basal third of the iniior ramus is, however, smooth and ahiiost 

 glabrous. 



The external distal tliird of the outer ramus is armed with 

 about ei<i;hteen oval rasp-like teeth ; there is also a row of fifteen 

 occupying more than half of the outer distal marf;;in of the inner 

 ramus. The inner angle of the protopodite is produced into a 

 strong spine. The lateral margins of the telson are slightly 

 thickened, smooth, with a few short seise ; the distal mai'gin is

 Station 57. 



Carapace 7 mm. long and 5 mm. broad, smooth, glossy, slightly 

 uneven and transversely convex, clothed with a few scattered 

 tufts of short setse, posterior region 

 imperfectly calcified. Frontal 

 margin smooth, a little thickened, 

 with two wide semicircular emar- 

 ginations and three prominent 

 denticles ; the lateral teeth are 

 acute and directed forwards ; the 

 straight outer margin measures 

 0"6 mm. and the base 0"4 mm. ; the 

 rostral tooth is 1 mm. wide at the 

 base and 9 mm. long; it is 

 abruptly narrowed at its distal 

 third and subacute at the apex. 



The sides of the carapace bear 

 two spines ; the first is situated 

 on the anterior surface of a rounded eminence, and is about its 

 own length from the base of the external frontal tooth. The 

 second spine is smaller than the first and arises from the anterior 



Carapace x 6.
