It appears to me probable tbat Walckenaer, when writing his 

 description of Lin. maxillosa, had before him specimens not only of 

 P. Clerokii, but also of P. Liste.ri. That P. Listeri is met with in 

 France is at any rate certain, for I have myself captured that spe- 

 cies at Versailles. In Sweden I have found it common at Satra in 

 Westmanland. — C. Koch had not seen this spider. — P. Listeri 

 differs from P. Clerckii, not only by its smaller size, but by having 

 shorter mandibles: they are only about '/ 4 — '/ 3 longer than their 

 greatest breadth , black or blackish brown , without tooth at the ex- 

 tremity in both sexes. In P. Clerckii on the contrary the length of 

 the mandibles is double their breadth ; they are yellow, with a shade of 

 red or brown, and are, in cf, armed with a strong tooth at the apex. 

 The vulva in P. LAsteri exhibits a small triangular brownish red 

 elevation, which is wanting in P. Clerckii, etc. — On the P. Clerckii 

 of Ohlert, see preceding species.
