The chief centre of inteiest in this remarkable spider is its 

 cephalothorax, represented by fig. 2, plate x., on which there are 

 several horn-like protuberances or prongs (seven in all) ; the 

 tubercular (central) ocular eminence is somewhat the largest and 

 strongest, is directed slightly forward, whilst in G. furcata it is 

 perpendicular ; in the specimen described in this paper, there are 

 in conjunction with the central ocular eminence and proceeding 

 from its base, two lateral "arms," distinctly, though in a much 

 smaller degree, elevated above the surface of the cephalothorax, 

 jutting out laterally, and directed slightly forward ; placed in 

 front, but in a somewhat lateral position, and at the summit of 

 the tubercular ocular eminence, are four eyes, arranged in two 

 rows, and these are the largest of the eight ; at the extremity of 

 each " arm " there are two minute eyes closely contiguous to each 

 other. 



The horn-like protuberances arranged along the middle of the 

 clypeus (with the exception of two) are exceedingly prominent, 

 and in addition to these the cephalothorax is furnished with rather 

 long coarse hairs. 



The abdomen of this spider gives the creature a most extra- 

 ordinary hirsute appearance. It is thickly clothed with long 

 hairs, and these are much longer and coarser than are those of 

 the cephalothorax. The legs, too, are also thickly clothed with 

 the same material, which project at right angles. 



The type specimen is in the collection of the Australian 

 Museum, to the Trustees of which Institution I am indebted, not 

 only for allowing me access to it, but also for their courtesy in 

 granting me permission to describe this extraordinary spider, and 

 enabling me to make those notes necessary for the production of 

 this paper.
