PLATE LIT, 
3nd the lower part of the back bone near the tail very strangely dis-i 
Ported, is mentioned by Linnteus as being sometimes observed in the 
rivers of Sweden. Pennant records this variety also, stating that it is, 
found in a lake called Llyn Raithlyn in Merionethshire. This variety, 
must be acknowledged candidly, we have never had the opportunity 
of inspecting? but since Dr. Bloch has intimated his suspicions that 
toth Linnaeus and Pennant are mistaken, we must add, that there can 
^0 little doubt of the existence of a variety so distorted, however its 
‘deformity may be occasioned. We are credibly informed by some 
experienced old fishermen in Merionethshire, that it is still found in 
^'^ore than one of the lakes near the Arrenig mountain. 
In the first dorsal fin of our fish there are fifteen spiny rays ; and 
fifteen soft rays in the second dorsal fin: pectoral fin fourteen: 
Central eight : anal twelve : and caudal twenty-onei
