﻿36 MR. E. S. C0BB0LD OX TEILOBITES ER03I [Feb. ICJIO,- 



Anoxnocare, Angelin. 



Mr. Philip Lake, who very kindly examined many of my 

 specimens from Comley, suggested to me that certain of the forms 

 belonged to Angelin's genus. 



The evidence supplied by the fragments next to be described is- 

 too scanty to enable me to be certain whether they should be 

 placed in this genus or with the preceding Agraulos (Strenuella). 

 The fragmentary pygidium [173] (PI. V, fig. 6) is so much 

 mutilated that it is impossible to say whether it had or had not 

 an extended flat border similar to those figured by K. A. Gronwall 

 as belonging to A. excavatum, Ang., and A. Iceve, Ang. 1 



Axomocare plattcephaltjm, sp. nov. (PI. Y & ? PI. IV, fig. 10.)

 1909, p. 236. 



This species is associated in the same rock with Agraulos 

 (Strenuella) salopiensis, and appears to be equally plentiful ; but, 

 owing to the greater flatness of the head-shields, it is perhaps 

 more easily collected, and I have about twelve nearly complete 

 cranidia, as well as a large number of fragments. 



This comparative flatness of the heads has suggested the specific 

 name. 



Craxidiem : Size. — Length varying from 4 to 8 millimetres. 



General form. — Subquadrangular, with broadly rounded front. 



General convexity. — About -L- ; while the convexity is not 

 inconsiderable, there is an absence of relief in the separate features 

 which gives an idea of flat-headedness to this species. 



Glabella. — Convex ; almost parallel-sided ; apex rounded semi- 

 circularly ; strongly impressed at the sides by three pairs of 

 glabellar furrows which are wide and ill-defined. The posterior 

 furrows are always, the median frequently and the anterior some- 

 times, inclined backwards, and they all penetrate into the glabella 

 for a third or more of its width, and in so doing constrict the 

 median portion, giving it a somewhat carinate appearance. The 

 inner ends of the posterior pairs are often wider than the outer, 

 as though the furrow had been impressed first in one direction 

 and then in another. In one specimen [142] the furrows are much 

 widened, and their outlines blurred (PI. Y, fig. 2). 



Occipital furrow. — Strongly impressed at the sides, but 

 hardly traceable across the median third, where it seems partly 

 invaded by a thickening of the occipital ring. 



Occipital ring. — Expanded in the middle, both forwards and 

 backwards ; the surface is but slightly convex longitudinally and 

 inclined backwards ; in some instances, there is a slight depression 

 across the centre parallel to the lower border. Occasionally, a very 

 minute tubercle is visible (with a strong lens) on the axial line.
