tinguishiug feature. As the embryo progresses, however, the oil-globule 
becomes darker aud eventually assumes a brick-red colour, while on the 
embryo, itself the yellow and black pigment-cells become more clearly 
marked. Over the superior region of the yolk a few black branching spots 
are scattered, and there is a network of clear round markings connected by 
lines over the surface of the volk. 
On the 8th all the eggs had hatched out and showed the following 
characteristics : Length about 4'16 mm. and greatest breadth 1"04 mm. The 
position of the rectum is anterior, the notochord is multicolumnar, and the 
oil-globule is situated ventrally, sometimes being anterior and at others 
posterior to the vertical axis of the yolk. Over the whole body and yolk are 
black stellate and yellow branching pigment-cells, and on each of the median 
fins are black branching spots. There are signs of the development of the 
pectoral fins, and the whole of the surface of the yolk aud dorsal and ventral 
fins is covered with a network of clear round markings and lines. 
On the second day after hatching the most noticeable change was that 
many fine branching black cells and a few yellow had spread on to the fins, 
and that the length had increased to 5'05 mm. while the oil-globule had 
apparently decreased in size, being on the third day only about "048 mm. in 
diameter. 
The size of the egg and the colouring of the larva resemble those of 
Trigia Jcumu. The oil-globule, though coloured, is, however, much smaller 
and the newly-hatched larva larger. Besides Trigia humu two other species 
occur in Cape waters, and the eggs and larvae may belong to one of these. 
Species ? 
These eggs were procured during the month of December only, aud then 
in no great numbers. They measure in diameter between "89 and '82 mm., 
and contain a single oil-globule which varies from -18 to '16 mm. in diameter. 
A brownish tinge suffuses the embryo. 
The larva is about 2*1 mm. long, and scattered irregularly over it are 
numerous spots of brown-coloured pigment, the largest of which are situated 
before and behind the eyes, near the otocyst, and over the rectum, while the 
spots on the body branch slightly on to the fins. On the oil-globule, which 
is in a postero- ventral position, are one or two brown spots. The rectum is 
close up to the posterior end of the yolk-sac and the notochord multi- 
columnar. The larvae of this species only lived a few hours. No number 
is attached to this unknown species as distinctiv^e characters are so few.
