32 ANNALS OF SCOTTISH NATURAL HISTORY 



* 

 this was long considered as a reptile of the Old Red Sand- 

 stone period, though the affinities of the ever increasing series 

 of reptilian remains which have been since discovered in these 

 beds have in recent times determined their age to be, in all 

 probability, Triassic. 



One carboniferous fossil, or rather pair of fossils, in the 

 Powrie collection is also worthy of notice, namely two of the 

 original specimens of Eurypterus Scouleri, from Kirkton near 

 Bathgate, figured by Hibbert in 1835 in his celebrated 

 " Memoir on the Burdiehouse Limestone." I am not aware of 

 any specimens of this remarkable creature having been found 

 since Hibbert's time. 



As all working Naturalists, whether they busy themselves 

 with things recent or fossil, are aware of the importance 

 of knowing the whereabouts of original specimens of which 

 descriptions or figures have been published, I have thought 

 that a list of those contained in the " Powrie Collection," all of 

 which are Scottish fossils, might form an appropriate con- 

 tribution to the first number of the " Annals of Scottish 

 Natural History." 



In all cases the first name given is that which was applied 

 to the specimen in the work in which it was described or 

 figured. Corrections or rectifications of nomenclature come 

 afterwards. 



I. Specimens Constituting Original Types upon 

 which Species have been Founded. 



SILURIAN. 



Merostomata — 



Stylonurus Logani, H. Woodward. — Imperfect specimen from 

 Logan Water, Lesmahagow. H. Woodward in " Geol. Mag." 

 vol. i. (1864), p. 197, Plate X. Fig. 1. The counterpart of 

 this specimen, belonging to the Museum of Practical Geology, 

 is figured in "British Fossil Merostomata," Plate XXIV. Fig. 1. 



OLD RED SANDSTONE. 



Merostomata — 



Eurypterus Brewsteri, H. Woodward. — Carapace from Kelly Den, 

 near Arbroath, described and figured by H. Woodward, 

 "Geol. Mag." vol. i. (1864), p. 200, Plate X. Fig. 3, and in 

 "Brit. Foss. Merost.," p. 151, Plate XXVIII. Fig. 4/
