Reproduction of Fishes in Table Bay.

Onos capensis, Kaup. (PI. I, figs. 14, 15 and 16 ; PI. II, fig. 17.) 
The eggs of this fish were procured in the tow- nets during every month 
of the year, but were most plentiful during August and September ; in these 
months also the advanced larval stages were procured and an adult form. 
The egg is small, its diameter varying from "78 to '72 mm., and is dis- 
tinguishable by its greenish-yellow oil-globule, which varies from "14 to 
•16 mm. and has black stellate pigment- spots. A small percentage of these 
eggs have, in the early stages, two or three oil-globules, which, however, 
usually fuse into one before hatching takes place. Over the embryo are 
numerous black pigment-cells. 
The larva is about 1*75 mm. in length, and over the head and body to 
within '48 mm. of the extremity of the tail are many black pigment-spots, a 
particularly dense mass of these in a branching condition occurring about 
midway between anus and tail. On the oil-globule, which is situated in a 
posterior position, are several black stellate spots. The rectum is situated 
anteriorly and the notochord is multicolumnar. The pectoral fins are fairly 
well developed, and the dorsal and anal fins, which are not very deep, are 
devoid of pigment. The yolk is homogeneous. 
The larvae were reared to the seventh day, but no marked change occurred 
after the second day, when the chromatophores opened and spread over the 
greater portion of the body. 
Of the larval forms procured in the tow-nets the smallest was 2*9 mm. 
in length and the largest 15 8 mm. The most characteristic feature in all 
these stages is the development of the ventral fins. In the smaller forms 
they are elongated and fan-shaped, with four projecting rays, and are deeply 
pigmented with red and black. In the larger forms they become more 
elongate, and are pigmented only in their posterior half. In all, except the 
smallest forms, they were about one- third of bhe body in length. 
In the larger forms a green margin traverses the animal from head to 
tail on each side of the dorsal fin, the rest of the animal being black, with 
the exception of a few yellow stellate spots on the head. 
This is one of the few cases in which it has been possible to identify the 
egg by finding all stages in the tow-nettings up to the adult form. 
Pleuronectidae. 
Synaptura microlepis, Blkr. (PI. II, figs. 18, 19.) 
Certain eggs believed to be those of Synaptura microlepis were found 
near St. Helena Bay (* Mar. Biol. Eep.,' no. i, p. 82). They closely resemble 
the known eggs of S. pectoralis, but as this species does not occur on the 
West Coast it was presumed that they were the eggs of 8. microlepis. 
Similar eggs have been found in the nettings in Table Bay. They were
