removal from our list. By far the largest number of 

 specimens found in the Deep mine belong to a single species. 

 The remainder belong to four or five species which are 

 probably new to science. The following species have been 

 recognised : 



Palmoniscm Egertoni, Agassiz. (Ref., Brit. Organic 

 Remains, Dec. vi., pi. 11.) This is a small species not 

 more than two and a half inches in length. The body is 

 covered with rhomboidal scales, " characterised by being 

 deeply furrowed and serrated at the posterior margin." 



Position and locality : Goldmine ironstone, Silverdale ; 

 Knowles ironstone, Fenton. 



Palceoniscus Wardi, n. sp., J. Young, M.D. The maximum 

 length of this species is from three to four and a half inches ; 

 its maximum breadth about three quarters of an inch. 

 The body continues of a similar width up to the dorsal 

 and ventral fins : it then contracts to little more than one 

 quarter of its width. The fins are of a moderate size, with the 

 exception of the pectorals, which are very long : these consist 

 of about twenty-four fine, slender rays. The ventrals are 

 about half the length of the pectorals : they consist of from 

 twelve to fourteen fine, delicate rays. The anal fin, in a specimen 

 four inches in length, is two and a half inches from the 

 snout. The number of fin rays is thirty-two. The dorsal 

 fin is placed slightly in advance of the anal, and has the 

 same number of jointed fin-rays. In none of our specimens 

 is the caudal fin well shown. The head is one inch in 

 length, and its breadth is the same as the greatest width of 

 the body ; the snout is blunt and rounded ; the gape mode- 

 rately large ; the jaws are strong and filled with minute sharp- 

 pointed teeth on their outer border, behind which there
