306 PROCEEDINGS OF THE ACADEMY OF [March, 



Eyes. — First row straight, as broad as the second, nearer the clypeal 

 margin than to the second row, middle eyes fully twice as large as the 

 lateral. Eyes of second row largest, their diameter apart. Dorsal 

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

 eyes slightly longer than broad. 



Fonn.— Cephalothorax highest between the posterior eyes and the 

 dorsal groove, in front more than one-half its greatest transverse diam- 

 eter ( 9 ) or less (d^) and truncated (9) or rounded (d^). Sides of 

 head moderately oblique and rounded. Chelicera with 3 pairs of teeth, 

 much longer than the width of the clypeus, in length about 2.5 times 

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

 apically, fully one-half the length of the maxilljp. Legs strong with 

 short spines ; leg IV to cephalothorax as 4 : 1 ; metatarsus IV shorter 

 than patella and tibia combined. 9 palpal claw with 3 minute teeth. 

 (^ palpal tibia twice as long as the patella, and narrower, the point of 

 the tarsus fully as long as the bulbus. Anterior spinnerets longest. 



Comparisons. — This differs from the European form, judging from 

 Simon's description {Arachnides de France), in that the fourth tibia and 

 patella combined are considerably longer than the cephalothorax 

 (instead of the same length), and in that the fourth leg is 4 times the 

 length of the cephalothorax instead of 3.3 times. The two species may 

 prove to be distinct. 



The Texas specimens differ from the northern ones in large size 

 ( 9 with a cephalothoracal length of 7.5 mm.), and in being much paler 

 colored. 



Habits. — In the North this is a species of the sea coast. At Austin 

 it is common, particularly in the fall, under stones close to fresh water. 



Trocliosa frondicola (Emerton).

(Specimens from Pennsylvania and Massachusetts.) 

 Eyes. — First row fully as broad as the second, middle eyes larger 

 and slightly lower, nearer the clypeal margin than to the second row. 

 Eyes of second row largest, 1.4 times their diameter apart. Dorsal 

 eye area to cephalothorax as 1:5. Quadrilateral of the posterior 

 eyes broader than long. 



Form. — Cephalothorax slightly highest behind the middle, in front 

 truncated and quite (c?) or more than ( 9 ) one-half its greatest trans- 

 verse diameter, with the sides of the head oblique. Chelicera with 3 

 pairs of teeth, longer than the width of the clypeus, their length twice
