564 RKV. O. p. CAMBRIDGE ON NEW ARANEIDEA. [JuilC 19, 



The labium is similar in colour to the maxillse ; and is of a some- 

 what suhtriangular form, rouuded at the apex ; it is large in com- 

 parison with the size of the maxillae, its apex reaching very nearly 

 to their extremities. 



The sternum is large, heart-shaped, truncated at its anterior extre- 

 mity, of a yellowish colour, and clothed thinly with coarse hairs. 



The abdomen is short, broadest and rounded at its hinder extre- 

 mity. This part is prolonged into a kind of flap which bends down- 

 wards and underneath, so as totally to conceal the spinners, whose 

 number and form consequently could not be discerned. According 

 to Dr. L. Koch (Die Arachn. Austr.) the spinners of this genus are 

 two in number. The colour of the abdomen is of a darker hue than 

 the cephalothorax ; its whole surface is rugulose and clothed with 

 coarse, bent, spiny bristles and hairs. The example described was 

 much disfigured by extraneous substances, dirt and dust, accumu- 

 lated and retained by its peculiar curved bristly armature. 



A single example of this remarkable Spider was received some time 

 since from Ceylon, where it was found, and kindly forwarded to me 

 among many other Spiders, by Mr. G. H. K. Thwaites. 



The type of this genus is Australian ; and its close affinity to Ste- 

 phanojn's (Cambr.) is very evident. The discovery of a second spe- 

 cies, so nearly allied to the Australian one, gives another proof of a 

 similarity between the Ceylon and Australian Arachnids. Two other 

 forms common to these two regions are the remarkable genera 

 Amyde, Cambr., and Miagrammojies, id. Although nearly allied 

 to Cryptothele verrucosa, L. Koch, the present Spider may be easily 

 distinguished by a great difference in the relative size and position 

 of the eyes.

 Eripus auiNQUEGiBBOsus, sp. n. (Plate LVI. fig. 5.) 

 The cephalothorax is broad and round behind, and much con- 

 stricted laterally at the caput ; this latter part is elevated at its fore 

 part into two considerable conical divergent eminences, and has a 

 third eminence of a rather stronger and blunter form at the occiput. 

 The surface of the cephalothorax is granulose ; the caput is of a 

 reddish orange-yellow brown, suffused more or less on the sides with 

 dark red-bi own, in which colour it joins with the line of the thoracic 

 region ; the summit of the occipital eminence, as well as a stripe 

 running from it forwards, is bright yellow ; and the facies has three 

 dark-brown perpendicular streaks; the outer ones are somewhat 

 sinuous, the middle one straight ; the three eminences are furnished 

 with short bristly hairs. 



The eyes are in three transverse rows, 2, 2, 4'; the lower or fore- 

 most row is the shortest ; and the hinder one is curved, the convexity 

 of the curve being directed backwards. Those of the first row are 

 amber-coloured, and divided by rather over two diameters' interval ; 

 those of the next row are larger, and are placed in front of the base 

 of the two conical eminences on the caput, being separated by an
