color dark brown, covered with minute grey hairs ; the abdomen 

 comes up to the cephalothorax in such a way that the pedicle is 

 not seen. 



A single specimen of this species from Endeavour River, Queens- 

 land, in the Macleay Museum, was collected as an ant, and the 

 mistake was not discovered until the insect came into the hands of 

 its present possessor. This species is peculiarly interesting, as 

 coming close to the Ceylon species — S. bicurvatus and S. plata- 

 leoides — described by the Rev. O. P. Cambridge in the Annals 

 and Magazine of Natural History for January, 1860, and it is 

 another instance of close similarity in the araneides from Ceylon 

 and Northern Australia. In the plate the insect is represented 

 at four times its actual size. 



Gerrosoma Nov. Genus, a 



Cephalothorax entirely hidden by the projection of the front 

 part of the abdomen ; cephalic part pointed, elevated, and termi- 

 nating in a tubercle which carries six eyes. 



Eyes eight, unequal, round ; six, looking forward, placed in two 

 rows on the tubercle, two in the upper, and four in the lower row ; 

 the four centre eyes forming a trapezium, widest at the upper 

 part ; anterior intermediate eyes largest ; laterals very near to 

 these and smallest ; the other two eyes, placed in the angles of the 

 cephalothorax, directed laterally. 



Maxilla! broad, long, and diverging, rounded at the extremi- 

 ties. 



Labium much broader than long, convex, and rounded at the 

 anterior margin. 



Legs of two first pairs long, of two hinder pairs short, strong ; 

 1st and 2nd equal 1 and 3. 



Sternum oval.
