1884.] NEW GENERA OF SPIDICRS. 201 



The above description (as well as that of Mr. Blackwall) has 

 been made from the type, still in my possession, received many years 

 ago from the East Indies, though from what locality there I do not 

 know. 



Ornithoscatoides ceylonica, sp. n. (Plate XV. fig. 3.) 



Adult female, length 5 lines ; in some examples the length is no 

 more than 4 lines. 



In general form and appearance this Spider nearly resembles the 

 two preceding species, but it differs not only in colours and 

 markings but also in several other important specific characters. 



The cephalothorax is slightly tuberculose, of a dull yellowish- 

 brown hue, distinctly and completely margined with cream-yellow, 

 from which some converging lines of the same colour run towards 

 the thoracic junction. 



The two central eyes of the posterior row are further apart than 

 each is from the lateral row on its side, and a similar observation 

 applies to the two central eyes of the anterior row. The four 

 central eyes form rather more nearly a square than the corre- 

 sponding eyes in 0. decipiens, the anterior side being proportionately 

 rather longer. The height of the clypeus is less than half that of 

 the facial space, and the laterals are not only seated on slight 

 tubercles, but between each of those pairs is a distinct spinous 

 tubercular prominence or short horn, terminating with a short 

 bristle. 



The falces are short, subconical, vertical, finely tuberculose in 

 front, and of a whitish cream-colour. 



The palpi are similar in colour to the falces, excepting the digital 

 joint, which is black-brown, blackest at the base. 



The legs aie moderately long, longer but less strong than in the 

 two foregoing species, though possessing the same essential cha- 

 racters and relative proportions. They are of a dull cream-colour, 

 the two fore pairs suffused or mottled above on the femora with pale 

 yellow-brown ; the anterior portion of the tibiae (which are strongly 

 bent), the metatarsi, and anterior part of the tarsi black ; at the base, 

 liowever, of the upper side of the metatarsi is an irregular whitish 

 cream-coloured marking, and the underside of that joint and of the 

 metatarsi also is more or less marked irregularly with a similar 

 colour. The spines on the tibiae and metatarsi of the first two 

 pairs are very long and strong ; the pecuhar ones noted as on 

 the upper side of the femora of the two foregoing species are 

 noticeable in the present one also. The two posterior pairs of legs 

 are more of a yellow-brownish hue marked with a paler colour, and 

 also with whitish cream-colour, giving them a somewhat annulose 

 appearance ; and there are some strongish spines on the tibiae and 

 metatarsi. The exinguinal (or basal) joints of the two hinder pairs, 

 and a portion of those of the second pair, have their undersides of a 

 deep rich brown colour. 



The sternum is of a deep rich black-brown hue, with a large patch 

 of cream-yellow at its fore extremitj'.
