320 Lauhe — Fossils of the Brawn Jura. 



rostral portion originally limited by furrows, as in the genera Tdio- 

 caris, Salt., and Discinocaris, Woodw. It must be remarked that 

 all other forms of Phyllopods, the actually liviag genus Apus excepted, 

 are Palaeozoic. Aspidocaris, Eeuss, stands next to Discinocaris, 

 Woodw. 



Halycine elongata, Eeuss, from the same limestone, — a dorsal cara- 

 pace badly preserved. The three or four species of the Poecilopod 

 genus Halycine at present known, all belong to the Conchiferous 

 Limestone, or to the Inferior Keuper. 



Oyihere fraterna, Eeuss, from the shales of Eaibl Carinthia, which 

 also abound in plants, Decapod Crustacea, and fishes. Isolated valves 

 of an Ostracod, nearly related to Gyihere Bichteriana, from the 

 Zeohstein, are of some interest as being the earliest remains of this 

 Crustacean stated to occur in the Alpine Trias. — [Count M.] 



V. ^DlE BlVALVBN UND DIE EcHINODEKMEN DES BeAUNEN JuRA VON 



Balin. By Dr. Gustav C. Laube. Wien, 1867. 



THESE two papers by Dr. Laube are in part a continuation of the 

 pal^ontological researches commenced by Professor E. Suess, 

 on the fossils of the Brovni Jura of Balin, in Poland. The papers 

 contain descriptions and carefully prepared illustrations of the EcJiino- 

 derms and bivalve shells found in the Lower Oolite of that locality, 

 and are interesting as showing the wide range of some species of 

 the Oolitic fauna. Five species of Echinoidea, belonging to the genera 

 Clypeus, Collyrites, Echinobrissus, Hyboclypus, and Holectypus, are 

 common to Balin and the Lower Oolites of England. Of the Conchi- 

 fera about seventy species from Balin have been identified by Dr. 

 Laube as occurring in the Inferior and Great Oolite and Combrash of 

 England. The curious genus Elignius of Deslongchamps is repre- 

 sented by two species, and under Cardiodonta of Stolitczka, are 

 included certain forms placed by Sowerby and Miinster in Isocardia. 

 The genera Tancredia, Sowerbya, and Gresslya are also represented.

VI. — ^NoTES ON A New Genus of Fossil Crustacea. By F. B. Meek. 



ANEW Crustacean, from the Coal-measures of Illinois, was 

 described in 1865, by Messrs. Meek and Worthen, under the 

 name of Belinurua Dance ; it differs, however, in some respects from 

 the characters usually assigned to that genus. Having since seen 

 the paper by Mr. H. Woodward on the Structure of the Xiphosura 

 (Quart, Joum. Geol. Soc, Vol. xxiii.), in which that group is now 

 divided into three genera — Mr. Meek has been led to refer his 

 Belinurus Dance to a new genus, holding an intermediate position 

 between Belinurus and Prestwichia ; for this he proposes the name 

 Euproops, in allusion to the anterior position of its eyes. This form 

 is at once distinguished from the now restricted genus Belinurus, by 

 its anchylosed abdominal segments and the anterior position of its 

 eyes, as well as by the more oval or sub-circular outline of its abdo- 

 men. From Prestwichia, with which it more nearly agrees in general
