TELEPHUS BICUSPIS Angelin 



Plate 2, Figures 20, 21 



Telephus hlcuspis Angelin, 1854, Palaeontologia Scandinavica, p. 91, pi. 41, 

 figs. 22, 22a. 

 Probably rfot Tclcplius hicuspis of Hadding. 



My conception of this Norwegian species is based entirely on the 

 figures given of it by Angelin and herein reproduced. Hadding 

 identifies the species in Sweden and figures a number of cranidia 

 from there under this name. But it seems almost impossible that 

 Angelin ^- could have so poorely represented the characters of his 

 species as appears on comparing his dorsal and anterior views of the 

 cranidium with the corresponding Adews of the Swedish specimens 

 that Hadding refers to the species and describes and figures, evi- 

 dently accurately, in his work on the genus. The validity of this 

 doubt is further indicated by the fact that Angelin's figures of the 

 other two of his species {T. (/ranulaius and T. wegelini) are far less 

 discordant with the figures given of them in Hadding's paper than 

 in the case of T. hicusjns. 



Under the circumstances I have decided to reproduce Angelin's 

 original figures of T. hicuspis wdthout further comment and to pro- 

 pose other names provisionally for the Swedish specimens that Had- 

 ding referred to this species but which it seems to me are not only 

 distinct from it but are themselves divisible into two species. 

 Remarks concerning these follow. 



Occurrence. — Angelin's type of the species came from some local- 

 ity in northern Norway, probably near Mjosen where Holtedahl lists 

 the species as a common fossil. 



TELEPHUS HADDINGI, new species (provisional) 



Plate 1, Figures 11-18 



Telephus bicuspis (part), Hadding, 1913, Slaktet Telephus Barrande, 

 Geolog. Foren. Stockholm, vol. 35, p. 35, pi. 1, figs. 2-7. 

 Apparently not Telephus Mcuspis Angelin. 



My information concerning this proposed new species is based 

 entirely on illustrations in Hadding's work of Swedish specimens 

 referred by him to Angelin's Norwegian species, T. bicuspis. As 

 mentioned in foregoing remarks on the latter, it seems highly im- 

 probable, not to say impossible, that the Swedish specimens figured 

 by Hadding under that name are of the same species as Angelin's 

 T. bicuspis. Both Angelin's and Hadding's illustrations are photo- 

 graphically reproduced on Plates 1 and 2 so that the reader may form 

 his own conclusions regarding the specific relations of the concerned 

 specimens.
