tella and tibia of the fourth pair, 4.5 millim. ; tibia somewhat more than 

 3.33 millim. 



?. Length, 8 millim. ; cephalothorax, 4 millim. in length, nearly 3 

 millim. in breadth; legs of the first pair, 11.5 millim., of the second 

 and third pairs, 11.25 millim. ; fourth pair, 16.5 millim. ; patella and 

 tibia of fourth pair, 5 millim.; tibia somewhat more than 3 millim. 



The above described male and female were found in Square Island 

 (July), another male near Dumplin Harbor (or Sloop Harbor). 

 The species may, I think, be without difficulty distinguished from 

 the next following, and other nearly related species, by the form of 

 the middle band of the cephalothorax, and the structure of the sex- 

 ual organs.

Female. — Cephalothorax slightly shorter than tibia and patella of 

 the fourth pair, with the back straight, not depressed behind the eyes, 

 and the sides of the pars cephalica, seen from in front, evidently 

 sloping; brownish black, with three longitudinal pale bands, the mid- 

 dle one short, reaching the pars cephalica only, and geminated by 

 the fine, black, central furrow, about as broad as the anterior tibiae, 

 tapering behind ; the lateral bands of about the same breadth, supra- 

 marginal, continuous (or perhaps slightly interrupted once or twice?) 

 coarsely dentated in the upper margin. Sternum black. The front 

 row of eyes nearly straight, scarcely perceptibly curved forwards ; its 

 eyes of equal size, the centrals somewhat more distant from each 

 other than from the laterals. The eyes of the second series are sep- 

 arated by an interval much greater than (nearly double as great as) 

 their diameter. Mandibles dark brown, their back rather strongly 

 convex longitudinally ; rather longer than patellae of the first pair. 

 Maxillae brownish. Palpi of a dull brown color, the femoral joint 

 with black spots. Legs of a dull brownish color, the thighs some-
