AUSTRALIAN OPILIONES. 37 



The palpi are palish yellow, banded with black ; the legs have the 

 femur, patella, and tibia darker and greyer, the tarsal joint being 

 quite light yellow. 



One specimen, which I take to be a female, is much lighter and 

 greyer above than the others, and on the under side pale yellow, 

 without the black bands on the palpi. The genital operculum is 

 more thickly covered with bristles and the .sternum is corrugated, 

 Avhereas in the others it is not. The spinous tubercles on the 

 segments are more in number (about 14). Otherwise there is 

 not much difference. 



As in Mr. Pocock's T. pectinatus from Tasmania, which this 

 seems to resemble more than Dr. Sorensen's T. bicarinatics from 

 Sydney, the dorsal carapace is decorated with longitudinal and 

 transverse i-ows of small round tubercles, forming ringed areas 

 smooth in the inside. There are four longitudinal and about five 

 transverse rows of granules, but no median longitudinal row of 

 larger granules. 



The very remarkable eye-bearing tubercle, rising and pointing 

 upwards and forwards from the front margin, is broadest at the 

 base, and tapers to a point at the anterior end. The eyes are 

 situated one on each side, about half-way from base to summit. 

 Just behind the eyes a pair of long, pointed tubercles jut out one 

 from each side. These are followed by three more similar pairs, 

 and the whole is topped by one median tubercle ending in a sharp 

 point. The intermediate space between these is filled up with 

 small granular and pointed tubercles. On the front edge of 

 the carapace on each side of the eye-tubercle are five spinous 

 tubercles. 



Between the last row of small tubercles and the first of the 

 rear segments is a pair of moderate-sized spinous tubercles rather 

 wide apart. 



On each of the rear segments is a ti-ansverse row of long 

 spinous tubercles, about nine in number in the males, but more 

 numerous (about 12 or 14) and not quite so large in the female. 



On the under side the coxpe of the palpi and fii^st and second 

 pairs of legs are profusely covered with granular tubercles, but 

 tlie 3rd and 4th coxse are granular only along their margins. 

 Each segment has a row of round tubercles rather larger than 

 the above. 



The soft mouth-parts of the inner end of the palpal coxa form 

 a very distinct upper jaw-, divided longitudinally into two parts. 

 The same parts of the coxa of the first pair of legs similarly form 

 the lower jaw, each part lying on one side of a soft median lip. 

 Coxa ii., on the other hand, ends in a flat chitinous piece, which, 

 turning forwards, clasps the mouth-parts, and would appear to 

 support and hold them together. 



Coxa iii. is similarly hard but black, a.nd the pair seems to 

 form " arculi genitales " on each side of the genital operculum 

 •and sternum. The end of coxa iv. is a narrow ridge of hard 

 black substance, a continuation of the sides of the triangular
