[Read before the Otago Institute, 9th October, 1877.] 
Ix the year 1874 I received from Capt. Hutton an adult female example of* 
Nemesia (found at Oamaru), but upon which, owing to its damaged condition, 
no reliable opinion could be formed. In the following year Capt. Hutton 
again forwarded me several females of the same species, from the same 
locality, with some particulars respecting their habits and nests observed 
by Mr. R. Gillies, and the welcome information that that gentleman 
purposed to record his numerous observations in a paper to be read before 
the Otago Institute. These specimens were also much damaged before they 
reached me, but, so far as they afforded means of determination, I was at 
first inclined to think that they comprised two very nearly allied, but 
probably distinct, species. In another bottle of various spiders, received at 
the same time and from the same locality, there was an adult male example 
(in excellent condition) of a Nemesia, which I have but little doubt is the 
male sex of the species to which the females that accompanied it belong. 
More recently still, Capt. Hutton has kindly sent me eight or nine adult 
females and numerous immature ones (mostly in good condition), upon the 
several nests of which Mr. Gillies’ long and interesting paper has been 
published.t I have come to the conclusion, after long and repeated exam- 
inations and comparisons with each other, that, in spite of a considerable 
difference in size, all these examples (received at the various times mentioned 
above) belong to one and the same species, upon which I beg to confer the 
name of its discoverer, and to call it Nemesia gilliesii. - 
From Mr. Gillies’ paper (l.c., p. 225) I understand that the nest— 
No. 1, pl. viii. (l.c.)J—is supposed to have belonged to one of the female 
examples first sent to me by Capt. Hutton. This nest is of a decidedly 
different type from all the rest, having a branch issuing from near the 
middle, and furnished not only with a door to the main tube, but with an 
inner door or valve at the entrance to the branch. All the other nests are, 
although slightly varied in some characters, of one type, consisting of a 
* The spiders referred to in this paper are very nearly allied to, and perhaps identieal 
3, changed to Arbanitis,l. c., p. 491). The distinction, however, from Nemesia consists 
chiefly, if not wholly, in the denticulation of the tarsal claws, and seems scarcely 
ae enough to require the formation of a distinct genus; especially as in the 
present species (which is quite a different one from that described by Dr. Koch) the 
denticulation of the tarsal claws of the female differs from that of the male.
