a superficial conclusion from this material it seems that the spider 

 fauna of the Bermudas is more American than anything else, for 

 out of the seventeen species now known, only four are original (so 

 far) to these Islands and nine are found also in the limits of the 

 United States. 



Lycosa atlantica, nov. spec. 



Cephalothorax dark olivaceous brown, with a narrow, longitudinal 

 yellow band over the middle, which begins at the posterior margin 

 and runs over the whole length into the region of the first eye row. 

 Another, equally colored, but somewhat broader band runs at the 

 sides, above the lateral margin, terminating at the sides of the pars 

 cephalica. Mandibles dark brown with long, thick and black 

 pubescence. Maxillre and labium more reddish brown ; sternum 

 lighter, olivaceous yellow with a lighter border, hairy. Palpi and 

 legs uniformly light olivaceous yellow, with black hairs and 

 without rings or markings, tarsal joints of the former infuscated. 

 Abdomen : dorsum dark olivaceous brown with a narrow, whitish 

 slightly spear-shaped figure, which is edged by a very narrow 

 blackish line; behind this a row of four rather indistinct white 

 small round spots which reach the apex. Venter light yellow, 

 middle region still lighter. 



Cephalothorax as long as patella X, tibia IV; one-third longer than 

 wide ; back straight evenly sloping in back and front, face nearly 

 perpendicular. Lower eye row longer than second. Middle eyes 

 of lower row about twice as large as the lateral eyes. Distance 

 between the large eyes of the second row smaller than their 

 diameter ; eyes of the third row as large as middle ones of the first 

 row. Mandibles as long as tibia III. Cephalothorax long, 6 mm. ;. 

 broad, 4*5 in the middle region ; in front, 2*2.
