It is very much to be regretted that all efforts to discover the original of pl. x, 
vol. ii, 2d series, of the ‘ Transactions of the Geological Society of London,’ have proved 
ineffectual, since there is much reason to believe it belongs to the genus under notice, 
and perhaps to the same species. Although the lithograph is rather indistinct, there is 
yet enough expressed to show the arrangement of the rays of the caudal fin, peculiar to 
Celacanthus. A faimt concentric pattern is also traceable on various parts of the body, 
which is characteristic of the scales in this genus. The specimen represented in 
Pl. XX VIII* is in my own possession. It shows little more of the fish than the figures 
given by Agassiz; but the scales are in a better state of preservation : they are irre- 
gularly rounded, and marked by fine, undulating, concentric lines. The enamel is 
thickly covered with the granulations which suggested the specific name. The second 
dorsal fin is also shown: it seems to have been larger, and the rays thicker than in 
the anal fin opposed to it. The extremity of the tail is dislocated, and is seen in the 
lower part of the plate.—P. G. E. 
Celacanthus granulatus is stated to have been found at Ferry-Hill and Kast Thickley, 
in Marl-slate. The “ Fossil Fish” represented in the ‘ Transactions of the Geological 
Society,’ 2d series, vol. iil, pl. xi, appears to have been found either at Midderidge, or 
East Thickley. 
' The reader is referred to the chapter on the family of the Asterolepis, in Hugh Miller’s interesting 
‘Foot-prints of the Creator,’ pp. 24-37, for the latest researches on this group; and to Agassiz’s ‘ Mono- 
graph of the Fishes of the Old Red Sandstone.’ 
2 Professor Sedgwick, comparing this fish with the other species noticed by him, states, that it 
“differs entirely from all the former, but it is far too imperfect to be referred to any known species or 
genus.” I have in vain endeavoured to obtain a sight of the specimen; but it is now not known where it 
can be seen. ;
