 Mr. W. E. Brodie in tbe "Wealden of Pimfield Bay, Swanage.

TIjyper Cretaceous. 



(Gault). 



In April, 1876, M. Charles Brongniartf called the attention of 



the Entomological Society of Erance to a piece of fossil wood, obtained 



from the Gault of Lottinghem, Pas-de-Calais, containing numerous 



perforations. 



M. Brongniart was of opinion that these perfoi'ations were made 

 by a species of beetle, belonging to the genus Hylesiyms, of the family 

 ScolytidcB {X:iilopliaga^. 



( Greensand) . 

 Remains of perforated wood have also been discovered in the 

 Grreensands of Saxony, which are considered by Dr. Geinilz| to be 

 evidence of the existence of Longicorn beetles at this Period. 



{GhaJk Marl and White Chalk). 



Erom certain beds of sand in the neighbourhood of Aix-la-Chapelle 

 — which, according to Lyell,§ are of the same age as the White Chalk 

 and Chalk Marl — about ten species of Coleoptera have been obtained, 

 all of which have been referred to the Curculionidce and Caralidce. 



Prof. Pictet|| also alludes to the discovery of a few elytra of 

 Coleoptera in the Chalk Marl in the neighbourhood of Eouen. 



With the exceptions above mentioned I am not aware that any 

 remains or traces of the Insect fauna of the Cretaceous Period have 

 been discovered, either in the United Kingdom or on the continent of 

 .Europe. 



The other Arthropoda of the Period are represented by Crustacea, 

 chiefly Macrurous and Brachyurous Decapoda (lobsters and crabs), and 

 probably also by Arachfiida and Myriopoda, though no traces of them 

 have been recorded. 



The MoUusca include the Orders Folyzoa, BracMopoda — the 

 number of genera and species of which last Order has sensibly de- 

 declined^ — Lamellihranchiata, Gasteropoda, and Cephalopoda. 



Of the Vertehrata, the fishes are represented by Ganoids and 

 Placoids, and also by the earliest known specimens of the modern
