head and back dark steel-blue, mingled with oil-green ; sides 
beneath the lateral line greyish- white, on silvery ground ; cheeks, 
lower jaw, belly, and ventral fin, white. Fins greyish-green. 
Body crossed by nine narrow longitudinal lines. Interior of 
mouth pure white. Iris silvery. Length fourteen inches ; 
breadth nearly four inches. 
This species, as well as the following, enters the month of several 
rivers. Nursed in ponds, it grows extremely fat, and attains an un- 
common size. A specimen so fed measnred nineteen inches. 
35. Mugil Mutilineatus. A. Smith. (?) [Springer Leap- 
ing Mullet.) — Greatly resembling the former, but easily dis- 
tinguishable ; its head being neither so broad nor flat, but ra- 
ther a little convex on its top. Lower jaw more rounded, and 
body traversed by thirteen longitudinal narrow stripes. Colour 
of back and upper side greenish-brown ; crown of head faint 
purple with oil-green. Gill covers tinted with gold ; ventral 
fin purplish. Lower part of belly greyish- white, on a silvery 
base. Length twelve inches. It is in the habit of leaping con- 
stantly and with considerable velocity, when it finds itself 
entangled in a net; and hence its name. 
Besides the two kinds of Mullet here described, there are three or 
four more species recorded as inhabitants of the bays and rivers of the 
Colony. All of them are caught with the net. They make good 
table-fish, but are more frequently salted or smoke-dried (Aokkoma) . 
like the Herring, and, thus preserved, form a very considerable article 
of home consumption as well as of export. 
BLENNIDvE. 
36. Blennius Versicolor. Mihi. N. Sp. (Klipvisch.) Body 
elongated, smooth, slimy, spindle-shaped ; head thick, obtuse 
forehead tapering towards the snout. Muzzle short, truncate ; 
mouth small ; lips fleshy ; teeth in several rows ; those of the 
first, strong, pointed, conic, hooked ; inner ones small, paved. 
Dorsal fin nearly as long as the body, commencing right over 
the crown of the head ; its first three rays longest, spiny, sepa- 
rated from the soft ones by a deep emargination. Ventral 
placed before the pectoral fins, and consists of only two rays. 
A small tentaculary, three-fid appendage above each eye-brow ; 
and a tubercular excrescence near the anus, in both sexes. It 
is ovoviviparous. No fish perhaps displays a greater diversity 
of hues, than this, and to make out any specific difference 
amongst its many varieties, is next to impossible, I am thus 
inclined to unite them under one common denomination, expres- 
sive at once, of the changeable character of their colours. The 
following are the chief varieties observed by me in fresh 
specimens.
