at least exceed that of the humeral joint. The palpal organs are 

 well developed, prominent, but not very complex, with several promi- 

 nent corneous processes ; but these are of a less exaggerated nature 

 than in (Ecobius domesticus (Luc). 



The falces are small and weak, and, with the labium and sternum 

 (which are all of normal form), are similar in colour to the legs. 



The abdomen is oval and flattish above, but projects considerably over 

 the base of the cephalothorax, where it is somewhat truncate when 

 looked at from above and behind ; it is of a yellowish colour, clothed 

 with coarse hairs : on the fore half of the upperside is a dentated, lon- 

 gitudinal, central band, faintly defined by a dusky brown marginal line, 

 with a few other obscure blackish markings on the side of the fore 

 part and upperside of the hinder half ; some few white cretaceous spots 

 are also visible on the upper side ; the underside is of a uniform pale- 

 yellowish colour : the spinners of the superior pair are much longer 

 than the rest and turn upwards ; in front of the normal six there is a 

 transverse supernumerary one, or united pair : the anus has the pecu- 

 liar fringe of coarse hairs observed as yet only in this and the allied 

 genus Uroctea (Duf.). 



A single example of this species was found by myself on the 

 walls of my bedroom at the Hotel d' Orient at Corfu in May 

 1864. 



Family DYSDEEIDES. 



Genus Abiadke (Savigny). 



Ariadne ionica, sp. n. PI. XIV. fig. 2. 

 Adult male, length 3 lines. 



The whole of the fore part of this spider (except the labium and ster- 

 num, which are strongly suffused with dark brown) is of a brownish- 

 yellow colour, the abdomen being dull drab-yellow, strongly suffused 

 above with a warm reddish brown, but without (at least in the ex- 

 ample described) showing any pattern or design. 



The cephalothorax is oval, truncate before, very slightly constricted late- 

 rally in front, and rather flattened above, the caput and thorax being 

 of the same elevation ; it is (if any thing) a little darker in colour 

 than the legs, and is narrowly margined with dusky brown : the nor- 

 mal grooves and indentations are but slightly marked ; the surface is 

 glossy, but (apparently) marked thinly with small round punctures. 



The eyes are six in number, placed in three pairs very near the fore 

 margin of the caput ; those of the central pair are contiguous to each 

 other ; and those of each lateral pair are also contiguous to each 

 other, and placed obliquely on a tubercle, the two hind laterals being 

 in a straight line with those of the central pair.
