TELEPHUS BUTTSI, new species 



Plate 5, Figure 16 



The holotype of this perhaps doubtful species is a very small 

 cranidium with an extremely long, slender, and rounded occipital 

 spine. Two other, in all respects similar, cranidia were found with 

 it in the same slab of shale. Slight variations in shape of these three 

 specimens and in associated fossils of other classes indicate that the 

 figured holotype has suffered sufficient compression to have reduced 

 its original longitudinal dimensions by possibly a fourth. On realiz- 

 ing this its resemblance to T. hipunctatus^ which has been noted 

 already by comparison of their respective illustrations in Plate 5, is 

 correspondingly enhanced. Possibly it actually belongs to that 

 species, in which case the extraordinary length of the occipital spine 

 would be merely a character of youth. However, it is not so easy to 

 explain the sharply angular post-lateral extremities of the glabella 

 and also the greater obliquity and more posterior position of the pair 

 of glabellar furrows. The anterior spines also are more divergent 

 and more prominent in dorsal views than in T. Mpunctatus. For 

 these reasons it seems best to treat these small specimens as represen- 

 tatives of an independent species. It is named for Dr. Charles Butts, 

 who discovered the outcrop of shale in which they and many other 

 interesting fossils were found by him and subsequently by Mr. R. D. 

 Mesler. 



Occurrence. — The types of T. buttsi and also the specimens re- 

 ferred to the following T. troedssoni come from a yellow leached 

 shale at the base of a considerable thickness of dark colored, hence 

 more normal, Athens shale, one and one-half miles northeast of 

 Longview, Ala. With these remains of Telephus occur other simi- 

 larly distorted trilobites — among them Rohergia athenia Butts and 

 undetermined species of Agnostuf^^ Har"pes^ and Ampymnm; also 

 Twrilepas and various brachiopods. Most of these suggest the 

 Whitesburg limestone horizon rather than typical Athens.

Raymond's description is as follows: 



Cranidium small, moderately convex, with broad flaring palpebral lobes which 

 enlarge toward the front. Glabella ovate, tapering considerably toward the 

 front, bearing only one pair of furrows, which are obliquely directed depressions
