Forh.,' no. 41, bd. 3. 



In 1877 Linnarsson recorded the presence of a large number 

 of speciesof Graptolites in the " Lobiferus shales" at Kongslena, 

 in Vestergotland. He only gives the names of those already 

 described, but mentions that there are others, probably new. 



1878.

Die Fauna des Grap- 



tolithengesteines," 



' Neues Lausitzisches 



Mag.' bd. 54. 



He discusses at considerable length the probable equivalents of those beds 

 in Great Britain, Bohemia, etc. 



Some addition to our knowledge of the fauna of the 

 " Graptolithengestein " of North Germany was made by 

 llaupt in 1878. He records 14 Graptolites, and the majority 

 are described and figured. One genus and species is new. 

 He describes, but gives no figures of, Monograpsus pri<><hm, 

 M. bohemicus, M. colonus and M. Sagittarius. He describes 

 and figures (1) M. distans ? (= M. scaniem Tullb.), (2) 

 M. Salted? Gem., (3) M. Nilssoni, (4) M. proteus? (5) M. sp. 1, and (6) sp. 2, 

 (unidentifiable), (7) M. turriculatus, (8) Rastrites sp., (9) Dendrograpsus sp. (10) 

 Quadruplograpsus rhomboidalis is the name given by him to a form which he 

 supposes to have four rows of cells. (The identity of this form is dubious, and it 

 would seem that the four-rowed character is only apparent, not real.) 



From other isolated blocks in the Drift he figures the new forms (11) Retiolites 

 gracilis, (12) Retiolites sp., (both Diplograptid, probably of the amplexicaul type) 

 and (13) Diplograpsus sp. (which resembles Cryptograptus).

Paleontology of 



Victoria,' dec. 5. 



1878. 



Lapworth, 



The Moffat Series,' 



' Quart. Jour ii. 



Geol. Soc.,' 



vol. xxxiv. 



The fifth part of M'Coy's ' Prodromus ' appeared in 1878. 

 Good specimens of Didymograptus (Goniograptus) Thureaui 

 are figured, and one of Didymograptus (Tetragraptus) Headi. 



In this year Lapworth published a paper on the " MolT.it 

 Series of South Scotland." In this memoir the species of 

 Graptolites are for the first time employed throughout in the 

 grouping and correlation of the stratigraphical subdivisions; 

 and the conclusion is drawn that this Moffat Series, which is 

 only some 300 feet in collective thickness in the typical area,
