species, the last three pairs of limlis are a Uttle more slender than 

 the three preceding- pairs. 



The pleopods are nearl) as in the preceding" species^ but no 

 male appendage was discernible on the second pair- 



The uropods are as in the preceding species, except that the 

 outer ramus is as long as the inner, with a strong outward- 

 directed apical tooth, and that tiie whole appendage is strongly 

 fringed with setules- 



The specimen figured was ornamented by a narrow transverise 

 purple band near the hind margin of each per?eon segment, and 

 by transverse and longitudinal bands on the telsonic segment, 

 but this striking pattern was not repeated on other specimens. 



Length of unrolled specimen would be lo mm- 



Locality : — Between Bird Island and mainland, Algoa Bay, 

 dredged from depth of 10-16 fathoms. 



The specific name refers to the pubescence on man}'^ parts of 

 the integument- Between this species and E, vaUduni the alliance 

 is very close, but it has not seemed feasible to attribute all thd 

 differences mentioned to conditions of age or sex.

The synonymy of the species is given and discussed in the Pro- 

 ceedings of the Zoological Society for 1900, in combination with 

 that of White's Spliacroma lanccolatuni- On the whole, it now 

 seems to me that the two forms ought to be kept specifically 

 separate, and that the names allotted by Leach and White may 

 conveniently stand, although it may not be absolutely certain 

 •which of the forms Leach had before him- 



The South African specimens appear to be in substantial 

 agreement with those described and figured as Exospliacroma 

 gigas from Mr. Rupert A'allentin's Falkland Island collection, 

 ■except that in point of size they by no means merit their specific 

 name of gigas. They are quite small. The s])ccimcn dissected 

 was 9 mm. long by 5 mm- broad, with the male appendages well 

 ■developed, those on the second pleopods being considerably 

 longer than the rami. The first antennse have the 

 flagellum 11 -jointed, a little longer than the peduncle, 

 and in the second antennae the flagellum is 

 ig-jointed and considerably longer than the peduncle. 

 These numbers and dimensions contrast with those in the large 

 Falkland Islands specimen, in which the first tlagellum is 17- 

 jointed but shorter than the peduncle, and the second has about 

 16 joints- These flagcUa. however, are notoriously subject to
