nutocliord nuillicoluninar. The lon,<4 body is somewhat dark,,, 

 and a few small black stellate cells appear on its ventral mars^in 

 near the end of the tail. In the abdominal region the remains of 

 the blue volk occupy only about half the abdominal cavity, the 

 rest being filled up with the well developed intestine. Above 

 the intestinal mass is a tract of very dark blue pigment. There 

 is a large transparent pectoral hn extendnig upwards l-)e3'ond 

 the dorsal margin of the body by about ^ its length.* The 

 beginning of the dorsal* is situated behind the otocyst, being 

 separated from it by a space about equal to its diameter. The 

 otocvst is verv close to the eye. 



The absence of pigment readily distinguishes it from 

 Species I, and a reference to the figures will show marked 

 differences in other respects, as for instance the anterior posi 

 tion of the anus. 



SPECIES III. 



(PELAGIC.) 



About lialf-a-dozen unknown pelagic eggs were procured on 

 the 2oth November, IQ02, in a surface tow net in False Bay. 

 Thev were very large (17 mm. in diameter), due cliiefiy to the 

 size of tlie perivitteline space, which was in breadth about ;'; the 

 diameter of the yolk. The margin of the egg had a vivid 

 green tint. One oil globule was present, relatively small, being 

 only '2 mm. in diameter. The embryo shows a series of 

 small black stellate spots along the body from head to tail. 

 There are no pigment spots yellow by reflected light. The upper 

 part of the volk next the embrvo has a munber of fine circular 

 lines throughout its substance. (Plate III., figs. 23 and 24.) 



Some were hatched out on the following day. The larva can 

 be distinguished from others by the very elongated body 

 (4*1 mm.). Its movements are also characteristic. Instead of 

 the sliarp wriggle of the tail there is a comparatively slow 

 luidulation of the whole bodv. Though there are no yellow 

 pigment spots, bv refiected light a golden tinge is apparent on 

 the upper margin of the bodv in the region of the otocyst, and 

 on the posterior margin of tiie yolk. Tliere are minute black 

 dots on the upper part of the head, and these extend backwards 

 along the dorsal region of the body to about the vertical from 

 the middle of the yolk, where also the dorsal fin commences 

 A few other dark spots occur here and there on the body. 

 The oil globule is slightly in front of the posterior angle of 

 the volk. The notochord is unicolumnar and the anus is 

 situated in the posterior third of the body, ''PI. III. fig. 25).
