no TRAP- DOOR SPIDERS. 



pair of legs in the female are of even a more marked character in 

 the male, and hence they may be considered a good and tangible speci- 

 fic difference from other nearly allied species ; the tibise of the first 

 pair are considerably enlarged on the under side at the fore extremity, 

 where each is armed with a single, longish, strong, slightly curved, 

 pointed black spine directed forwards (fig. a, 3). ThQAbdomen'is small 

 and of an oval form ; its colours and markings resemble those of the 

 female, but on the hinder half of the upper side two or three indis- 

 tinctly traced pale angular bars or chevrons are formed by the dis- 

 tribution of the black-brown colours and markings; the under side of 

 the abdomen is of a uniform pale whitish yellow, except the spiracu- 

 lar plates, which are yellow-brown. The Palpi aro. moderately long 

 and strong ; the radial joint is longer than the cubital, and is of a 

 tumid and somewhat oval form, suffused over most of its surface 

 with dark brown, the rest of the palpus being of a yellowish-brown 

 colour ; the digital joint is small and somewhat oblong-oval, 

 curved downwards, and very slightly concave on its inside ; the 

 palpal organs consist of a nearly globular, basal, corneous bulb 

 prolonged into a strongish, curved, but not very long, pear- 

 stem form, the stem being distinctly cleft or bifid at its extreme 

 point {vide figs, a 1, and a 2), one portion of the bifid part is larger 

 than the other, thoiigh both are equal in length, and the stem of 

 the palpal bulb is directed transversely outwards, almost at right 

 angles with the digital joint. 



Until the discovery of the male spider noAV described, and which 

 is, without doubt, the male sex of the female described immedi- 

 ately before, this latter was thought to be the female of Nemesia 

 Manderstjerno} ( Ausserer), and it had indeed been so determined by 

 Professor Ausserer himself But the form of the palpal organs 

 diff'ers so decidedly from those of N. Manda'stjernce (Ausserer, 

 Beitrdge .... der Territelarice, Verhandl. Z. B. Gesellsch: Wien, 

 1871, Bd. xxi. p. 170), that all doubts as to the present being a 

 distinct (and as it is believed to be) a hitherto undescribed species, 

 are removed. From M. Ausserer's description, the pear shaped 

 stem of the palpal bulb in N. Manderstjernoi is comjjaratively 

 slender, ending in a fine and uncleft point, whereas, in N. Eleanora, 

 the stem is strong and its extremity cleft : other differences are 

 also observable in the two spiders, but this one is well marked and 

 the most tangible. 



The specific name, Elea)iora, now conferred upon the species, is 

 taken from the Christian name of the Hon. Mrs. Boyle, reference
