274 SPECIFIC DESCRIPTIONS OF 



In the Menione Spider ^\qyq are three orange-yellow- 

 brown well-defined bars or longitudinal lines between 

 the ocular area and the thoracic fovea; the central 

 bar tapers and reaches from the eyes to the fovea, the 

 lateral ones never more than two-thirds of the distance 

 from it to the eyes, diverging a little from tlie central 

 bar as they run forwards. These two lateral bars are 

 not straight, i.e., their margins are more or less 

 notched or roughly angular, forming in some examples 

 a line of a somewhat zigzag or bent character. It may 

 perhaps be observed that when the two dark brown 

 lines which run along the broad orangeyellow-brown 

 band on the caput of the Montpellier spider, are well 

 marked, this also leaves three longitudinal yellow 

 lines, somewhat similar to those just described in the 

 Mentone species, but there is this difierence even then 

 (and it is constant throughout a long series of ex- 

 amples), the lateral lines in the Montpellier spider 

 always run througli to the eyes, equalling in length the 

 central line, while in the Mentone spider the lateral 

 bars never reach the eyes, always stopping short of the 

 ocular area, by one-half, or nearly so, of their length. 



Another distinction which appears constant is the 

 form of the thoracic fovea ; in the Montpellier species 

 this forms a slight but uniform curve ; in the Men- 

 tone spider it is more sharply bent at the apex (or 

 centre of the curve), forming in most examples a 

 bluntish-angular line. 



In the eyes there appears to be but little reliable 

 diiference ; if there be any at all constant, it seems to 

 be that in the present (Mentone) species the fore- 

 laterals are constantly smaller than the hind-laterals, 

 and sometimes smaller than the fore-centrals. A close
