species, the last three pairs of liml)S are a httle more slender than 

 the three preceding pairs. 



The pleopods are nearly 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 the whole appendage is strongly- 

 fringed with setules- 



The specimen figured was ornamented by a narrow transverse 

 purple band near the hind margin of each person 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 many parts of 

 the integument- Between this species and E. ralidiim the alliance 

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

 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 AMiite's SpJiacroma lanccolatum- On the whole, it noAv 

 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 

 Avhich of the forms Leach had before him- 



The South African specimens appear to be in substantial 

 agreement with those described and figured as Exosphaerouia 

 gigas from Mr. Rupert \'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 specimen 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 antennae have the 

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

 and in the second antennae the ilagellum is 

 iQ-jointed and considerably longer than the ppduncle. 

 These numbers and dimensions contrast with those in the large 

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

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

 16 joints- These fiagcUa, however, are notoriously subject to
