Crustacean Fauna of South Africa. 169 



First auteuna reaching to end of peduncle of 2nd antenna, 1st joint 

 stout, 2nd not quite as long as 1st, 3rd not quite i 1st but more than 

 ^ 2nd, flagellum equal to 2nd and 3rd joints together, 8-jointed, acces- 

 sory flagellum 1 -jointed, reaching to middle of 2nd flagellar joint, 

 apex setose. 



Second antenna, inferior apex of 2nd joint reaching to middle of 

 3rd joint, 4th joint longer than 5th, flagellum equal to 3rd and 4th 

 joints together, 6- jointed. 



Upper lip rounded as in B. australis Stebbing. 



Lower lip, outer lobes distinct, from mandibular processes as in 

 B, australis. 



Mandible, 3rd joint of palp shorter than 1st. 



First maxilla, inner plate with 10 setae, outer plate with 11 spines, 

 apex of 2nd joint of palp with 5 spinules and a smaller one on outer 

 distal margin. 



First and second gnathopods, palm denned by one simple spine and 

 one denticulate spine (as in other species). 



First and second peraeopods without particular features. 



Third to fifth peraeopods, 2nd joint narrow oblong as in B. typica, 

 hind margin serrate but not so strongly as in B. australis, postero- 

 inferior angle in all three peraeopods rounded. 



First uropod, outer ramus f length of inner, upper margins of both 

 ranii very finely serrulate, that of outer ranius in addition with 3 small 

 spinules. 



Second uropod, outer ramus a little more than length of inner, 

 margins unarmed. 



Third uropod, rarni subequal, but inner ranius broader, margins 

 unarmed . 



Length : 7 mm. 



Colour : In spirit, whitish. 



Locality : Cape Point N.E. by E., distant 36 miles. 650 fathoms.

The specific name refers to the teeth on 7th peraeon and 1st pleon 

 segments. 



This is the fourth species of the genus. It appears that a strongly 

 carinate dorsum is correlated with an acuminate rostrum, and a feeblv 

 carinate dorsum with a blunt rostrum. The two North Atlantic 

 species, B. tuberculata G. 0. Sars and B. typica Boeck, respectively 

 show these characters. B. australis Stebbing from New South Wales 

 corresponds with the first, while the South African species corresponds 

 with the second form.
