The name Climacograptus a n t i q u u s was 

 originally proposed for a species in a paper read by 

 Lapworth in 1873, on the Diprionidae of the Moffat 

 shale. Only the list of species being published, the 

 name remained a uonieu nudum and the species as such 

 has to my knowledge never been figured or described. 

 Professor Lapworth has later informed Dr Gur- 

 ley that the same form has repeatedly been 

 figured by him as C . caelatus I see foregroingr

synonymy]. It is on these figures that the 

 Z. species has to be based until an original descrip- 

 tion of Scottish material is published. 



In his preliminary Report on Graptolites 

 .iS«.^pwo^ m Fi"^ a iap#ortj?.' from the St Lawrence, Lapworth has cited the 



manuscript drawing (x 6%). Fig. 408 Por- • r

 in Nevada. Later Gurley has also recognized it with some doubt due- to 

 the poor preservation of his material from the equivalent graptolite shales 

 of the novaculite region of Arkansas and we have before us two well pre- 

 served specimens from the shales associated with novaculite in the Talihina 

 formation in Indian Territory that seem to accord best with Lapworth's 

 figures.
