Gitres.—On the Habits of the Trap-door Spider, 225 
the same locality as the one I first discovered, and may have had a double 
branched nest, as the soil was so loose and friable, that in digging it out, 
it was impossible to tell through the nest getting spoiled. Another from the 
same locality was one of those which were sent home to Rev. P. Cambridge, 
and it had a side gallery and double trap-door, as shown in sketch No. 1, 
Plate VIII., which I will describe further on. This is the only instance of 
this peculiarity which has been observed, and asit was not seen by myself, but 
by one of my servants, I do not attach great weight toit. It may, how- 
ever, account for the two different species referred to by Rev. P. Cambridge. 
Another specimen, and the pieces of the nest, had a peculiar greyish colour 
different from others. It was found in a different locality, in a very peculiar 
situation, the foot of the corner post of a stable, and had its trap-door de- 
pressed under the general surface of the ground as afterwards described. 
The cephalo-thorax in another, is peculiarly large and broad, and its nest is 
figured in Plate VII. It was got from a different locality, called the Bobbin 
Creek, and all the nests in that locality have this peculiarity—they are lined 
with silk about two-thirds down only, the bottom part being unlined. Speci- 
mens of part of this nest are also before you. The spider and young ones 
in the bottle were from a different locality, the Stable Gully, and several of 
the young ones had a greenish-blue spot on them, and some of them brown, 
before they were put into the spirits. Another from the same locality, had 
a slightly different nest, as seen in Plate VIL., and all those from this locality 
had by far the most ingeniously concealed trap-doors, though the nests were 
smaller than those elsewhere. Another from the same locality was much 
darker in colour, and larger, and had a very peculiar nest, figured in Sketch 
No. 6, Plate VIII., and afterwards described. Another lot of about half- 
a-dozen, with several young ones, from the same locality, are all of smallish 
size. They were of a dark olive tint, and turned lighter in colour in 
the spirits. Some of these were actually got crawling about outside of 
their holes, and some were dug out. One little one of these was of such 
a peculiar colour, that I kept it distinct. It was mostly of a pale binish- 
green or greenish-blue colour, and some parts colourless. it was quite 
different in colour to every other one I ever got, 80 I hope it may be a 
male, as males are very rare, and difficult to get. These are really the only 
differences readily noticeable in the spiders themselves, ae 
of size. There are greater differences, however, in their nests and trap- 
doors, &¢., which will be noticed further on, and which may help in the 
determination of their species. ne ’
