mised to me by Mr. Workman; and I venture again to ask 
other Irish naturalists to collect and send me spiders from 
their several localities, so that after a while I may have a fair 
amount of material for a ‘ List of the Spiders of Ireland.” 
Collectors need not be at the trouble of separating their cap- 
tures; all I desire is some of every kind ;, and these can be 
safely sent to me by post in strong half-ounce or one-ounce 
phials.

Since the publication of my last notice of this species (J. ce. 
supra) no further materials have come before me for the more 
satisfactory determination of the synonymic position of this 
and our other species of the genus Atypus. I have, however, 
lately found a. strong colony of this spider under the over- 
hanging ledges of a heathy bank on Bloxworth Heath ; and 
examples of both sexes in the adult state have been kindly 
sent to me not long since from Hampstead by Mr. F. Enock of 
London. The remarks made (t. c. p. 240) upon the nests of 
A, Sulzeri, have been fully confirmed by the observations made 
since upon the nests dug out here, and upon those received 
from Mr. Enock. On one point, however, I am still in doubt; 
and that is, in regard to the branch occasionally found leading 
into, or out of, the main tube. Out of ten tubes dug out on 
Bloxworth Heath, four were furnished with a branch ; but no 
two of them exactly resemble each other, either in the size or 
in the position of the branch. In one instance the branch 
issued from the tube at about 23 inches from its lower extre- 
mity, and, running upwards at an acute angle, protruded from 
the surface among the heather-stems, exactly like the main 
tube and at about 3 inches from it, the branch, however, 
being about half the size of the tube, which measured 84 inches 
in length. In another instance the branch issued from the 
tube at about the same distance from its lower extremity, but, 
instead of running upwards, it ran downwards, at an acute 
angle, toa depth of about 2 inches, being, however, as large as,
