ART. 21 OEDOVICIAN TEILOBITES "ULRICH 13 



I am further convinced that Hadding's Swedish specimens that 

 he referred to T. hicuspis included cranidia of two distinct species. 

 Three of those figured by him under that name belong to the form 

 for which I propose the new name T. haddingi The remaining 

 fourth cranidium seems to represent a quite different species for 

 which I propose the name Telephus jamtlmidicus. Accordingly, I 

 propose that the three cranidia represented by Hadding's Figures 

 2, 3, and 4, in Plate 1, be given the rank of cotypes of T. haddingi, 

 whereas the original of Figures 1«, 16, Ic, and Ic?, in the same plate, 

 should rank as the holotype of T. jamtlandicus. 



Occurrence. — Lower part of the Ogygiocaris shale, Andereon, 

 Jamtland, Sweden.

Telephus hieuspis (part), Hadding, 1913, SUiktet Telephus Barr., Geolog. 

 Foren. Stockholm, vol. 35, p. 35, pi. 1, figs. la-Id, not 2-7, nor apparently 

 T. hicuspis Angelin. 



As mentioned previously it seems highly improbable that the cra- 

 nidium represented by Figures la-Id, Plate 1, in Hadding's work 

 on the genus is of the same species as the other specimens figured by 

 him at the same time and in the same plate as T. hicuspis. The 

 excepted cranidium is viewed as the holotype of the present species, 

 the others being the basis for the proposed T. haddingi. The former 

 differs from the latter in the shape of the glabella, this being wider 

 and more bluntly truncate anteriorly and its lateral sides straighter 

 than in the other. It differs from it also in lacking the low median 

 ridge that is plainly indicated in both the dorsal and anterior views 

 of all three of the cotypes of T. haddingi. Besides, the excavation 

 between the two anterior denticles seems wider. In short, Hadding's 

 figures of the two forms impress me as indicating two easily dis- 

 tinguishable species and leave the suggestion that T. jamtlandicus is 

 really a closer relative of the Scottish T. reedi than of the associated 

 T. haddingi. 



Occurrence. — Same as the preceding.
