CI. brevis, Gl. supernus, and G. latus, together with several 



Annotated lists of Graptolites identified by the author 

 from many localities in Victoria, with figures and descrip- 

 tions of three new species : < 'limacograptus mensuris, ( '. 

 Baragawanathi, and Diplograptus ingens. 



An excellent summary of the results of the author's field- 

 researches in a most complicated district. The paper is 

 illustrated by a geological map of the area described and 

 tables of fossils, etc. The stratigraphical succession, which 

 extends from Middle Arenig (Didi/mograptus bifidus zone) 

 to the Lower Llandeilo (Llandovery) inclusive, is rich in 

 Graptolites on several horizons. Fifty-four species are 

 recognised by the author, and their localities and ranges given. 



A description of the results of a combined field-study of 

 the strata and fossil contents of the Lower Palaeozoic Rocks 

 of Portlock's classic district of Pomeroy, North Ireland. 

 Especial attention is paid to the zonal sequence of the in- 

 cluded forms of Graptolites, of which thirty-four species and 

 varieties are named from the Pomeroy formations, and their 

 sequence and correlation given in an accompanying table. 



The author gives a table of some twenty-five species and 

 varieties of Graptolites collected from the Lower Palaeozoic 

 rocks on the Italian versant of the main range of the Carnic 

 Alps, and assigns the containing beds in part to the Llan- 

 dovery and in part to the Wenlock-Ludlow. The majority 

 of the forms are referred to well-known British species, but 



three are noted as new : Dendrograptus (?) carnicus, Desmograptus italicus, .V. 



colonus, (Barr.) var. intermedius. A brief bibliography introduces the work. A 



description of each species and an accompanying plate allows of the identification 



of most of the forms represented. 



The author noted the discovery of I'leurograptiis linearis 

 (Can'.) in the Dicellograptus Beds of Scania, and discusses 

 and tabulates in zonal form the whole of the Ordovician of 

 Scania, parallels the Trilobite-facies and Graptolite-facies. 

 and recognises under distinct names some fourteen Graptolite 

 Zones in the general sequence. 

 Founding mainly upon collections made by himself in Sweden and Central 

 Europe, supplemented by examples collected by Herr Eisel of Gera, Thuringia,
