Ph. opilionoides. I have unfortunately not been able to obtain access 

 to Fourcroy's Entomologia Parisiensis". 



As Blackwall under his Ph. phalangioides , and Simon under 

 his Ph. opilionoides, Westring has under the spider before us errone- 

 ously cited Ph. opilionoides (Schranck), C. Koch. Many other authors 

 also have either united or confounded this last mentioned species 

 with Ph. nemastomoides C Koch, which is identical with the Ph. 

 pha'anyioides of Blackwall and most French writers, or Ph. opilio- 

 noides Westr. and Sim. I have above given the most important 

 synonyms for this last species; it may perhaps not be out of place 

 to do the same for the real Ph. opilionoides (Schranck), which I look 

 upon as identical with Aranea Plnchii Scop. , and to mention some 

 of the marks, whereby they may be distinguished. As regards my 

 description of the male's palpal clava, the following should be ob- 

 served. In both species the tarsal joint in c? is short and thick; 

 the almost globular bulbns is articulated to its extremity, and from 

 its outer side projects a coarse process ("procursus") directed for- 

 wards or parallel to the bulbus, dilated and truncated at its extre- 

 mity; the bulbus displays on the under side a strong, compressed, 

 forwards-curved claw ("uncus"), and immediately before it two smal- 

 ler "appendices", the anterior usually of a dark, the posterior of a 

 pale colour. 



Ph. phalangioides (Fuessl.) 1775 cephalothoracc testaceo-albicanti, macula 

 ma/jna sub-postica fusca , lined albieanti plerumque geminata; sterno plerumque 

 testaceo-albicanti, interduni fusciore et maculis clarioribus circumdato; maxillis 

 tMtaceis; palporum partis tarsalis procursu in $ apice levissime tantum et inae- 

 qualiter impresso vel sub-emarginato , non fisso, unco bulbi minus compresso, 

 versus apicem sequaliter angustato, margine ejus breviore sive acie sequaliter (con- 

 cavo-) curvata, appendice bulbi anteriore angusta, apice in angulutn sub-rectum 

 flexa, fere [""-formi — Long, corporis 6 — 7, ceplialothoracis c:a 2 millim.
