Mediterranean and eastern Atlantic to South Africa and Natal. 

 Although Barnard retains Charar cervinus Lowe as distinct following 

 Giintlier largely on the basis of 12 upper and 8 lower incisors, Giinther 

 discussed the conflicting characters set down by Lowe and Valen- 

 ciennes, which appear largely inaccuracies, so that probably the names 

 involved reaUy apply to the Mediterranean species, first noticed by 



Rafinesque.
