CCEL ACANTHUS ELONGATUS. 25 



This Ccelacantb appears to have attained much lax*ger dimensions, 

 as a fragmentary specimen from the same locality has neural 

 arches 0*45 in. long, whilst those of the example described nowhere 

 reach 0\2 inches. 



A fragment of a caudal extremity of a Ccelacanth, in the same 

 collection, leads me to suspect that a second, deeper and shorter 

 bodied, species may have coexisted with this. 



Numerous specimens sent to me by Prof. Jukes demonstrate 

 the existence of a true Ccelacanthus in the Coal measures of Bally- 

 bunuion, Kerry. The largest impressions belong to fish about 12 

 inches long, and the fossils vary from this size to less than six 

 inches. In none are the scales or the form of the head preserved, 

 and hence I can give no strong opinion as to the specific dis- 

 tinctness of this Coelacanth, or its identity with other species. I 

 am inclined to think, however, that it is rather more slender than 

 C. lepturus.
