PARAMPHITHOIDAE I75 



Uropod 2, outer ramus a little over half length of inner. 

 One inter-antennal tubercle. 



The embryos (no. 9) are 5-5 mm. in length, and the 2nd joints of peraeopods 3-5 are 

 of the inermis or tuber cidata shape. The back is feebly carinate. 



Remarks. Although closely related to inermis and robusta, this species is easily dis- 

 tinguished by the diagnostic characters here described and figured. Though size is not 

 distinctive, it seems to be a larger species than inermis. When the animal is curled up, 

 the manner in which the overlapping 2nd joints of peraeopods 3-5 fill in and protect 

 the space between the 4th side-plate and the pleura of the pleon segments is very neat. 



The embryos of no. 9, and the young individuals of no. 4 are interesting as showing 

 the progressive enlargement of the basal tooth on the 2nd joints of peraeopods 3 and 4, 

 the shifting of the point of divergence of the outer and inner keels further towards the 

 apex of the joint, the expansion on the same joint of peraeopod 5 and its extension distal- 

 wards. As regards the shape of these joints, excisipes when first hatched resembles inermis 

 but diverges more and more as it grows. The 4th side-plate is distinctive right from the 

 earliest stage. 



The colour of nos. 1, 2 and 9 respectively are given as: "Rose-red with red eyes", 

 "heavily mottled with red on a creamy ground. Eyes bright pink", and "Variously 

 mottled with milk-white on a bright red or crimson background. Some specimens 

 mainly white, others mainly red. Eyes shining red". Note 131 for St. 175 says: "Thorax 

 and abdomen heavily blotched and mottled with deep carmine on a pure white ground, 

 the amount of carmine pigment varying greatly in different specimens. Last three 

 thoracic legs dotted with carmine. Eyes shining salmon pink". 



This species is very likely a synonym of E. georgiana, Schell. 1931, p. 160.

Occurrence: 1. St. 45. South Georgia. 1 $ 13 mm. 



2. St. 123. South Georgia. 3 $? 11-13 mm. 



3. St. 140. South Georgia. 8 $$ 10-13 mm - 



4. St. 148. South Georgia. 1 <$ 10-5 mm. 



5. St. WS33. South Georgia. 1 $ 7 mm. 



6. St. MS 71. South Georgia. 1 juv. 5-5 mm. 



Remarks. The 7th peraeon segment ends in a short medio-dorsal point, the keels on 

 pleon segments 1 and 2 end in slightly more prominent points, and the triangular pro- 

 jection on segment 4 is more sharply pointed than in the Terra Nova specimens. The 

 hind margin of 2nd joint of peraeopod 5 is usually slightly indented distally, but the 

 lobe has a small point at the postero-inferior corner. 



The figure here given of the 2nd joint of peraeopod 3 shows the point of divergence 

 of the outer and inner keels right at the base, the strong sinuous expansion of the outer 

 keel, ending in a sharp point, into which the lateral longitudinal keel does not enter, and 

 the feeble expansion of the inner keel, which ends below in a small subacute lobe. In a 

 true external side-view the inner keel is scarcely visible below the concavity of the outer
