The author also remarks, p. 63, on the genera Rhamphorrhynchus and 
Pachyrrhamphus , which, as well as Dimorphodon, Dorygnathus, and 
Ornithochirus , he is inclined to consider as subgenera of one genus, 
Rhamphorrhynchus.

O. C. Marsh, Am. J. Sci. (3) xxiii. pp. 81-86, and Ann. N. II. (5) ix. 
pp. 79-84, proposes the following classification of the Dinosauria , which 
group is raised to the rank of sub-class : — 
Ord. I. Sauropoda. 
Fams. Atlantosauridce, Morosauridai. 
Ord. II. Stegosauria. 
Fams. Stegosaurida ?, Scelidosauridm. 
Ord. III. Ornithopoda. 
Fams. Camptonotidce , Iguanodontidce , Iladrosauridce. 
Ord. IV. Tiieropoda. 
Fams. Meg alosaur idee, Zanclodontidce, Amphisauridce , Labrosau- 
ridce , Cceluridce , Compsognatliidcc. The two latter form two 
suborders, viz., Cccluria and Gompsognatha. 
Ord. V. ? Hallopoda. 
Fam. Hallopodidcc. 
The latter order is referred with doubt to the Dinosauria.

L. Dollo inaugurates a series of notes on the Dinosaurs of Bernis- 
sart, Belgium. In a first paper, the author establishes the specific 
distinctness of two forms of Iguanodon occurring in the Wealden of 
Bernissart, viz., I. mantelli, Owen, and I. bernissartensis , Blgr., and gives 
comparative figures of the fore limb aud pectoral arch, and the hind limb 
and pelvic arch in the two species. He expresses himself on the natural 
position of the genus Iguanodon , and proposes a new arrangement for 
the group Ornithopoda, showing also that the characters ascribed by 
Marsh {supra) to his family Iguanodontidce , were the result of misinter- 
pretation and misinformation. The order Ornithopoda is divided by 
Dollo into 3 families, viz., Iguanodontidce , Hypsilophodontidce, and Hadro - 
sauridce. Bull. Mus. Belg. i. pp. 161-180, pi. ix.
