seen any P/io/c?<s-specimens from Carinthia, and cannot prove ray 

 opinion, I dare not now give this spider the name of Pholcus Phwhii 

 (Scop.), but call it Ph. opilioncrides (Schranck). 



The measures given by Schranck of his Ar. opilionoides , show 

 in fact that C. Koch has rightly identified that species. Hah.n's syno- 

 nym, on the contrary, is very uncertain; his figure and description 

 are certainly not taken from living specimens of the German Ph. 

 opilionoides, but from an old and badly preserved specimen of some 

 foreign Pholcus (perhaps Ph. phalangioides), which he confounds with 

 the former. 



Pholcus impressus C. Koch ') is in my opinion the male of 

 of Ph. rivulatus (Forsk.). The two forms are recognized, according 

 to Simon's description of the former and C. Koch's of the latter, by 

 the sternum being black (as is also stated by Savigny) and the belli/ 

 having a broad black central band. It appears to me also probable, 

 that Ph. barbarus Lucas 2 ) from Algeria is identical with Ph. rivu- 

 latus: in the female also of this latter form the sternum has a strong 

 conical protuberance behind — a feature which Lucas supposed to belong 

 only to the £ of Ph. barbarus. The male, or "Ph. impressus", which 

 C. Koch has described, is unknown to me; the female, of which I 

 have, through the kindness of Prof. Canestrini, received specimens 

 from Venice (under the name of Ph. impressus), and which I have 

 also myself met with in nothern Italy, is distinguished not only by 

 the above-mentioned protuberance on the sternum, but also by the 

 peculiar form of the palpi, which are thickened towards the extremity, 

 with the last joint almost pear-formed and pointed (just as in Ph. 

 barbarus, according to Lucas!). — Simon has (loc. cit., p. 121, PI. 2, 

 fig. 10) mentioned imperfectly developed specimens of a Pholcus 

 from France , which he calls Ph. grossipalpus, and the palpi of which 

 appear greatly to resemble those of Ph. rivulatus or impressus ?. 



A few words on the geographical distribution of Ph. opilionoi- 

 des and Ph. phalangioides may here be not out of place 3 ). Of Ph. 

 opilionoides (Schranck) nob. I have many specimens , which I have 

 collected partly in nortlacest Germany (Pyrmont), partly in Bavaria, 



to Germany the Austrian German provinces, but not those which by Prussia and 

 its allies have lately been torn from their northern and western neighbours.
