Systematic Notes on Various Species. 



In the notes given in the following pages two new species are 

 described, and there is also a complete description of Chelifer can- 

 croides. Most of the species mentioned have never been figured 

 before. 

 Chelifer cancroides Linn. (PI. I and II, all Figs.). 



Male. — General appearance a chestnut brown, but the hands, fingers and 

 the cephalothorax darker than the rest of the body ; legs slightly paler than 

 the abdomen. Integument of the cephalothorax and first four segments of 

 the palpi evenly tuberculate. 



Chelicerae about as long as the distance between the eyes on the cephalo- 

 thorax ; movable digit with the outer margin almost straight ; spinneret hya- 

 line, about three times as long as broad and ending in four small cusps. 

 Pedipalps rather long and slender ; trochanter subglobose, but more projecting 

 on the posterior side where it has a tendency to become angulate ; from this 

 point extends a rather prominent hair ; femur slightly longer than the cephalo- 

 thorax, constricted at its base and increasing slightly in width as you pass to 

 the distal end ; tibia almost as long and slightly wider than the femur, notched 

 on its anterior margin at the base ; hand as long as the tibia and about one 

 and a half times as broad ; fingers very slender, distinctly longer than the hand 

 and evenly curved. The trochanter of the pedipalps is rather well clothed on 

 its anterior surface, with short, stout almost clavate hairs ; femur and tibia 

 with fewer and more slender but similar hairs ; hairs on the hand and fingers 

 simple, and tapering, those on the fingers of two sizes, short numerous ones 

 and about 5 very long tactile hairs on each digit. 



Cephalothorax about one and a third times as long as broad ; a single pair 

 of eyes present, cornea distinct ; two or three small chitinous tubercles present 

 on each side of cephalothorax. 



Abdomen considerably broader than the cephalothorax, broadest near its
