spotted with black (in nigropalpis iisiialh' blackish) ; finally the cepha- 

 lothoracal median yellow band usually encloses a broad rcddish-browai 

 area at its anterior end (usually not so in nigropolpis) . Of all these 

 differences the only one that appears to be constant is the first. Min- 

 ima averages smaller in size, but then nigropalpis is very variable in 

 this respect; and nigropalpis has generally the dark annulations on 

 the legs much more distinct, but some individuals of minima from 

 Wood's Hole, Massachusetts, have the legs just as distinctly banded. 



Pardosa glacialis (Thor.). PL XIX. fig. 25 



Lycosa glacialis Tliorell, 1S72. 

 Pardosa brunnea Emerton, 1885. 



(Specimens from Mt, Washington, New Hampshire.) 

 Eyes. — First row narrower than the second, nearer to the second 

 row than the clypeal margin, middle eyes larger and distinctly lower. 

 Eyes of second row largest, separated by fully 1.5 times their diameter. 

 Dorsal eye area to cephalothorax as 1 : 4.5. Quadrilateral of the 

 posterior eyes broader than long. 



Form. — Cephalothorax highest at the posterior eyes, in front less 

 than one-half its greatest transverse diameter, sides of head rather 

 vertical. Chelicera wdth three pairs of teeth, longer than the breadth 

 of the clypeus, in length 1.5 times the height of the head in front. 

 Labium longer than broad, rounded at the tip, not one-half the length 

 of the maxillae. Sternum longer than broad, pointed behind. Pos- 

 terior spinnerets about 1.5 times as long as the anterior. Metatarsus 

 IV slightly longer than patella and tibia combined, leg IV to cephalo- 

 thorax as 4.3 : 1, the legs rather hairy with weak scopula?. 9 palpal 

 claw with 4 teeth. Tibia I with 3 ventral pairs of spines. 



Pardosa groenlandica (Thor.). 



Lycosa groenlandica Thorell, 1872. 

 Pardosa albomaculata Emerton, 1885. 



(Specimens from Mt. Washington, New Hampshire.) 

 Eyes. — First row shorter than the second, much nearer to it than to 

 the clypeal margin, about straight, eyes adequal. Eyes of the second 

 row largest, about 1.5 times their diameter apart. Dorsal eye area to 

 length of cephalothorax as 1 : 4.5. Quadrilateral of the middle eyes 

 broader than long. 



Form. — Cephalothorax highest at the posterior eyes, in front one- 

 half its greatest transverse diameter, sides of the head steep. Chelicera 

 with 3 pairs of teeth, in length more than the width of the clypeus and 

 1.5 times the height of the head in front. Labium longer than broad, 

 truncated apically, not one-half the length of the maxillse. Sternum
