BRITISH GRAPTOLITES. 



1874.

 few Graptolites from 

 the Lower Silurian 

 Rocks of Victoria," 

 Ann. Mag. Nat. Hist., 

 ser. 4, vol. xiv. 



An important addition to our knowledge of the Graptolitic 

 fauna of Australia was made by Etheridge, junior, in 1 874. 

 Several species are recorded, figured, and described: (1) 

 " Tetragraptus bryonoides" (Tetra. serra and Didymo. caduceus 

 (gibberulus) ), (2) Tetrag. quadribrachiatus, (3) Phyllog. typus, 

 (4) Loganograptus Logani (Goniograptus), (5) Climacog. sp., 

 (6) Diplog. mucronatus (Glossograptus and Lasiograptus), (7) 

 D. pristis, (8) Didymog. ? fruticosus, (9) D. nitidus, (10) D. Pantoni? (= D. v. 

 fractus), (11) G. fat us, which lie regards as a fragment of a Dichograptus, (12) 

 Graptolitlins sp. 



The same year M'Coy figured several fine examples of 

 Graptolites from Victoria in the first part of his ' Prodromus 

 of the Palaeontology of Victoria.' The only new form named 

 by him is a variety of G. Logani, i. e. (1) var. australis. 

 The other species are very similar to those given in Etheridge's 

 paper. (2) Phyllog raptus folium, His. var. typus, Hall, (3) Diplog. mucronatus 

 (= Glossograptus), (4) D. pristis, (5) D. rectangularis, (6) Diplog. (Glimacograptus) 

 bicornis, (7) Graptolithus (Didymog.) fruticosus, (8) Gr. (Didymog.) quadribraehiatus, 

 (9) Gr. (Didymog.) bryonoides, (10) Gr. (Didymog.) octobrachiatus. 

 1874. 



Lossen, during the same year, recorded Graptolites from 

 seven new localities in the Harz, corresponding in age to 

 the Upper Thuringian-Fichtelgebirge graptolite horizon.

Several additional forms of Australian Graptolites are given 

 in the second part of M'Coy 's " Prodromus," which appeared 

 in 1875. One new species is named : (1) Retiolites australis, 

 from the Wenlock. The other forms described and figured 

 are : (2) Didymog. exteusus, (3) (Didymog.) caduceus (under 

 this name are figured specimens of Didymog. gibberuius and Tetrag. Bigsbyi), 

 (4) Diplog. palmeus, (5) Gladog. ramosus, ((>) Gladog. furcatus. All these occur in 

 the Llandeilo. Gr. {Didymog.) gracilis, which he suggests might be made the 

 type of a new sub-genus, is recorded from the Bala. He refuses to accept the 

 genera Tetragraptus, Dichograptus, etc., considering that the number of stems con- 

 joined is a " character certainly not of generic value."

In a paper read before the Belfast Naturalists' Field Club 

 in 1875, Swanston recorded some fifteen species of Graptolites 

 from the Silurian strata at Coalpit Bay, co. Down.
