ORDER PULMONART^. - 421 



Senelops, Dufour, 



Form the passage from the preceding subgenus to the follow- 

 ing: the jaws are straight, or but very little inclined, without 

 lateral sinus, and proceed into a point, being truncated 

 obliquely at the internal side. The tongue is semi-circular, 

 like that of the micrommata ; but the eyes are differently dis- 

 posed : there are six in front, forming a transverse line ; the 

 other two are posterior, and situated, one on each side, behind 

 each extremity of the preceding line. The feet are long ; the 

 second, and then those of the two following pair, exceed the 

 first two in length. 



The species w'hich serve as type, Senelops omalosoma, 

 (Dufour, Ann. des Scienc. phys. V. Ixix. 4.) has been found 

 by M. Dufour in the kingdom of Valencia, but it is very rare 

 there. Its body is about four lines in length, very flatted, of 

 a reddish grey, with ash -coloured spots, and black rings to 

 the feet ; the abdomen appears to present behind some 

 vestiges of rings, forming laterally the appearances of teeth. 

 It inhabits rocks, and flies with the rapidity of an arrow. It 

 is also found in Syria, (Collection of M. de Labillardiere) and 

 Egypt, Senegal, the Cape of Good Hope, and the Isle of 

 France, furnish other species of the same subgenus. 



Philodromus, Walck., 



Differ from the two preceding subgenera, by having their 

 jaws inclined upon the tongue. This part also is more high 

 than broad. The eyes almost equal among themselves, always 

 form a crescent, or a semi-circle ; the lateral ones are never 

 placed on tubercles, or eminences; the forceps are elongated 

 and cylindrical ; the last four, or the last two feet, do not 

 differ remarkably in length from the preceding. 



According to M. Walckenaer, these araneides run with 

 rapidity, the feet extended laterally, watch for their prey,
