ICHTHYOSAURUS CONYBEARI — ICHTHYOSAURUS INTERMEDIUS. 
177 
The Leicester Museum possesses three specimens of this reptile — one about 
6 feet 6 inches in length, nearly perfect, shewing part of the eye with sclerotic 
plates — purchased from the late Mr. Lee ; the jaw with teeth of another, presented 
by Mr. T. F. Bell some years since, all from the Lower Lias (planorbis zone), 
Barrow-on-Soar, and a jaw, shewing very perfect teeth, from the Vale of Belvoir. 
The species is also mentioned, at p. 349 ‘ Catalogue of British Fossils,’ by John 
Morris, F.Gr.S. (1854), from the “ Lias of Barrow-on-Soar,” and by Mr. W. J. 
Harrison, F.G.S. (‘ Geology of Leicestershire and Rutland,’ p. 37), as having been 
found in the Limestone “ Good-for-nought,” in a section of a large pit between 
Barrow and Sileby, in 1874. 
Ichthyosaurus conyheari (Lydekker). 
First described by Mr. Lydekker in the ‘ Geol. Mag.,’ dec. 3, vol, v., p. 311 
(1888), who further says; — “It is not improbable that the skeleton in the 
Woodwardian Museum, Cambridge, from the Lower Lias of Barrow-on-Soar, 
recorded as No. 11 on page 138 of Seeley’s ‘Index to Aves, etc., in Cambridge 
Museum ’ (1869), belongs to the present form.”* 
Ichthyosaurus intermedius (Conybeare). 
The Dublin Museum contains three specimens — the largest being 8 feet 
3 inches in length — from Barrow-on-Soar ; purchased from the late Mr. Wm. 
Lee. The species is mentioned also by IMorris (‘ Catal. Brit. Foss.’), and by 
Mr. Harrison (p. 37, ‘ Geol. L. and R.’), as having been found in the same pit 
and position as I. communis. 
The Leicester IMuseum possesses a specimen of this reptile, nearly perfect, 
10 feet in length, from the Lower Lias (planorbis zone), Barrow-on-Soar, which, 
if correctly determined, is the largest yet known, IMr. liydekker recording this 
species as not exceeding seven feet. A limestone nodule from the same place, 
presented by the IMessrs. Ellis, I caused to be split, and found it to contain the 
greater part of the head and jaws and the fore paddles of an Ichthyosaurus, which 
hlr. Ijydekker, who has kindly referred the reptilian remains for me, pronounces 
to be of this species. 
I wish here to record my grateful thanks to the Messrs. Ellis for affording 
me unusual facilities for systematically working the Barrow quarries ; and it 
was on the occasion of one of my periodical visits, viz., on 5th July, 1889, that, 
through the instrumentality of Mr. John Raven, the courteous manager, whom 
I have to thank for many kindnesses, I became possessed of a nodule containing 
part of the thorax and paddle of I. intermedius, which, on being split, was found 
to exhibit some unusual markings. During the cleansing, Mr. W. P. Pycraft, my 
assistant, called my attention to an appearance on the anterior margin, which
