 that this Shropshire succession will form the general standard 

 to which all other British Ordovician strata must ultimately be 

 referred.

 at Brandley Mine and Saltwell Park, and a chalybeate spring at Wood-

 remarks on " Purple-grey Carboniferous Rocks and the Whitehaven 

 Sandstone" (pp. 146-148). He points out that purple-grey rocks, 

 similar to the Whitehaven Sandstone, occur on almost every horizon 

 throughout the Carboniferous series in Cumberland.

I. — M. DoLLo's Notes on the Dinosaurian Fauna op Bernissart. 



rilllE remarkable preservation of a Pauna of Wealden reptiles at 

 X Bernissart has been utilized with admirable skill, so that the 

 skeletons, though necessarily extracted in fragments, have been 

 again reunited in the anatomical I'elations of the bones, in the 

 Brussels Museum, under the able direction of M. de Pauw. 



The animals thus displayed in a perfection which no other reptile 

 fauna in Europe can surpass have been the subject of a series of 

 valuable preliminary memoirs by M. Dollo, published during the 

 last few years in the Bulletin du Musee Eoyal d'Histoire Naturelle 

 de Belgique. The object in issuing these notes, in anticipation of 

 the full description which is to follow, is professedly to gain from 

 the criticism of scientific men suggestions which may aid in the 

 perfection of the final monographs. I gladly avail myself of this 

 opportunity for drawing attention to the excellent work which 

 M. Dollo has thus far performed ; and at the same time ojEfer a few 

 suggestions upon points where a difference of opinion seems to me 

 legitimate. 



The great interest of this work centres in the Dinosaurians, which 

 were examined by M. Boulanger, and referred to the Iguanodon 

 MantelU, and a new species named by him lyuanodon Bernissartensis, 

 in days before M. Dollo commenced his labours. 



The author begins bj'' contrasting the differences between these 

 two forms. Separating the characters of the animals, we are able to 

 define the two types thus : Iguanodon MantelU is a relatively small 

 and slender animal, with a skeleton nearly twenty feet long. Its 

 skull, 50cm. long, is relatively elongated, being moderately deep, 

 and three times as long as wide. The anterior nares are long 

 narrow vacuities, half as long as the lower jaw, and descending 

 anteriorly for some distance over it. The orbit for the eye is rather 

 longer than deep. The temporal vacuities, seen from above, are
