Reproduction of Fishes in Table Bay.

Triglidae. 
Trigla kumu, Less. (PI. I, figs. 1 and 2 ; PI. I, fig. 3.) 
The eggs of the Eed G-urnard were obtained from the end of August to 
the end of December, being most abundant in October. The egg and larvae 
are readily recognised, and are not very different from those of the common 
Gurnard of the northern hemisphere. 
The eggs and larvae of this fish have already been described (' Mar. Inv.,' 
vol. ii, p. 190, PI. I, fig. 14). Those procured in Table Bay show that the 
egg varies in diameter from 1"25 mm. to 1*05 mm., those previously procured 
in False Bay from the living fish having been recorded as from 1"21 to 
1-07 mm. The oil-globule varied from -24 to "23 mm., those from the living 
fish being uniformly "23 mm. In the Table Bay specimens it was noted 
that the oil- globule was of a yellow colour with dark margin. This yellow 
colour was not noted in the original description, but there can be little 
doubt from the characteristics of the egg and particularly of the larva that 
this is the Gurnard. The colour of the oil- globule has been found to vary 
or be entirely absent in European G-urnards. The larva from the Table 
Bay eggs was reared to a later stage than those of the False Bay eggs and 
has a dark pigmented border to the large pectoral fins. The length of the 
newly-hatched larva was 3 -3 mm. 
The original description of the egg and larva of Trigla hunm was written 
in 1904, and it is of interest to compare it with a subsequent account of the 
egg and larva of what appears to be the same species in New Zealand 
(Anderton in ' Trans. New Zealand Institute,' vol. xxxix, p. 478, 1907). The 
egg of the New Zealand Trigla Jcumu is given as 1*7 mm. in diameter; 
there is a single " large " oil-globule, which, calculated from the dimensions 
in the figures, appears to vary from about '22 to "18 mm. ; this oil-globule 
was of a bright orange colour. The egg of the Cape Gurnard, therefore, 
is "45 mm. smaller than that of the New Zealand species, and the oil- globule, 
though about the same size, has less marked colour. 
The larvae in both cases have similar markings, consisting of black and 
yellow chromatophores, which extend on to the fins. The size of the larva 
of the New Zealand Gurnard is, like that of the egg, somewhat greater 
than that of the Cape species, being about 4 mm. as against 3*31 mm. 
These differences, however, are not very much greater than have been 
observed in the case of the European Trigla gurnardus, whose eggs have 
been found to vary from 1*63 to 1*16 mm. in diameter and the newly- 
hatched larva from 3 to 4 mm. in length. 
Agriopus spinifer, Smith. (PI. I, fig. 4 ; PI. II, fig. 5.) 
One of the most unexpected results of the tow- nettings in Table Bay was 
the great number of large eggs, which correspond in size and other charac- 
teristics to those already described as belonging to Agriopus spinifer. They
