Director 
of the Science and Art Museum, Dublin, for kindly forwarding me the original 
list of the late Mr. Wm. Lee’s fossils, which, it is stated thereon, were “ Examined 
and named, etc., by Professor Etheridge, Nov. 21st, 1867,” by which it appears 
that the Dublin Museum possesses thirteen specimens of I. communis, ranging 
in length from 3 ft. 2 in. to 7 ft. 9 in., and also four crania referrible to this 
species- — all from Barrow-on-Soar. The Derby IMuseum also possesses one from 
the same place, so I am informed by Mr. H. Arnold-Bemrose, F.G.S.
