not forked but single, small and inclined backwards ; further 
(3), the series of plates between the ventral and anal are not 
provided with points. Zeus Capensis is also described as hav- 
ing one ray less in the soft anal. 
Smit (Scandinavian Fishes, p. 308) refers also to the difference 
between Zeus faber and Zeus capensis as ‘‘ extremely slight,”’ 
and adds : “‘ The latter may perhaps deserve a distinct specific 
name as the form marked by an increase in the number of 
spinous plates.’’ The following table drawn up on an examina- 
tion of eleven specimens of Z. capensis varying from adults to 
quite small forms will show more clearly to what extent the 
two species differ :—

From an examination of this table it will be seen that, on 
the whole, there is in Z. capensis a larger number of spinous 
plates at the base of both the soft dorsal and anal; the forked 
spines, said to be characteristic of Z. faber, are found only in 
the smaller forms, indistinctly in some but very distinct in the 
smallest. The difference between the South African and 
European species, said to be indicated by the presence or
