A CONTRIBUTION TO THE KNOWLEDGE OF THE SPIDER FAUNA OF THE 

 BERMUDA ISLANDS. 



BY 

 DR. GEO. MARX. 



Little lias been heretofore known of the spider fauna of the 

 Bermudas. Mr. Blackwall 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 

 Soc. Entom. de France, 1883, has none to add to the list of Mr. 

 Blackwall. He, however, alludes to the character of the Ber- 

 muda 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 kind- 

 ness I have been able to study this addition to the spider 

 fauna of that region. 



Mr. Blackwall described the following species: 



Loxosceles rufescens, Luc. 



Epeira gracilipes, Black w. 



Xysticus pallidus, Black w. 



Salticus diversus, Black w. 



Heteropoda venatoria, Linn. 



Filistata depressa, Koch. 



The collection of Prof. Heilprin contains the following 

 species : 



Uloborus Zosis, Walck. 



Nephila clavipes, Koch. 



Epeira caudata, Hentz. 



Epeira labyrinthea, Hentz. 



Theridium tepidariorum, Koch. 



Argyrodes nepliilsc, Taez. 



Pholcus tipuloides, Koch. 



Dysdera crocata, Koch. 



Menemerus Paykullii, Aud. 



Menemerus melanognathus, Luc.
