ordinary enoiigli, tlie profile line of the npper side forming a 

 tolerably regular convex curve. The height of the clypeus is 

 less than half that of the facial space. 



The eyes are of fair size and rather closely grouped toge- 

 ther. Those of the hind central pair are the largest, and are 

 separated by less than a diameter's interviil, each being still 

 closer to the hind lateral eye on its side. The four posterior 

 eyes form a straight line. The fore central pair, together with 

 those of the two lateral pairs, forming a strong and even 

 curved line, whose convexit}^ is directed forwards. Those of 

 the fore central pair are nearly contiguous both to each other 

 and to the fore laterals. 



The ahdumen is of a rather short-oval shape, very convex 

 above, and fits into the ])Osterior thoracic excavation ; it is of 

 a dark brownish-black hue, clothed with rather longer than 

 ordinary slender hairs. 



The spinners are short, compact, and of a yellow-brown 

 colour. The genital aperture (owing to some shrinking of 

 the adjacent parts) was not easy to make out satisfactorily ; 

 the figure given, however, is, I think, tolerably correct. 



This spider, whose remarkably excavated thorax has chiefly 

 induced me to found a new genus upon it, was kindly sent to 

 me from Nuremberg by Dr. L. Koch, by whom it was found 

 in that neighbourhood. 



Genus AYALCKENAiiEA, Bl. 

 Walchenaera antepenultinia, sp. n. (PI. XIII. fig. 3.) 



Adult male, length -^ of an inch. 



The Avhole of the fore jiart of this minute spider is yellow- 

 brown, the legs rather paler than the rest, and the abdomen 

 tinged with sooty brown. 



The cepkalofliorax is of ordinary form ; the lateral constric- 

 tion on each side at the caput is very slight, and the profile 

 line forms a pretty even curve to the fore ])art of the ocular 

 area ; the caput is thus not abruptly raised above the rest. 

 The height of the clypeus is less than one third of that of the 

 facial space ; and from behind each lateral pair of eyes a nar- 

 row somewhat three-cornered indentation runs backwards ; and 

 there is a curved (indented?) line close in front of the thoracic 

 junction. 



The eyes are small and form an area nearly as long as it is 

 broad at its fore extremity. Those of the fore central pair are 

 very minute, contiguous to each other, and (with those of the 

 two lateral pairs) form a cur\'ed line whose convexity is
