Hatching took place on the following day, and the larva 

 showed several distinctive features (^cide Plate V, fig. 36). The 

 colouring matter, a bright brick red, was arranged in the follow- 

 ing manner : Patches on snout, crown, orbit, otocyst, middle of 

 the margin of dorsal fin, along the superior margin of 

 body to near the tail, in the middle of the bod}', yolk (most 

 marked behind oil globule), between yolk and rectum, and on 

 inferior margin of tiie body. The most distinct were the 

 patches above and below the body and extending on to dorsal 

 and ventral fins. These were situated between the yolk and 

 the extremity of the tail, but nearer the former. 



Other characteristic features of the larva, were the tuberculate 

 appearance of the dorsal and ventral fins and their margins. 

 Shght markings, apparently of the same nature, appeared on 

 the posterior region of the yolk, the substance of which was 

 homogeneous. The oil globule, which was situated posteriorly, 

 had a purplish tinge on its periphery. The rectum was anterior. 

 The notochord was mostly unicolumnar. 



The relatively small size of the ^^^ and the characteristics of 

 the larva agree, on the whole, so well with the description and 

 figure of Arjio gloss US'-' that I have little hesitation in provision- 

 ally identifying the parent as Arnoglossus capcnsis, Blgr., a flat 

 fish recently described from False Bay.t 



On 24th November, 1903, an egg was procured in False Bay 

 •7 mm. in diameter and having seven small oil globules in a 

 group and about six branching cells on the yolk near embryo. 

 On the 27th this produced a larva apparently identical with the 

 above. The seven oil globules had fused into one, " 1 1 mm. in 

 diameter. The larva was 2'8 mm. in length, had a few black 

 spots on body and some black branching cells on yolk (not 

 observed in the first specimen). The oil globule had a yellowish 

 tinge, and the general colouring of the body and fins was the same 

 as in the first specimen, witli the same general arrangement. 

 The fins were tuberculate in the same way. 



SPECIES XII. 



On several occasions fish eggs were procured in False Bay 

 in the month of November, having a diameter of '89 mm. with 

 an oil globule of "15 mm. This agrees so closely with the eggs 

 of Chrysophj-ys globiceps {vide Marine Investigations in South
