tinction is furnished by the spiracular plates beneath the 
fore extremity of the abdomen: these are of a bright white 
colour, and in some examples are shining and very con- 
spicuous. 
Three examples, all females, were found under stones on 
the Chesil beach, close to the Isle of Portland, in June 1875. 
This spider is also nearly allied to Z. puta, Cambr.; but it is 
rather larger, darker-coloured, and of a shorter, stouter form ; 
it is also easily distinguished from that species by the white 
spiracular plates.

Adult and immature examples of both sexes of this rare and 
local species were found in parts of Bloxworth Heath from 
the 7th to the 16th of June, 1877. This spider secretes itself 
under stones, but chiefly under the dry crust formed by the 
desiccation of the small muddy puddles which abound wher- 
ever the turf has been previously pared off for fuel. In these 
situations there is generally, until after midsummer, the 
amount of dampness so essential to the life of many spiders.

An adult male and two adult females were found in similar 
situations to those in which the last species was found, on the 
7th of June, 1877. 
The male differs very little in size, colour, or markings 
from the female (though both sexes vary considerably in re- 
spect to size) ; as, however, the male has not yet been described, 
it will be well to make one or two observations upon it. With 
regard to size, the length of the male found is 22 lines, that of 
one of the females very nearly 3 lines, the other female being 
just 2 lines. 
The palpi of the male are moderately long and tolerably 
strong, of a dull yellow colour, the radial and digital joints 
being tinged with dull orange-brown; the radial and cubital 
joints are short; the former is rather the shortest, and has its 
fore extremity on the outer side produced into a strong tapering
