of the clypeus is no more than equal to the diameter of one of the 

 fore-central eyes. 



Eyes of a dark yellowish-grey colour ; those of the posterior row 

 are about equally separated from each other, the hind-centrals being 

 rather smaller than the hiud-laterals ; the fore-centrals are minute, 

 much the smallest of the eight, difficult to be seen, and equally re- 

 moved from eacli other and the fore-laterals ; the four central eyes 

 form a rectangular figure whose posterior side is the longest and its 

 anterior the shortest. 



Legs yellow-brown ; the tibiae, tarsi, and metatarsi of the first and 

 second pairs dark reddish brown. 



Palpi similar in colour to the first two pairs of legs, and ending 

 with a small curved claw. 



Falces nearly black, with some strong teeth on the inner margin 

 near the fore extremity ; their anterior surface is roughened or 

 finely rugulose, and the fang strong. 



MaxillcB and labium deep blackish red-brown. 



Sternum yellowish brown, with prominences round the margins, 

 opposite the insertions of the legs. 



The abdomen projects fairly over the base of the cephalothorax ; 

 its upperside is yellow, with a strong central longitudinal bar on the 

 fore half, strongly bifid in a fish-tail form at its hinder extremity, 

 and with two or three prominent spots or blunt points on the sides ; 

 following this to the spinners are five transverse angular bars or 

 chevrons divided or interrujited at the angles ; all these markings 

 are of a deep blackish chocolate-brown, the sides being of the same 

 colour, softening off gradually into yellowish on the underside ; a 

 large obtuse patch of the dark colour obtrudes from the sides at the 

 fore part into the upper yellow area, touching (on each side) the 

 middle prominent point on the side of the central longitudinal bar ; 

 the sides are also traversed by a curved, more or less continuous, yellow 

 tapering stripe, which breaks out from the middle of the upper sur- 

 face and runs obliquely backwards ; there are also a few more yellow 

 spots behind these, sometimes forming curved lines, which also run 

 obliquely backwards. 



Genital aperture small and not very conspicuous. 



An adult and three immature examples of the female of this Spider, 

 found by the late Dr. Smith on rocks in the sea at Allday Bay, 

 Otago, were sent to me by Captain F. W. Huttou. They 

 came to me labelled " Marine Spiders ;" but whether inarine in the 

 sense of passing any portion of their existence under water, like 

 Mobsonia marina, I do not know. 



Independently of any peculiarity of habit, however, this Spider is 

 of great interest as being undoubtedly a Drassid, but bearing a near 

 resemblance to Amaurobius in general form, appearance, and pattern; 

 while in its eye-position, maxillce, and falces it is most like Clubiona, 

 the falces especially being very similar to those of Clubiona holo- 

 sericea, De Geer.
