The ova and larvae of fish as yet unknown are also 

 described. These, designated Species I-XI, were found in fair 

 abundance in tow nettings, and two (sp. 1 & II) were found in 

 dredging, being attached to shells and rocks. One species (XI ) 

 was procured in the dredge and consisted of a cluster of eggs 

 perhaps demersal. With the exception of these last three 

 all the eggs examined were found to be pelagic or floating 



Only two instances among the teleostean fishes have bi^en 

 found in which the young is brought forth alive. This is the 

 case in two species of Klip-fish (C7/////S :<iip('n'iliosiis and Cliinis 

 C(ipt'iisis).*

The development of this fish m.iy hi; taken to represent a 

 typical example of a free floating egg giving rise to a pelagic 

 larval form. For this reason it is here treated in a little more 

 detail than is necessary for specialistic purposes. 



The fish is one of the commonest of Cape fishes, and is readily 

 procured by the trawl. In November and December abundance 

 of ripe eggs can be got from mature females, but the mature males 

 have alwavs been found in much greater numbers. With some 

 practice the males and females can be readily distinguished as 

 they come on deck, the males being of a somewhat darker 

 steel blue colour than the females. A more definite mark of 

 distinction, which has not yet been found to fail, is that the 

 region between the ventral fins is white in the case of the 

 females and blue in the male. As a rule also the profile of the 

 head region rises much more abruptly from the end of the 

 snout in the male than in the female, and there is usually 

 present in the former a blue patch in this region between the 

 end of the snout and the eyes. 



* Note. — This fact was known for the first-named species as early as the 

 time of Bloch.
