_Philosophical Magazine_ he contributed many geological memoirs. In 1821
he distinguished himself by the description of a skeleton of the
_Plesiosaurus_, discovered by Mary Anning, and his account has been
confirmed in all main points by subsequent researches. Among his most
important memoirs is that on the south-western coal district of England,
written in conjunction with Dr Buckland, and published in 1824. He wrote
also on the valley of the Thames, on Elie de Beaumont's theory of
mountain-chains, and on the great landslip which occurred near Lyme
Regis in 1839 when he was vicar of Axminster. His principal work,
however, is the _Outlines of the Geology of England and Wales_ (1822),
being a second edition of the small work issued by William Phillips
(q.v.) and written in co-operation with that author. The original
contributions of Conybeare formed the principal portion of this edition,
of which only Part I., dealing with the Carboniferous and newer strata,
was published. It affords evidence throughout of the extensive and
accurate knowledge possessed by Conybeare; and it exercised a marked
influence on the progress of geology in this country. He was a fellow of
the Royal Society and a corresponding member of the Institute of France.
In 1844 he was awarded the Wollaston medal by the Geological Society of
London. The loss of his eldest son, W. J. Conybeare, preyed on his mind
and hastened his end. He died at Itchenstoke, near Portsmouth, a few
months after his son, on the 12th of August 1857. (Obituary in _Gent.
Mag._ Sept. 1857, p. 335.)

His elder brother JOHN JOSIAS CONYBEARE (1779-1824), also educated at
Christ Church, Oxford, and an accomplished scholar, became vicar of
Batheaston, and was professor of Anglo-Saxon and afterwards of poetry at
Oxford. He likewise was an ardent student of geology and communicated
several important papers to the _Annals of Philosophy_ and the
_Transactions of the Geological Society_ of London. (Obituary in _Ann.
Phil._ vol. viii., Sept. 1824, p. 162.)

CONYBEARE, WILLIAM JOHN (1815-1857), English divine, son of Dean W. D.
Conybeare, was born on the 1st of August 1815, and was educated at
Westminster and at Trinity College, Cambridge, where he was elected
fellow in 1837. From 1842 to 1848 he was principal of the Liverpool
Collegiate Institution, which he left for the vicarage of Axminster. He
published _Essays, Ecclesiastical and Social_, in 1856, and a novel,
_Perversion, or the
