This sole is apparently confined almost exclusively to 

 fairly shallow water. Specimens were procured from Fish 

 Hoek and Muizenberg (in False Bay) by seine net. No 

 specimen has been procured in the frequent trawling opera- 

 tions of the Government vessel in this locality, nor to my 

 knowledge in the subsequent trawling operations of other 

 vessels. One specimen only has been procured by the 

 Government steamer, 4^ miles oflf Cape St. Blaize, in 30 

 fathoms (mud). It was in a much poorer condition than 

 those caught in the shallow waters of False Bay. Two 

 specimens, said to have been found in Algoa Bay, were 

 procured from the Port Flizabeth Museum. 



Length, 338 mm. (including caudal). 



BRANCHIOSTOMA CAPENSE, n.sp. 

 (Plate X.) 



Myotomes 47 + 19 + 9. Length 30 to 48 mm. Dorsal fin 

 low, rays commencing over first myotome, attains its greatest 

 height a little in front of the vertical from the anus and in 

 several specimens shows the characteristic lancet shape of 

 B. laficeolattun, but in others this is not so marked ; about the 

 middle of the body its height is 7^ in that of body. The 

 anal fin is somewhat deeper than the dorsal and extends from 

 the posterior extremity of the body to the atrial opening, the 

 border being uninterrupted with no trace of the lancet-shaped 

 outline as in the dorsal ; it is not continuous with either of 

 the metapleural folds and has fin rays at its base. The oral 

 cirri are 36 in all ; the basal pieces forming a ring which is 

 interrupted at the upper part where the last segment on each 

 side bears four very small cirri ; the anterior part of the ring 

 falls under the second myotome. The cirri are connected by 

 a low membrane to about -I of their length. The dorsa) fin 

 after passing over the anterior extremity runs along the 

 ventral side into the right buccal fold, the origin of the left 

 buccal fold being thus not in the median line, but on the left 

 side. 



There appears to be no pigmented spot or " eye " in front 

 of the nerve chord, but there is a series of very distinct black 

 spots running along the top of the chord, beginning from 

 about the 3rd segment and extending to near the posterior 

 end. This line of spots appears broken up roughly into 

 groups, there being a tendency to aggregate at each muscular 

 segment. 



In a specimen examined by staining and mounting in 

 balsam there were 30 gonads on the left side, the first in the 

 18th segment, the last in the 47th. A similar number was 

 found on the right side.
