PARAMPHITHOIDAE

(1930, fig. 43 c); the dactyl bears a series of slender spines separated by short spaces. 

 The postero-inferior angles of the 2nd joints of peraeopods 3 and 4 are more rounded- 

 quadrate, especially in peraeopod 3. There is one inter-antennal tubercle. 



Specimen no. 2 has pleon segment 3 terminating in a more prominent blunt process, 

 the posterior prominence on segment 4 is higher and symmetrically rounded, and the

Fig. no. Epimeriellawalkeri, Brnrd. a. Gnathopod 1. b. Pleon segments 1-6. c,d,e. 2nd 

 (and 3rd) joints of peraeopods 3-5. (b-e are from the specimen from St. 182.) 



postero-inferior angles of the 2nd joints of peraeopods 3 and 4 are quite rounded; but 

 in other respects it resembles the other specimens. This specimen is recorded as being 

 "pure white with pink eyes". 



Distribution. McMurdo Sound, 256-379 m.

All the present specimens have a normal 4-jointed palp in the maxilliped, and the 

 original generic definition must therefore be altered. The 4th joint is often difficult to 

 see on account of the thick brush of setae on the 3rd joint.
