Though the usual dark oil globule was absent, about half-a- 

 dozen very faint clear oily looking bodies were seen indis- 

 tinctly in the yolk. There was no trace of a pectoral fin 

 visible. The growth of the pectoral may be very rapid, as a 

 very similar larva recently hatched from an unknown egg had 

 the pectorals well developed. It is possible also that this larva 

 may bj the same, only hatched out at a later stage of develop- 

 ment. 



SPECIES VI. 



(PELAGIC) 



An unknown larva, apparcntlv newly hatched, was pro- 

 cured in a tow netting on the 12th December, 1902, in False 

 Bay, 5 fathoms from the surface. It was 2-1 mm. in length, 

 and possessed a single oil globule •16 mm. in diameter and 

 situated anteriorly. The volk sac was rather long and oval. 

 Along the dorsal region of the body were small black stellate 

 pigment spots. Yellow spots, very faint, giving only a yellow 

 tinge to the body occurred from posterior of the yolk sac 

 towards the caudal extremitv where no pigment occurs. A 

 yellow patch occurred before and one behind the head. The 

 oil globule is covered with yellow network of pigment. It is 

 probable that this larva was from an egg "81 mm. in diameter, 

 though 1 have some slight doubt as to this, on account of the 

 presence of other unknown eggs. (PI. Ill, tig. 28). 



SPECIES VII. 



^PELAGIC.) 



/ 



An egg i'32 mm. in diameter, and containing many small oil 

 globules, was found in a tow-netting from False Bay on the 

 i6th December, 1902. Hatching occurred the following day. 



The larva, including yolk sac, is covered with yellow 

 branching pigment cells from snout to tail. A few black spots 

 occur on the top of the head and on the mid region of body. 

 The notiKMu)rd is multicolumnar. The oil globules are scattered 

 throughout yolk. There are about 50 of them, and thev vary 

 from -oi to -06 mm. in diameter. The pigment cells on dorsal 

 and anal fins have a tufted appearance. In addition to these 

 distinctive features the larva has a very characteristic pro- 

 trusion over the head region. This, however, seems to vary, 

 as larvae otherwise similar had this feature in a less marked 

 degree. PI. W, fig. 29, is from a photograph of this larva. 

 Another larva, very siinilar in appearance, but with the oil 

 globules situated in a cluster posteriorly may belong to tlie same 

 species (fig. 30) ; Fig. 31 is a later stage of the'latter,
