The fishes, as well as the reptile, are now preserved in the McGregor 
Museum, Kimberley. 
ACROLEPIS ADDAMSI, Sp. n. 
(Plate XX.) 
This species is founded on a number of fragmentary fishes crushed 
together on a small slab of shaly sandstone found in Wesselton Mine on 
the 135 ft. level. 
Though of the five fishes four are almost certainly the same species, 
to avoid any possible confusion the largest specimen will be regarded as 
the type. 
Though it is impossible to ascertain the length of the species, we may, 
I think, safely assume that it was half as large again as the type of 
Acrolejjis ortholepis, Traquair, figured by Traquair, and further that the 
body was relatively deeper. 
The dorsal fin consists of about 32 rays, all jointed, and the posterior 
ones at least branched distally. 
The pectoral and pelvic fins are only seen on a smaller specimen, which 
may possibly not be the same species, and to avoid confusion I think it 
better to leave out the description. 
The anal fin is very large and powerful and has about 55 rays. All 
are jointed and mostly bifurcated. 
The caudal fin is large and bifurcated, but not very deeply. The rays 
are very numerous and distally branched. Fulcra are present along the 
lower border. A series of long narrow median scales form the upper 
ridge. 
The scales of the middle of the body have a series of flat ridges passing 
obliquely backwards and anastomosing. The posterior border of the scales 
is denticulated with about 6 or 7 blunt serrations. The scales are quite 
unlike that figured by Smith Woodward as the type of Acrolepis digitata. 
I have pleasure in dedicating this species to Mr. C. E. Addams, 
sometime manager of Wesselton Mine. 
DiSICHTHYS KIMBEELEYENSIS, g. et Sp. n. 
(Plate XXI.) 
The type of this new geaus and species is one of 6 or 7 fossil fishes on 
a slab of soft sandstone found in the De Beers Mine tip. 
The fishes represent three different species, of which two are sufficiently 
well preserved for description. Both are very distinct new types, and 
must be placed, in my opinion, in new genera.
