BRITISH FOSSILS.

Angelin in the Palseontologia Suecica/' we prefer with Dr. Bey- 

 rich,* to leave the question undecided, and wait for the descriptions 

 and references now in course of publication by M. Angelin. 



Sir K I. Murchison first published it in this country, referring it 

 to Paradoxides, as the only genus then published which it appeared 

 to resemble, especially as he regarded the two lower prongs only as 

 constituting the tail ; he also figured the body rings, and commented 

 on their remarkable rough sculpture; this figure of the body is 

 accidentally reversed upon the plate, the portion nearest the head 

 being turned downwards. 



It is next mentioned by Loven in 1844, describing two of Dalman's 

 species, the G. clavifrons, and G. ornata, and to the latter he referred 

 the figures given by Murchison of the present species. But the 

 comparison could be made only with the body segments, and these 

 are far too much alike in difierent species. The description too of 

 the head given by Loven, though agreeing in the main with the 

 perfect examples we now possess, is not sufficiently precise, and we 

 are not therefore justified in reuniting ours with G. ornata^ more 

 especially so, as the excellent figure of that species lately given by 

 Angelin, Pal. Suecica, p. 21, fig. 1, represents the uppermost or fore- 

 head lobe of the glabella as not wider than the rest, equilata 

 glabella,'' Dalm.), or occupying nearly so much space in length as in 

 our species. 



It is to be regretted that to these descriptions, the author has not 

 added that of G. speciosa ; he does not even mention this disputed 

 species. In 1845, Dr. Beyrich first described the entire animals of 

 this genus, and introduced the British fossil as an undoubted species 

 of Cheirurus, leaving for future observation its identity or other- 

 wise with his G. insignis, to which, as above stated, it bears great 

 resemblance. 



It was again published in the second volume of the Memoirs Geo- 

 logical Survey, 1848, where the head of the species was described and 

 identified with Galymene speciosa of Hisinger. And we still regard 

 Hisinger's excellent figure as a proof that our species is found in 

 Gottland, in a stratum marvellously Hke our own Wenlock lime- 

 stone. In that notice the very large size the species attained was 

 represented, and we accidentally repeated the error of reversing the 

 position of the body ring by turning the front edge downwards. 

 Lastly, Professor M'Coy, in one of his useful contributions to the 

 " Annals of Natural History,'' described the entire animal, which 

 he has since figured in the Synopsis of the Woodw. Mus. fossils, 

 * Untersucli. iiber einige Bohm. TrUob, (1845), 1st part, 1. p. 17, 18.
