but slightly produced. Pleon segment 3 with postero-inferior angle broadly rounded, 

 obscurely serrulate. Telson, lateral margins 

 slightly concave beyond the basal convexity, 

 cleft for almost half its length, lobes apically 

 subacute with a single spine in a notch. 



Antenna 1 , flagellum with sensory filaments 

 on every alternate joint. 



Gnathopods 1 and 2, 5th joint shorter than 

 6th, not strongly lobed below, 6th widening 

 to the nearly transverse palm, which has three 

 to four spines on the rounded defining angle. 



Remarks. The integument, gnathopods and 

 telson prevent this form from being regarded 

 as the same as the young specimen hesitatingly 

 identified by Monod (1926) as P. aiistrina. 



Paramoera tristanensis, n.sp. (Figs. 118 k, 127). 



Occurrence: 1. St. 6. Tristan da Cunha. 6 $$ and 4 ovig. $$ 6-7 mm. Types. 

 2. St. WS 123. Gough Island. 5 ovig. $$ 7-9 mm. (shore). 



Description. Integument minutely shagreened, with rather numerous pits, closer 

 together than in obliquimanus and not as 

 large as in gregaria. No dorsal teeth. Post- 

 antennal angle of head quadrate. Eyes oblong, 

 slightly larger in 6* than in ?. Side-plates 1 

 and 2 rounded below. Pleon segment 3 

 with postero-inferior angle broadly rounded, 

 margin obscurely crenulate or serrulate. 

 Telson half as long again as wide, cleft for 

 about three-quarters its length, lateral mar- 

 gins convex, lobes slightly dehiscent, apices 

 subacute, each with a single spine. d

Gnathopods 1 and 2, 5th joint rather short, subtriangular, 6th considerably longer 

 than 5th, oblong-ovate, palm oblique, defined only by four spines.
