Falconer: Cornictilaria kochii^ Camb. 297 



spider is most characteristic. It is not only of a different shape 

 and much larger and stronger than in the other species, being 

 quite discernible in spirit with the unaided sight, but is. also 

 deeply divided at its extremity into two distinct, divergent 

 lobes, which are convex above, concave beneath, and curved 

 slightly downwards, with their edges ciliate with short, stiff, 

 straight, equal, pale-coloured hairs. The under surface of the 

 column is furnished towards the base with a number of longish, 

 stiff, irregular, spreading hairs. 



In C. ciispida Bl., the tubercle is simple and obtuse ; in 

 C. unicornis (fig. 7) and C. karpinskii Camb. (fig. 9), besides 

 being much smaller, it is only indistinctly bilobed at the apex. 



Palpus. The tibial joint is prolonged above in a very 

 large, long, irregular, curved apophysis, which is divided almost 

 to the base into two narrowly separated (latterly a little diver- 

 gent) portions, slightly unequal in length and directed forward. 

 The inner and longer limb, somewhat bent in the terminal part, 

 lies close to the digital joint, and is narrowed and slightly 

 sinuous towards the apex. Near the base on its outer margin, 

 it bears a strong tooth. The outer limb is further removed from 

 the digital joint, is abruptly acuminate at the apex, and sup- 

 pHed a little below that point with a stout, obtuse, oblong branch 

 directed downwards and outwards. The other males do not 

 possess the last-named process. 



In C. unicornis Camb. (fig. 6) and C. karpinskii Camb. 

 (fig. 8) the tibial apophysis is likewise divided almost to the 

 base. In the former, however, the limbs diverge, and the inner 

 one bears a tooth ; in the latter, the limbs converge, and the 

 inner one is without a tooth. In C. cuspidaia Bl. the apophysis 

 is undivided. 



The Palpal Organs are bulky, complex, and prominent, 

 the most noticeable features being (i) on the outer side at the 

 base, a stout dark brown C-curved process (fig. 5a) ; (2) at the 

 extremity, obliquely inclined outwards, a long, black, circular, 

 spine (fig. 5b) ; (3) on the inner side, springing directly from 

 beneath the apical spine, a long, strong, curved, red-brown 

 tooth directed backwards towards the base of the palpal organs. 



Eyes. Eight in number, rather small, the fore centrals 

 being decidedly the smallest ; arranged in two rows, which are 

 curved away from each other, enclosing an oval space. The 

 curve of the posterior row is very slight, that of the anterior 

 row is stronger. Both the hind and fore centrals are much closer
