be P. oblongus, Walck.-BL, and T. maritimus, Menge, 

 male non female (the female of maritimus, Menge, being 

 the female of Kulczynski's and Menge's oblongus). The 

 Tibellus oblongus described by M. Simon as the Thomisus 

 andPhilodromus oblongus, Walckenaer (Arachn.de France 

 II., p. 311) appears to be quite of another species. 

 Tibellus propinquus, Simon I.e., p. 309, would seem to 

 be more probably identical with T. oblongus, Walck.-Bl., 

 but in the absence of comparison with types of the latter 

 it is uncertain.

It is at present unlikely that any reliable records exist 

 -as to the respective habitats and abundance of this and 

 the next species, inasmuch as hitherto the two forms have 

 been mixed up, and collectors have not had their attention 

 directed to these points ; but as far as my experience 

 goes I should say that the present species (oblongus, 

 Walck.-Bl.), frequents, generally, marshy spots, while the 

 next (T., maritimus, Menge), seems to be more addicted to 

 dry and sandy localities, and is, perhaps, the most 

 abundant of the two. More accurate records will, 

 however, now be kept by collectors on these two points. 

 Both species will probably be found to be tolerably 

 abundant and widely distributed, and perhaps often 

 inhabiting the same localities.
