Show 426 MR. H. R. HOGG ON AUSTRALASIAN SPIDERS. [Dec. 2, The front row of eyes is slightly procurved, the medians one diameter apart and slightly more from the side-eyes, the same from the margin of the clypeus, and more still than that from the rear median. The front side-eyes are clearly larger than the median. The rear row of eyes are equal and a little smaller than the front median, the middle pair two diameters apart and nearly three from the side. On the underside of the falx-sheath are two very large, one median and one small tooth, one large and one small on upperside. The legs are rather stout, and furnished with long and powerful spines on tibia iii. and iv., one each. The abdomen is ovate, broadest one-third distance from front and tapering to spinnerets.

Australia by Dr. Magarey in 1880. One female, and one male not fully developed, in Brit. Mus. from Port Stephen. N eosparassus th o r a c ic u s , nov. sp. (Text-fig. 87.) This powerful spider I provisionally include in this genus, with which and with Thelcticopis and Isopeda it has analogies, but differs in the shape of the cephalothorax; I think it ought to have a new genus but that it partially links the others. The cephalothorax is red-brown, black-brown in front; mandibles, lip, and maxillae black-brown, sternum and coxae bright red-brown ; legs and palpi somewhat darker, with long brown hair; the abdomen dark brown above and below. The cephalothorax rises steeply from the sides, is highest posteriorly and slopes forwards to the eye-space, it is 2 mm. longer than broad and broadly truncate in front. The front median eyes are about 1| diameters apart, rather more from the rear median, one diameter from the laterals, which are clearly smaller. The clypeus is wider than the front median eyes. The rear row is procurved, the median eyes wider apart than from the laterals, which are about the same size as the front laterals, the median somewhat smaller. |
