WELLBURN : FOSSIL FISH FOUND IN THE MILLSTONE GRITS. 399 
informs me that they comprise portions of the " trunk, showing- 
scales," and portions of the "head, showing cranial bones." 
The specimen found at Eccup, near Leeds, shows a mass of 
scales on both sides of the slab, and probably represents the central 
portion of the body. The ornamentation on the scales is beautifully 
shown, and consists of prominent oblique ridges occasionally 
branching and anastomosing, or where two diverge another being 
intercalated between them. The interlocking of the scales is also 
very well shown, the anterior superior border being produced upwards 
in a very striking manner ; the outer surface of this projection 
and the spine articulating with the inferior and anterior portions 
of the inner surface of the scale above, producing a very firm 
and powerful union. 
Note. — Besides the above, Mr. Aitken mentions the follow- 
ing : — 
1. Ctenacanthus hyhoides ? Tooth of. 
2. Rhizodus Hihherti ? Spine of ? 
3. PalfP07iiscus, Scales of. 
The first seems to have been a tooth of Cladodus sp. ? but 
of the others I can ofier no opinion, as I cannot trace the 
specimens.
