BROAD-HEADED PLESIOSAURUS. 
181 
Plesiosaurus (?) dewalquii (Van Beneden). ^ 
The British Museum possesses (E. 1440) “ Three imperfect cervical vertebrie, 
cemented together by matrix ; from the Lower Lias of Barrow-on-Soar.” Pre- 
sented by Mrs. R. Etheridge, 1888. * 
Plesiosam'us (?) hawkinsi (Owen). 
The British Museum possesses (R. 45) “ A split slab of rock, shewing part of 
the skeleton of a small Plesiosaur, not improbably belonging to this species ; from 
the Lower Lias of Bennington. Referred to in Nichols’s ‘History of Leicestershire/ 
vol. i., p. ccv.” Presented by Major Harlowe Turner, 1880.* 
BROAD-HEADED PLESIOSAURUS. Plesiosaurus macrocephalus (Owen ex 
Conybeare). 
The Leicester Museum possesses, besides a few scattered bones, one magnificent 
example, seventeen feet in length, and rather more than seven feet in width 
from the extremities of the paddles, from the Lower Lias (planorbis zone), 
Barrow-on-Soar, purchased from the late Air. M^m. Lee, of Barrow, in 1851 or 
1852, by the Leicester Lit. and Phil. Soc., for the sum of one hundred pounds, 
and by them presented to the Museum. Prof. Ansted, who described it t 
under the name of Plesiosaurus megacephalus (in which error he has been 
followed by Mr. H. E. Quilter, in the “Lower Lias of Leicestershire,” p. 61 
‘Greological Magazine,’ decade iii., vol. iii.), pronounced it to be “worthy, not 
only of national, but of world-wide celebrity ” (see ‘ Report of the Leicester Lit. 
and Phil. Soc.,’ 1852, p. 14), Alentioned by Air. Harrison (‘ Greol. L. and R.,’ 
p. 37), who states that this species also occurred in the Limestone “ Bottom 
Floor” of a section of a pit between Barrow and Sileby, taken 1874. 
Plesiosaurus, Conybeare (sp. ind.). 
I find a head and vertebrae mentioned in Lee’s AIS. list of fossils from Barrow- 
on-Soar, as having been purchased from him by the Dublin Museum. The Derby 
Museum contains part of a jaw from Barrow. 
The Leicester Aluseum contains a rib, eighteen inches in length, found by 
Mr. Harrison in the Ehaetic bone-bed. Spinney Hills (see ‘ Greol. L. and R.,’ p. 35). 
This is included in the list of fossils from ‘The Rhaetics of Leicestershire,’ by 
Air. H. E. Quilter (see p. 17 ‘Trans. Leicester Lit. and Phil. Soc.,’ April, 1889). 
We also possess a humerus from the Lower Lias, Barrow-on-Soar. Quite lately 
(in 1889) the Messrs. Ellis presented the Aluseum with some vertebrae and parts 
of other bones which may be doubtfully ascribed to P. conybeari,
