On the Genus Tragosia, Gray. 169 
Two species have been recorded from Spitsbergen which 
Mr. Elton did not meet; these are :— 
Leptyphantes hyperboreus, Strand (10).—An adult male and 
an immature female. 
Micryphantes fuscipalpis, C. L. K.—One female. 
This is an extremely critical genus, and the identification 
is very doubtful. It is far more likely to be JL. nigripes, 
Sim., or some other form. It is absolutely necessary to have 
males in order to be sure of the species.

Tur genus Jragosia was proposed by Gray [1867] with 
T. infundibuliformis as its type-species. This species is the 
Isodictya infundibuliformis of Bowerbank [1866, 1874 | 
and the Halichondria infundibuliformis of Fleming [1828 | 
and Johnston [1842]. Perhaps this is as far-as it is safe 
to go in tracing back the synonymy, but Johnston expresses
