[Plate XXII.] 



At the meeting of the British Association which took place last 

 September, at Birmingham, the Rev. P. B. Brodie called attention 

 to some specimens of fishes which he had obtained from the Upper 

 Keuper of Shrewley. The specimens, which he has kindly sent to 

 me for examination, are, unfortunately, very fragmentary, but still 

 many of their characters can be deciphered ; and seeing that 

 Ganoid fish-remains from these deposits are of such rare occurrence, 

 it is very desirable to place on record any fresh evidence which 

 may be brought to light. Portions of seven specimens have been 

 found, the best preserved (PI. XXII. fig. 1) showing the left side of 

 the body, minus the head and nearly the whole of the tail, but with 

 parts of the dorsal, pectoral, ventral, and anal fins preserved in situ, 

 with one or two rays of the tail-fin. In its present condition the 

 specimen measures one inch and a half in length. 



The second specimen (fig. 2) seems to include the whole of a fish ; 

 but it is so curved round, twisted, and crushed, that its form is 

 well-nigh obliterated. When perfect, it probably measured two 

 inches and a half in length. The large fulcra of the tail-fin are 

 well seen from above ; but with the exception of one or two 

 plates, probably belonging to the head, little of the structure can 

 be made out. 



The third specimen (fig. 3) appears to be a head with the right 

 pectoral fin and a portion of the body ; but none of the bones of 

 the head are preserved, and there is merely an outline in the form 

 of a head in front of the pectoral arch. Two other fins are pre- 

 served on this block of stone, but they seem to be parts of another 

 fish. The fourth specimen is a portion of a body with the ventral 

 fin (fig. 4) preserved. 



The fifth and sixth specimens (figs. 5, 6) are portions of tails. 

 The seventh specimen, now in the British Museum, is a body with 

 perhaps a fragment of the head, but without any tail or fins. The 

 scales, in the middle of the side, have their hinder margins denticu- 

 lated (fig. 7). 



So far as preserved, these specimens are much alike, and there is 

 nothing to lead to the supposition that they belong to more than 

 one species. Judging from the best specimen (fig. 1) the body is 

 comparatively deep, its entire length, when perfect, being only 

 about two and a half times the depth. At the front part of this 

 specimen there is a curved fragment, which seems to be part of the 

 pectoral arch, and a little behind this there are traces of the 

 pectoral fin. The form of this fin, however, is better shown in 

 another specimen (fig. 3). If the lower margin of this specimen 

 (fig. 1) be divided into three equal parts, then at the junction of
