This species and G. Ganestrinii are undoubtedly the 

 most beautiful in the family ; G. palmifer, if not the 

 more beautiful, is probably the more remarkable of the 

 two. 



Colour. Very pale buff, delicately shaded with light 

 tints of purple and red ; where the light comes through 

 it the colour is almost yellow. 



Texture. Rough and granular, but still translucent. 

 On the cephalothorax the markings on the skin are 

 simply granular, but on the abdomen they are irregular 

 wavy or vermiform ridges or corrugations, the granula- 

 tion being a finer secondary marking. 



FEMALE (PL XII, fig. 2). 



Shape. Cephalothorax a very short wide triangle ; 

 abdomen almost square : the two are divided by a 

 well-marked line or fold just behind the second pair of 

 legs. 



The Palmate Hairs (PL XIII, fig. 3). These are 

 by far the most striking feature of the species, there- 

 fore I describe them first and separately. The body is 

 bordered by thirteen pairs (bilateral) of large and 

 elegant leaf -like hairs ; the corresponding hairs on the 

 two sides of the body are alike in form, but each pair 

 has its special shape, differing more or less from the 

 other pairs. Three pairs are on the cephalothorax and 

 ten pairs on the abdomen. Counting from the rostrum
