DINOSAURIA. 
Rept. 5 
L. Dollo contributes two further papers on the Bernissart Iguano- 
dons. In his third note, the author gives a complete restoration 
of Iguanodon bernissartensis, describing more specially the pelvic arch 
and the hind limb ; he also remarks on the footprints discovered in other 
countries, and pronounces those from the Wealden of Hanover, described 
by Struckmann, to belong to I. mantelli. The author concludes by 
stating that the mode of life of the Iguanodons was more aquatic than 
terrestrial, and that, on land, they progressed on their hind limbs only.

In his fourth note, the skull of Iguanodon bernissartensis is figured and 
described, and the principal characters of the vertebral column are 
given. In an appendix to this paper, the characters assigned by Cope to 
the skull of Diclonius mirabilis are compared with those of Iguanodon.

J. W. Hulke, in his anniversary presidential address to the Geological 
Society, enters into some details respecting the Iguanodons of Bernissart. 
Iguanodon seelyi is probably identical with I. bernissartensis. The 
restoration of the sternal apparatus given by Dollo is discussed, aud an 
ideal restoration with the “sternal bones” placed as “ clavicles” is given.

Ortliomerus , g. n., apparently intermediate between Iguanodon and

xxxix. p. 248, Maestricht beds. L. Dollo, Bull. Mus. Belg. ii. p. 205, 
woodcuts, describes and figures vertebrae of the same animal. 
E. D. Cope has an extensive preliminary paper on the characters of 
the skull of the Hadrosauridce , with special reference to Diclonius 
mirabilis , Leidy, which is figured. He criticizes Marsh’s recent essay of 
classification of the group Dinosauria , which he maintains as an Order 
divisable into four suborders, viz., Opisthocoda , Owen (= Sauropoda , 
Marsh), Orthopoda , Cope (= Stegosauria and Ornithopoda , Marsh), 
Goniopoda , Cope, and Hallopoda, Marsh. P. Ac. Philad. 1883, pp.
