BRITISH FOSSILS. 



Pamdoxides Davidis nearly equals in dimensions the great 

 P. Rarlani from Massacliusetts, and exceeds the large Newfound- 

 land species described by me under the name of P. Bennettii* 

 The three Swedish species are greatly inferior in size. 



The above description is chiefly taken from the Quarterly Geol. 

 Journal for the present year. In the plate accompanying that 

 Memoir all the varieties are figured. 



Locality and Geological Position. — Lowest Lingula Flags, 

 Forth Rhaw and Solva. Harbour, both near St. David's, South 

 Wales. It has been lately detected at the Dolgelly gold mines, close 

 to Pistyl-y-Cain, by Mr. Readwin, and by Mr. Ezekiel Williamson, 

 an excellent observer.

Description.— Our specimen must, when perfect, have been fully 

 3^ inches long by 1^ broad. Of this length the long head is fully 

 one inch, semi-oval, and with a long clavate glabella, which reaches 

 quite to the front, and is rather broader than the cheeks. Below, 

 the glabella is sub-linear, and not much above half as wide as in 

 front. And it appears to have only the two lower complete trans- 

 verse furrows ; the upper inflated portion, more than twice the 

 length of the lower, being unmarked by any furrows, except a pair 

 of very short ones marking the place of the middle lobes. f The 

 eye is larger and placed further back on the cheek. The border of 

 the head distinct and broad. Spines — ? (the outer angle of the 

 cheek is lost, and we do not know what the spines may be). 



Body with a long cylindrical axis tapering very slowly back- 

 wards, with straight sides. The axis-rings are not, even in the 

 front part, more than thrice as wide as long, and at the twelfth 

 ring not so much. We have only 15 of the body segments, 

 and the pleurae are equal and similar for the first eight rings at

f Two pairs are marked out in the figure in Siluria above quoted. But there is hardly 

 any warrant for this. The specimen is too imperfect to decide it fully.
