Eriodon formidabile Cainbr. 



Eriodon formidabile Eev. 0. P. Cambridge, Journ. Linn. Soc, 

 Zool. vol. x. 1868, p. 260 ; L. Koc-b, Die Arachn. Austr. 187:}, 

 p. 454. 



This was described by Mr. Cambridge from an old dried speci- 

 men in the Hope Museum at Oxford, which had lost its palpi and 

 hind legs. He gives its length as 12| lines (or 26 mm.). 



There is a mutilated specimen in the National Museum of 

 Victoria, Melbourne, which I attribute to the same. 



It is very similar to E. occatorium both in colouring (dark 

 chocolate) and eyes. The front middle pair are very minute, about 

 four diameters apart. The eyes, which are all small, seem more 

 sessile, the front and rear rows about equal in length, and the 

 middle eyes of rear row nearer to the side-eyes of same than 

 to the front middle. Front row in a straight line. The whole 

 creature is larger than the foregoing, and the species are probably 

 distinct. 



Mr. Cambridge says his specimen had six spinnerets, which, if 

 correct, would make it differ from the rest of the genus. But old < I it 

 specimens are very difficult to handle and apt to be deceptive. In 

 the female I examined the rear half of the abdomen was destroyed. 



Localitif. Swan Hill (Eiver Murray), Victoria. 



Eriodo>" crassum Cambr. 



Eriodon crassum Eev. O. P. Cambridge, Journ. Linn. Soc, Zool. 

 vol. x. 1868, p. 269 ; L. Koch, Die Arachn. Austr. 1873, p. 456. 



This again is very like E. occatorium (sec. Cambr.), but smaller, 

 7| lines. The front side-eyes twice the diameter of front middle. 

 Legs 4, 3, 2, 1. Eemale from Swan Eiver, W. Austr. (Hope Mus., 

 Oxford). 



The specimen in Brit. Mus. labelled as E. occatorium ?, men- 

 tioned above, has the 1st, 2nd, and 3rd pairs of legs all about equal 

 length, but, coming from the same locality and in other respects 

 agreeing with the description of this species, I think it must be 

 taken to be the same. 



Eriodon granulosum Cambr. 



Eriodon granulosum Eev. O. P. Cambridge, Journ. Linn. Soc, 

 Zool. vol. x. 1868, p. 268 ; L. Koch, Die Arachn. Austr. 1873, 

 p. 455. 



Male. Length 7 lines. Swan Eiver, W. Austr. (Hope Mus., 

 Oxford), sec. Cambridge. 



Cephalothorax black above and below, as also legs and palpi. 

 Eves, as drawn, very similar to those of E. crassum. Ealces as long 

 as cephalothorax. strong black spines at upper extremity. Legs 

 long, 4, 3, 2, 1, « ith black hairs; black spines on underside of meta- 

 tarsi and tibiae. Margin of cephalothorax and caput rough and 

 granulose (a common feature in males of this genus). Male palp 

 with a double bulb and stigma of about the same length. 



This reads very much like the male of the preceding.
