Rettss ') is an entirely different species of the genus Eru/one, for 

 which I propose the name E. perforata 2 ); a third species with the 

 same spe ific name is Lophomma enstatum Menge 3 ), which is identi- 

 cal with E. monoceros (Reuss) Westr. : see that species next page; 

 a fourth is Tmeticus cristaiu* Menge 4 ), of which see E. dentata 

 Westr. farther on.

2) The spider which I consider as identical with Ther. cristatum Reuss, and 

 which I call Erigone perforata , is distinguished even by its remarkable colours : 

 the cephalothorax , sternum and parts of the mouth are yellowish , the legs also 

 yellowish, but darker towards the extremity; the cephalothorax and sternum have 

 a narrow dark egde, and the abdomen is of a greyish black. The eyes are 

 placed in a large black area, from which three black lines go out and unite into 

 a blackish spot in the middle of the cephalothorax. In £ the thighs are yellow, 

 the patella whitish yellow, the following joints dark, but with the articulations 

 of a pale yellow tint; the black lines of the cephalothorax are slightly converging 

 behind; in <J the two outer lines, if present, are angularly curved, so as to include 

 a rhomboidal area : this area is somewhat elevated above the rest of the surface of the 

 cephalothorax and prolonged into an almost straight, short process resting with its 

 anterior extremity on the frontal part of the head, which is elevated into a nar- 

 row, rather high eminence. Seen in profile the pars cephalica thus shows itself 

 to be perforated with an oblong oval hole. The species appears to be nearly 

 related to Phalops furciUatus Menge (Preuss. Spinn., Ill, p. 220, PI. 43, tab. 

 120), but the process of the cephalothorax is not curved nor cloven at the extre- 

 mity; all the eyes are placed on the black front, the 4 superior (posterior) on its 

 more elevated, narrower portion. — Dr L. Koch has kindly furnished me with 

 specimens (from Nurnberg) of this interesting spider.
