1890.] NEW ARANEIDEA. 623 



at the extremities of the falces, but no spiny armature on the legs, 

 the position of the eyes, and the form of the claw-tufts, it may be 

 readily distinguished. A nest accompanied the Spider, but was 

 unfortunately too much damaged to enable me to do more than to note 

 that it was a round cylindrical hole, lined with white silk and covered 

 with a hinged lid or door somewhat between the cork and wafer types 

 in character.

In characterizing this genus {I. c. supra) the only materials avail- 

 able were a few fragments of the Spider, but as these comprised a 

 fore leg, a falx, the labium, and one of the maxillse, it appeared to 

 me sufficient to establish the genus upon. Subsequent examination 

 of a perfect specimen, as well as the characters given by M. Simon 

 (J., c. supra), have justified this opinion. A conjecture, however, 

 hazarded as to the affinity of this genus to Moffgrid(/ea, Cambr. 

 (based on the character and position of its trapdoor nest and some 

 points of structures), is not borne out. The position of the eyes, in 

 the perfect specimen which has since come under my notice, shows 

 that it is more nearly aUied to Idiops, Perty. There seems little 

 doubt but that it is identical with the Spider described by M. Simon 

 from Cayenne. 



Dendricon rastratum, Cambr. (Plate LIII. fig. 2.) 



An adult female. 



The cephalothorax and falces are of a pitchy black colour. The 

 legs rather paler, with an olive tinge. The abdomen is of a deep 

 purplish brown. vSpinners four; those of the inferior pair are 

 small and cylindrical, the superior ones short, two-jointed, upturned, 

 not visible when looked down at from above. Tlie relative length 

 of the legs is 4, 1, 3, 2, or 4, 1, 2, 3. The caput just at the occipital 

 junction is strongly prominent. 



The eyes are in two widely separated groups, two very near 

 together occupying a small prominence at the middle of the fore 

 extremity of the caput, the remaining six in a transverse oval figure 

 at some distance behind ; four of these six form a curved transverse line, 

 the convexity of the curve directed backwards, and a little way in 

 front are the other two, being the largest of the eight, and separated 

 (apparently) by rather less than a diameter's interval. The two 

 central eyes of the curved row are widely separated, and each is 

 about (or perhaps less than) a diameter's distance from the end eye 

 on its side. 



Another example, examined at the same time as the one above 

 described, may possibly turn out to be of a diflferent species, 

 though without further examination (which I am at present unable 

 to make) I hesitate to describe it as distinct. In this specimen the 

 general hue was yellow-brown, the proportionate length and breadth 

 of the cephalothorax seemed slightly different, the eves were more
