 Both sexes. 



A. Slaithwaite : Armitag'e Bridj^e. 



C. Scarboroui^h Mere : North Bay : Raincliff : Ringingf- 

 keld Boy^, Cloug'hton : Hayburn Wyke. 

 One of the most abundant species and the one which most 

 readily dispenses with its legs ; seen in autumn running over 

 the grass and herbage, or stationary under coping stones and 

 in crannies of walls ; often in masses on the under surfaces of 

 projecting rocks, beams, &c.

 Both sexes. 



C. Scarborough Mere : North Bay : Cloughton : Hayburn 

 Wyke. 

 Another very abundant species amongst grass and vegeta- 

 tion. One of the joints of the falx of the male develops a 

 strong, pointed, slightly curved horn, which is very variable 

 in size and strength, the variability being dependant on the age 

 of the individual as well as on the season.* 



Phalangium par ietiiiuni De Geer. 

 Both sexes. 



A. Slaithwaite, six examples. 



B. Gipton Wood, one example. 



This harvestman affects a different habitat from the last. 

 All the examples here recorded were taken either when wandering- 

 across a paved yard or in rooms of houses. 



Phalangitim saxatile C. L. Koch. 



C. Scarborough, North Bay. 



On the coast, at roots of grass. Both sexes in plenty.
