along its outer margin with very strong barbed spines ; lobe from second segment long and narrow, 

 armed distally with a group of long plumose setae. This lobe is continued backwards as a flat ridge 

 fused with the segment and armed along its outer edge with 9-10 very long plumose setae; no lobes 

 from third and fourth segments ; one very strong plumose seta similar to those on the exopod of the 

 maxilla at the outer distal angle of the second, third and fourth segments (Fig. 28 F). Third to the eighth 

 thoracic appendages. All the endopods of these appendages are missing. Pleopods of the female 

 reduced to very small plates. Uropods unusually long with the exopod almost three times as long as the 



Fig. 28. Heteroerythrops purpura gen.n., sp.n. A, anterior end of adult female in dorsal view, x 18 ; B, antennular peduncle of 

 adult female, x 36; C, right antenna, x 36; D, mandibular palp, x 36; E, maxilla, x 36; F, endopod of first thoracic appendage, 

 x 36; G, endopod of second thoracic appendage, x 36; H, telson and right uropod, x 36. 



telson ; apex truncate and rather broad ; endopod almost as long as the exopod. I can find no spines 

 among the setae on the inner margin (Fig. 28 H). Telson small, triangular, with the lateral margins 

 sub-equal in length to the width at the base; slightly more than half as long as the last abdominal 

 somite ; no spines on the lateral margins ; apex narrowly truncate. Only the proximal portion of one 

 spine is present and the posterior margin of the apex is damaged, so that I am unable to ascertain how 

 many spines were originally borne there. I am inclined to think that there were only two spines ; if 

 there had been more, the inner ones must have been much more slender than the only base which is 

 still attached. It may be that there were two plumose setae (Fig. 28 H) 

 Length of female with large, well-developed marsupium, 6-2 mm.
