Spiders and Optliones.] SUBANTARCTIC ISLANDS OF NEW ZEALAND. 167 



Tliree females were collected by Mr. G. R. Marriner, after whom I have named 

 it, from under stones on the sea-shore, at Monument Harbour, Campbell Island. 



This species, while nearly allied to the genera Ci/hoeufi. Cyboeolus, and Cedicus, 

 of E. Simon, differs from Ci/hoeus in having 5 ec|ually large teeth and 1 small on 

 the outer margin of the falx-sheath. instead of 1 large between 2 smaller ; and in 

 having the legs scarcely bespined at all, instead of strongly bespined ; also in its 

 distinctly 2-jointed instead of 1 -jointed spinnerets. 



It resembles (Jedicus in the largely dentated inner margin to its falx-sheath ; 

 in its colulus ; its front median eyes, much nearer one another than to the laterals ; 

 and in its spinnerets : but differs in its shorter lip. wider clypeus. and straight or 

 recurved front row of eyes instead of procurved. 



It resembles Cyhoeolus in the smooth metatarsi of its front 2 pairs of legs ; in 

 its rear median eyes, nearer to one another than to the laterals : but differs in its 

 unequally-sized front row of eyes, its convex mandibles, and broad-to])])ed li|), as 

 well as where CijhoeoJus agrees with Cyhoeus as above noted. 



A single smaller but adult female from Enderby Island (Auckland Islands) 

 is clearly the same as the above-described from Campbell Islands, the only difference 

 being that the legs are shorter in proportion to the cephalothorax and abdomen, 

 and colouring rather darker. 



The measurements (in millimetres) are as follows : Cephalothorax, 2| mm. 

 long, 2 mm. broad (1^ mm. in front) ; abdomen. 4 mm. long. 3 mm. broad ; 

 mandibles, 1^ mm. long. 



Legs. Coxae.

Rubrius nummosus, nov. sp. (Plate VIII, figs. 2a-'2d.) 



Cephalothorax bright red-brown, darker at the sides of the cephalic part and the 

 eye-space. Mandibles dark red-brown, with yellow muscle-spots at base. Fangs 

 black-brown at base, red-brown at lower half. Lip, maxillae, sternum, legs, and 

 palpi slightly darker than the cephalothorax. 



The (thdomen is rather bright yellow-brown in front and at the sides : at one- 

 third of the distance from the base is a dark-grey median line, with 4 |)airs of wavy
