Crustacean Fauna of So^(,th Africa. 115 



Stebbing has already described specimens of this species from 

 Algoa Bav arid remarked upon some of the features in which the 

 South African specimens differ from previous descriptions. These 

 same specimens 1 have re-examined, aud on the whole am able to con- 

 firm Stebbing's remarks. I make, however, certain further observa- 

 tions 011 the sexual differences in the uropods, and as regards the 

 peraeopods I find certain small discrepancies. 



The peduncle and outer ramus of the 1st and 2nd uropods are 

 covered with fairly numerous spines along the upper margins, inner 

 ramus of 1 st uropod with rather fewer spines, inner ramus of 2nd 

 uropod constricted at its distal third, with 1 spine at the constriction 

 and 3 spines nearer base. Third uropod in <- as described by Steb- 

 bing ; in the ? , however, with only 3 setae on distal part of inner 

 margin of outer ramus and 3 small spinules on distal part of outer 

 margin of inner ramus. 



The fringe of setae on 5th and 6th joints (Stebbing, I.e. p. 68, writes 

 "4th and 5th " by a laps, cal.} of 1st gnathopod does not seeni to be 

 present normally ; the 5th joint has 5-6 pairs of setae on hind margin 

 and 2-3 on apex, 6th joint has a row of fine, short and closely-set 

 setules along Avhole hind margin and in addition 6 isolated tufts of 

 setae. The corresponding joints of 2nd gnathopod on the other hand 

 do have a dense fringe of setae. There are no sexual differences in 

 either of the gnathopods. 



Specimens from Simon's Bay in False Bay agree with the Algoa 

 Bay specimens. 



Stebbing has also mentioned a small specimen, presumably from 

 Algoa Bay like the others, with pale eyes, 1st joint of 1st antenna 

 with 2 acute spines, telsonic apices with a small tooth, and other 

 variations. Adult specimens from False Bay have the following 

 characters : 



Pale eyes, acute teeth on 1st peduncular joint of 1st antenna, 

 flagellum 30-jointed, accessory flagellum 7-joiuted, 2nd antenna with 

 flagellum 30-jointed in ? , in g reaching to end of body, 2nd joint of 

 mandibular palp with 1 apical seta, 1st and 2nd guathopods and uropods 

 as above described for the dark-eyed form, with the same sexual differ- 

 ences in the uropods, telson as described by Stebbiug. 



Length: 10 mm.; largest ovigerous $ 13 mm. (light-eyed 

 form). 



Localities: Dark-eyed form : Algoa Bay, 4-16 fathoms (Stebbing) ; 

 Saklanha Bay, 25 fathoms (Chiltou, presumably dark-eyed, but this 

 point not mentioned) ; Table Bay, shore. \, 1 ? . 26/3/96 (Dr.
