always found in a tubular nest, but frequently in holes, crevices of banks, 

 walls, mounds of rubbish and stones, as well as under logs of wood, and 

 beneath loose bark, sometimes also in dark out-buildings, and often wander- 

 ing about at night. 



The folloY/ing is a detailed description of one of the spiders last received 

 from Captain Hutton, and belonging to one (though, from the cause men- 

 tioned in a note to p. 283, it is uncertain to which) of the nests figured by Mr. 

 Gillies. I have selected it out of the eight or nine examples received as a 

 type of the species, from its medium size, as well as because in its colours 

 and markings it is intermediate between the darkest and most confluently 

 marked, and the lightest and least confluent specimens. To this description 

 I have afso added one of the male sjpider, which (as before observed) I 

 consider to be that sex of the species to which the female spider described 

 belongs ; and I beg to return my best thanks both to Mr. Gillies and Capt. 

 Hutton for their kindness in sending me the materials for these observations 

 and descriptions. 



[P.S. — A point is mentioned in Mr. Gillies's paper (pp. 251-253) upon 

 which I have, as yet, made no remark, chiefly because it is at present to 

 me, as it is also to him, quite inexplicable — I allude to the nests which have 

 been found covered and hermetically sealed up on the outside with clay or 

 soil, and yet with the s^Dider alive inside. Subsequent observations made 

 by Mr. Gillies confirm the fact of this extraordinary seahng-up, which he 

 attributes to the male spider. But for Mr. Gillies having suspected and 

 searched in vain for a second tube with another external opening, I should 

 have suggested this as a solution of the mystery.]

 Nemesia gilliesii, sp. nov. 



Adult Female. — Length, from 7 to 16 lines, exclusive of the falces. The 

 length of the example described below is intermediate between these two 

 extremes — 12 lines. The cephalo-thorax is of an oblong oval form, truncated 

 at each end, the fore extremity being rather broader than the hinder one. 

 The thoracic portion is rather depressed, but the caput is elevated and 

 tolerably well rounded above. The normal grooves and indentations are 

 strong, esxDecially the one which marks the junction of the caput and thorax. 

 The ocular area is of a transverse oval form, slightly elevated and rounded ; 

 there are a few erect black bristles on this part, a single line of the same 

 along the middle of the caput, and some stronger curved ones on the clypeus 

 immediately in front of the ocular area ; one in particular being much longer 

 than the rest, more tapering, and somewhat sinuous. 



The colour of the cephalo-thorax is dark yellow-brown, thickly clothed
