A CONTRIBUTION TO THE KNOWLEDGE OF THE SPIDER FAUNA 

 OF THE BERMUDA ISLANDS. 



BY DR. GEO. MARX. 



Little has been heretofore known of the spider fauna of the 

 Bermudas. Mr. Black wall described six species in the Ann. and 

 Mag. of Nat, Hist., 1868 ; and Prof. E. Simon, in speaking of the 

 Arachnida of the Atlantic Islands in the Annales d. 1. Soc. Entom. 

 de France, 1883, has none to add to the list of Mr. Blackwall. He, 

 however, alludes to the character of the Bermuda spider fauna as 

 appearing to be related to that of the Azores and the Canary 

 Islands. 



Lately, Prof. Angelo Heilprin, of Philadelphia, visited the 

 Bermudas and collected there twelve species, and by his kindness I 

 have been able to study this addition to the spider fauna of that 



region. 



Mr. Blackwall described the following species : 



1. Loxosceles rufescens, Luc. 



2. Epeira gracilipes, Blackw. 



3. Xysticus pallidus, Blackw. 



4. Salticus diversus, Blackw. 



5. Heteropoda venatoria, Lin. 



6. Filistata depressa, Koch. 



The collection of Prof. Heilprin contains the following species : 



1 . Uloborus Zosis, "Walk. 



2. Xephila clavipes, Koch. 



3. Epeira caudata, Hentz. 



4. Epeira labyrinthea, Hentz. 



5. Theridium tepidariorum, Koch. 



6. Argyrodes nephilce, Taez. 



7. Pholcus tipuloides, Koch. 



8. Dysdera crocata, Koch. 



9. Menemerus Paykidlii, Aud. 



10. Menemerus melanognathus, Luc. 



11. Heteropoda venatoria, Lin. 



12. Lycosa atlantica, now spec. 



Loxosceles rufescens, Luc, has been found in the "West Indies, 

 Central America and Florida.
