The book is a valuable monograph : the topographical indications 

 are especially full and excellent. It is well printed and furnished 

 with a good coloured map and some sketch-plans. Only a resident 

 could have produced such a work. Jersey is to be congratulated on 

 possessing one both able and willing. E. Hill.

September 30th, 1886. — On Cretaceous Crustacea of Mount 

 Lebanon, by Herr Dames. 



Banina cretacea, sp. n., near the Eocene form B. marestiana ; 

 TencBus septem-spinatus, sp. n. ; Penceus Libanensis, Brocchi ; Ibacus 

 prcBcursor, n. sp. (a post-abdomen) ; Pseudastacus HaJcelensis, 0. 

 Fraas, very frequent, generic position not yet clearly ascertained, 

 as also of Pseudastacus minor, 0. Fraas. Sculda Syria ca, sp. n. ; 

 Sculda is the representative of a peculiar family, the oldest known 

 type of Stomatopoda. Sculda Icevis, Schloth. (:=Sqidlla Lewisi, 

 Woodw.), is the type of another family and genus — Pseudosculda, 

 Dames. Pseudosculdidce are known to exist in the Upper Cretaceous. 

 Sculdidce in the Upper Cretaceous and Upper Jurassic ; and genuine 

 Squillidae (Squilla cretacea, Schloth.) begin in the Upper Cretaceous, 

 and continue upward to the present time. 



LarvcB of crustaceans — Pseude?-ichtJius cretaceus and Protozoea 

 JBilgendorfi, sp. n., are very frequent near Sahel Alma. Limulus 

 Syriacus, Woodw., Loriculina Noetlingi, Dames, are found at Hakel. 

 The beds of both localities. Sahel Alma and Hakel, although 

 possessing a quite dijfferent Ichthyological and Crustacean fauna, 

 appear to be coeval ; and, considering the presence of Jurassic and 

 early Tertiary forms, may possibly be of Upper Cretaceous age. 

 The fauna of Hakel, notwithstanding the difference of age, offers 

 striking comparisons with the fauna of the Bavarian Lithographic 

 flagstones. It includes a few Post-Cretaceous types, such as Ibacus 

 prcecursor and Banina cretacea.

 in the Chair. — The following communications were read : — 



1. " On the Correlation of the Upper Jurassic Eocks of the Jura 

 with those of England." By Thomas Koberts, Esq., M.A., F.G.S. 



The author described at length his observations on the rocks of 

 the Jurassic system, from the Callovian to the Purbeckian inclusive, 

 first in the Canton of Berne, and then in the more southerly Cantons 

 of Neuchatel and Vaud. The sections in the former differed mate- 

 rially from those in the latter : the following stages were observed : — 

 North District. South District. 



Purbeckian. Purbeckian. 



Portlandian. Portlandian, 



Virgulian. ?
