resembles it very closely in general appearance, colours, and 

 markings, though its general hue is often of a redder-brown tinge. 

 If the following differences are noted, the two species need never 

 be confounded with each other. 



The central pair of eyes of the anterior row are only a little 

 larger than the laterals, the row itself being nearer to the falces ; 

 the metatarsi and tibia}, only, of the first pair of legs are of a 

 dark brown hue, and all the femora are faintly annulated 

 with olive-brown. The sub-marginal yellow-brown band on the 

 cephalo-thorax is generally more or less interrupted or broken. 

 The normal marking on the fore half of the upper side of the 

 abdomen is of the same hue as the surrounding surface, and 

 only indicated by its dark marginal line ; it emits an oblique 

 dark line on each side towards its hinder extremity, which is 

 narrowor then the rost, but truncated, with its corners a little 

 produced on each side in an oblique direotion. 



The palpi (of the male) are rather shorter than those of 

 Trochosa ruricola, but the digital joint is larger and broader, and 

 has no terminal curved spine. 



The female of the present species may be distinguished from 

 that of Trochosa ruricola, not only (like the male) by the smaller 

 central eyes of the anterior row, and the form and colour of the 

 normal marking on the abdomen, but also by the size and form 

 of the genital aperture ; this is large and conspicuous in the 

 present, but very much smaller and inconspicuous in the former 

 species. 



Trochosa terricola is a more abundant spider at Bloxworth than 

 Trochosa ruricola. It inhabits, generally, similar situations, but 

 is of tener found among moss and dead leaves in woods, and among 

 moss and heather on heaths and wastes. The egg-cocoon and 

 its contents are very nearly similar to those of Trochosa ruricola, 

 and the spidor itself often hybernates in a similarly excavated 

 hole in the earth under a stone. 



I have received this spider from various other parts of Dorset- 

 shire ; and it is of frequent occurrence in numerous localities in 

 England, Scotland, and Wales.
