OF THE CULM OF DEVON.

which it approaches, but in Richter's figure the glabella is narrow in front 

 and broader behind, whereas our Culm form is just the reverse. Prof. A. 

 von Koenen, p. 312, op. cit., places Richter's P. posthumus with Phillipsia 

 cequalis, H. von Meyer, and observes, "As von Meyer expressly says that the 

 glabella is reduced in front, there is no doubt that Burmeister was in error in 

 figuring as this species a form with a club-shaped glabella. Emmrich's restored 

 figure does not give a good representation of the species ; the head-shield is too 

 long, the eyes placed too far in front, and the glabella too slightly reduced in 

 front. The form placed by Roemer under Phillipsia latispinosa, from the Silesian 

 Culm of Bantsch appears to me, on account of the very wide glabella, to belong to 

 P. cequalis. Near Nehden I have found an example of which the tail is 15 mm. 

 wide and 10 mm. long, and fragments of still larger dimensions occur at Aprath " 

 (op. cit., p. 313). 



We figure here a specimen of Culm with two compressed Trilobites thereon 

 referred to Phillipsia, which were obtained at Aprath by Mr. J. B. Lee, F.G.S., of 

 Torquay ; but the cheek-spines are wanting in both, although the eyes can be 

 discerned with a high power, and there are faint traces on one of the obliquely 

 transverse furrows on the glabella. A reference to Cylindraspis latispinosa, of 

 Sandberger (taf . iii, fig. 4 and 4 a) shows that the glabella of this species is also 

 more pointed in front than in our British species ; the facial suture is close to the 

 glabella, as in other Phillipsice.

We ought to add that von Meyer's figure of ? Galymene (Phillipsia) cequalis 

 ('Nova Acta,' vol. 15, 2 s. f p. 100, Taf. 56, fig. 13) has no cheek-spines and no 

 eyes, nor are any sutures shown in the head-shield.
