from Spitsbergen and Bear Islatid. 1C)7 



at least four species of Micnria liave l)een described from the 

 Arctic regions ; tlic^^e are : — .1/. /I'loiilis, Kiilcz. (4), M. cen- 

 trocnenils, Kulcz. (4), M. cenea, Tlior. (' Remarks on Syno- 

 nyms of European Spiders,' 1870-1873, p. 175), and M.fo- 

 veata, Strand (5) — the two former from Siberia and the two 

 latter from northern Norway. Of M. labradoriensis, Marx, 

 from Labrador, T iiave no information beyond its existence. 



M. eltonli may turn out to be the male of arjy of these, the 

 first four of which are only known in the female sex ; but 

 from tiie descriptions of these I should think it quite 

 unlikely. The proper course seems to be to describe it now. 



This is the first spider not an Argiopid to be found in 

 Spitsberi^en. It belongs, of course, to the family Clubionidre. 



Fades. — Resembles a large specimen of ^^. pulicaria, but 

 has no white abdominal bands or spots. The specimen 

 shows a few thick white hairs on each side of the cephalo- 

 thorax near its base, but these are not numerous enough to 

 be seen without a microscope. 



Length. — Cephalothorax Id mm., abdomen 2*1 mm., total 

 3' 6 mm. 



CepIialotJiora.v. — Smooth, dark reddish brown, mottled and 

 striped with deeper brown markings radiating from a dark 

 wedge-shaped mark at the thoracic juncture. Covered with 

 very fine white pubescence, and showing the aforesaid patches 

 of thickened white hairs towards its posterior border. 



Stej'}nim. — Dark red brown, almost black, covered with 

 long fine hairs and without sqnanies. 



Eges. — Anterior row strongly procurved — i. e., concave in 

 front, ('entrals the smallest, each more than a diameter 

 apart and less than a diameter from the adjacent laterals. 



Posterior row slightly procurved. Eyes subequal or centrals 

 slightly less than laterals, all elliptical in shape. Centrals 

 obliquely placed, more than a diameter apart and about the 

 same distance from the laterals. 



Falces. — Dark red-brown ; not rugose, bearing no squames, 

 covered with long bristly hairs. 



Palpi. — Maxilire dark red-brown, with a whitish patcli at 

 the tip on the inner side. 



Femur, patella, and tibia yellow-brown, marbled with 

 darker brown, and darker above than below. 



Tarsus dark brown, almost black, paler at the tip. It bears 

 on its under surface between the palpal organs and the tip 

 three long strong spines, the one present in some other 

 species on the outer side being absent ; all these articles are 

 covered witli long simple hairs. 



The patella is '25 mm. long and 'lo mm. broad from side
