18/6.] REV. O. P. CAMBRIDGE ON EGYPTIAN SPIDKRS. 547 



M. Simon (Les Arachnides de France, ii. p. 5) states that U. du- 

 rundi, Walck., is also found in Egypt ; I did not, however, meet with 

 it myself there, though I found it shortly afterwards in the crevices 

 of old olive-trees at Corfu, whence it could only he extracted by 

 inserting a piece of stick, jagged at the end, into the crevice, and 

 twisting it into the strong silken nest, when the whole with its 

 occupant could now and then be drawn safely out.

Several examples which, after careful examination, I believe to be 

 of this species, were found under stones at Alexandria in April 18G4. 

 None of these^examples were adult ; this determination, therefore, 

 cannot be considered absolutely certain, since there are several nearly 

 allied species, such as D. crocota, C. Koch, and D. maurusia, Thor., 

 of which the immature examples appear almost to defy certain de- 

 termination. 



Gen. Oonops, Templeton. 



Oonops scutatus, sp. n. (Plate LVI1I. fig. 2 a.) 



Adult male, length 1| line. 



This Spider is very closely allied to Oonops loricatus, Sim. ; it is, 

 however, larger, the measurement of that species (taken from two 

 examples kindly sent to me by M. Simon) not exceeding three 

 fourths of a line in length; the abdomen of the present spider is 

 also of a rather narrower form, but more convex above, and far more 

 glossy and polished on its upper surface, while in colours and some 

 other characters there is but little apparent difference. 



The cephalothorax is oval, strongly constricted laterally at the 

 caput; the thoracic junctional point is (looked at in profile) of an 

 angular form, and elevated above the level of the rest of the cephalo- 

 thorax, the hinder slope being abrupt ; it is of a bright orange- 

 brown colour ; and the sides and hinder part are thickly covered 

 with minute tubercles or granulosities, which in some positions assume 

 the appearance of punctures. 



The eyes are large, six in number, closely grouped together, and 

 occupy nearly the whole of the upperside of the fore extremity of 

 the caput, where they form a quadrilateral figure whose foremost 

 side is considerably shorter than the hinder one ; they do not differ 

 much in size, and are all of a more or less oval shape ; those of the 

 hind central pair are closely contiguous to each other, their sides of 

 contact being flattened and so closely joined as almost to conceal the 

 junction. The eyes of each lateral pair are very near together, but
