of a different species, though it agrees in most respects with the de- 

 scriptions given (/I.e.). The chief difference I can detect is in the 

 colour of the legs; but as this may differ considerably in examples of 

 different ages or in different states of preservation, it is not always con- 

 clusive on a point of specific identity. In the example now recorded 

 the legs are yellow, the greater part of the femora of the first pair as 

 well as lower part of those of the other pairs being suffused strongly with 

 brownish black ; the cephalothorax is deep reddish brown, becoming 

 black on the caput ; the sternum and labium are yellowish strongly 

 suffused with deep brown, the maxillee and palpi being dull yellowish ; 

 and the abdomen is of a uniform purplish black above and on the 

 sides, the underside being of a dull yellowish drab colour ; the legs 

 are furnished with short dark blackish brown hairs. 



In the description given of E. nitida by Walckenaer the legs are 

 said to be black, with a white ring at their base, and another of 

 greater extent at the base of the femora of the third and fourth pairs. 



Enyo expers, sp. n. 



Female, immature, length 1 line. 



The whole of the fore part of this Spider is of a brightish yellow 

 colour, the legs, palpi, and sternum being rather the palest. 



The cephalothorax is of a somewhat oblong oval form with little 

 or no lateral constriction at the caput ; its convexity also is very 

 moderate ; the clypeus, which equals in height half that of the facial 

 space, is very projecting. 



The eyes are in the ordinary general position : the two large fore 

 central ones are on a large roundish black patch ; and the three lateral 

 ones on either side are contiguous to each other and form a short 

 curved row on either side, the foremost eye being very nearly con- 

 tiguous to the large eye on its side ; the interval between the fore 

 central eyes is nearly an eye's diameter. 



The legs are not very long ; their relative proportion appears to be 

 4, 1, 2, 3 ; and they are furnished with hairs only. 



Falces not very long, but strong, conical, and vertical. 



Abdomen oblong-oval ; of a dull yellow colour, the upper part dark 

 rusty red, with several indistinct slightly angular pale bars or 

 chevrons on the hinder half. The spinners (apparently four in 

 number) are not easily discernible; but on either side of them is a 

 patch of deep rusty brown. 



A single example of this Spider (differing both in its general form 

 and colour from all others known to me) was found under a stone at 

 Alexandria in the month of April 18G4.
