158 Barber .— The Structure of P achy theca. II. 
quarry near Stoke Edith in Herefordshire 1 . A small speci- 
men was turned up by my friend Mr. T. Groom at Ledbury. 
I am indebted to Mr. Jas. Reid of Blairgowrie, who has 
forwarded to me specimens of Pachytheca from the Old Red 
Sandstone of Perthshire 2 . The specimens are rare and 
poorly preserved. 
Of Canadian specimens I have had no means of judging 
excepting from the figures of Sir W. Dawson 3 . I am in- 
clined to regard the fossils in both countries as identical. 
Figures of Pachytheca , exhibiting microscopic structure, 
appear in Rev. J. D. La Touche’s descriptions of Shropshire 
fossils 4 . These figures, I believe, were contributed by Sir J. 
D. Hooker. 
Dr. Grindrod found his specimens in the .West Malvern 
Wenlock Limestone 5 . I have not myself succeeded in ob- 
taining any specimens there. With the permission of Pro- 
fessor A. H. Green, I have examined carefully Dr. Grindrod’s 
collection, now in the possession of Oxford University, but 
I found no trace of Pachytheca from this locality. 
Dr. Hicks has noted Pachytheca in the Denbighshire Grits 
of the Pen-y-glog slate quarry near Corwen 6 . One specimen 
there is, in the Jermyn Street Museum, which exhibits 
structure. This specimen has been figured by Messrs. 
Etheridge and Newton in their appendix to Dr. Hicks’ paper. 
The specimens which I succeeded in knocking out at this 
quarry were small and devoid of structure. My best thanks 
are due to Dr. Hicks for his care in directing me in the 
somewhat difficult search for these fossils. 
The specimens found by Mr. Storrie at Cardiff, in the 
Wenlock rocks of Tymawr quarry, form the subject of the 
present paper.
