I. — Note on a Collection of Carboniferous Tkilobites from 



THE Banks of the Hodder, near Stonyhurst, Lancashire.

(PLATE XIV.) 



EARLY in 1893, the Rev. G. C. H. Pollen, S.J., of Stonyhurst 

 College, was so kind as to send up to me for examination 

 a collection of Carboniferous fossils, obtained by himself with the 

 assistance of Mr. William van Waterschoot van der Gracht, Jur. 

 Stud., who during his residence at Stonyhurst paid much attention 

 to the geology of the neighbourhood. 



The collection proved to be an extremely interesting one, and 

 Mr. Pollen most kindly requested me to keep a selection of the 

 specimens for the Museum, only returning him a named duplicate 

 collection for Stonyhurst. Subsequently Mr. van der Gracht sent me 

 all the specimens he had himself collected, so that I was able to 

 study a very fair series of the fossils from these beds. 



The specimens sent up were carefully examined by Mr. R. B. 

 Newton, F.G.S., and were found to comprise as follows : — Fragments 

 of Vertebrata (possibly phalangeal bones of a small reptile?), also 

 a part of jaw of a small Fish? (not determined).

My first impression, and that also I find which was entertained by 

 Mr. Pollen, was that we were dealing with beds of the age of the 

 Yoredale series, and this view was confirmed by a reference to 

 the Geological Survey map, upon which the beds along this part 

 of the Hodder are so coloured. 



In the Centenary Record of Stonyhurst College, published in 

 1894, by the Rev. John Gerard, S.J., I am quoted, at p. 278, as 

 having stated that the Trilobites obtained by Mr. Pollen from the 

 banks of the Hodder " represent probably the highest zone in the
