Thd cqshalotkoraix h&s a bkck irregular patch on each aide of the 

 liinder part of the tlioracic region. The ocular region is eomewhat 

 HuffiiBed with blackish, and an irre^Iar black, somewhat V-shaped 

 marking indicates th« junction of the caput and thorax. The two 

 anterior pairs of legs have some black enffused markings on the upper 

 side of the femora, the fore half (or mther more) of the tibiiBj the meta- 

 tarsi, and tarsi of those two pairs being almost wholly black ; while the 

 two hinder pairs have only an irregular black marking here and there. 



The spines on the tibi® and metatarsi of the first and second pairs of 

 1^ aie numerous, long, strong, and conspicuous. 



The pale ones (mentioned aboTc) on the upper sides of the femora are 

 used, according to Mr, Forbes*s observations, to secure the spider on its 

 bock to a patch of whitish silk spun lapon the surface of a leaf. When so 

 secured the s]>ider has the exact appearance of the droppings of some 

 bird, and the white silk patch emerging irregularly outside the spider has 

 the appearance of the more liquid portion of the droppings flowing out 

 and drying on the leaf * 



The eye& of each row respectively are equidistant from each other, but 

 those of the fore-central pair form a shorter line than those of the hind- 

 central pair. The four ceatral Bjes form a square whose anterior side is 

 the shortest; and the height of the clypeus, which projects forwards, 

 is nearly about equal to half that of the facial space. 



The are, as described in the generic diagnosis, strong and niinutely 

 tuberculosa, the tibiio being of a peculiar bent form, 



A single example wiis found by ilv. Forbes in W, Java, and at a later 

 period a second on the Musi Ilivor, Sumatra, 



* Sir. Forlica has, since the above wna priDt(xlf Feniarkt-d to me that in the two 

 infitatiota which came under hie notice, the reeembbntTe tstende<l tveii to the 

 rnniiing down of the fluid excreta towartla the lower side of the Blupiiig leaf, 

 entUng in n kiuA of knob. Mr. Forb<a aim exproj^aly clisi laimed iht* vle& of 

 crediting the Bpitler with mj commmm tlesigti, but he saya that '"the simililud© 

 is no exnct, that the spider might hnve had ronsctousuees, and it cotild not have 

 been mort! esact if tho spidtr did have it.** Is not iU exactm probably tlie 

 nesnU of the tmconsciotujuesB of the spider? Conscious deeij^n would pnssibly

 Incietation.
