ventral bristles. Dorsally is the somewhat short subulate 

 dorsal cirrus, the tip of which falls short of the setigerous 

 region, which forms a thick truncated lobe, separated by a brief 

 interval from the short and blunt ventral cirrus. The wliole 

 foot is richly vascular. The setigerous region bears above the 

 spine a tuft of bristles with tapering tips, which have but faint 

 indication of wings. A few brush-shaped forms are also present. 

 Beneath the spine is a dense group of compound bristles with 

 straight shafts, which are bent backwards and dilated at the tip, 

 as well as bevelled for the terminal piece — which is somewhat 

 short, biiid at the tip, and with wings. 



The intestine contained sandv mud with fragments of sponge- 

 spicules, echinoderms, and small calcareous fragments. 



The specimen named bv Grube Lysidicc capc'iisis* seems to 

 have been verv small, onlv 21 mm. in length, but its general 

 characters a< well as the structure of the foot correspond. 



Except in the coloration, Schmarda'^ Lysidicc atra from the 

 Cape agrees with this form. When the feet of the latter are 

 contrasted with those '^f Lxsidicc Xiuctia the African has black 

 spines whilst the other has yellow spines, and the tips of the 

 compound bristles appear to be slightly shorter in the African. 



Some of the examples had free ova of a greyish colour in the 

 perivisceral chamber, so that the breeding season would be at 

 the time of capture. 



As Langerhans found Lysidicc Xiuctia as far south as Madeira 

 and the Canaries, it may yet be possible to reduce the number 

 of species of this genus, and it may be that the form from the 

 Cape will be placed as a variety of the European. The litera- 

 ture of this genus is much in need of critical revision. 



It is curious that no example of the genus was procured 

 during the voyage of H.M. Ship "Challenger."
