The spiders collected at the Straits of Magellan represent a new 

 and strange fauna, and, although on two former occasions collections 

 have been made in the same region and the material described, we find 

 in our material that seven out of the ten species are new to sciences 

 The three already described are Epeira flaviventris Nic., which has been 

 described by Simon from a collection from Cape Horn aud which was 

 originally described by Nicolet from Chili in Gay's Hist, fisicay polit. de 

 Chili. We find here also the Epeira labyrinthea Hentz. mentioned above. 

 It is hardly recognizable, for its color has greatly changed ; the dorsal 

 folium is nearly obliterated, only two lighter spots at each side re- 

 main, and the whole body is covered with a long and dense pubescence. 

 The third known species is the cosmopolitan form Latrodectus mactans 

 Walck., occurring, as it seems, everywhere around the globe below 

 a certain degree of latitude. The following is the list of species from 

 the Magellan Straits : 



Gregory Bay : 



1. Epeira flaviventris Nic. 



2. Latrodectus mactans Walck. 



3. Amaurobius frigid us sp. uov. 



4. Lycosa ornata sp. uov. 



5. Thanatus antarcticus sp. uov. 



6. Clubouia brevipes sp. uov. 



Sandy Point : 



7. Lycosa fuegiaua sp. uov. 



Sandy Point — Continued. 



ri. Linypbia iuagellauii sp. nov. 

 Latrodectus mactans Walck. 



c. Laredo Bay : 



9. Guyenna rosea sp. nov. 

 10. Epeira labyrintbea Hentz. 

 Lycosa fuegiaua. 

 Epeira flaviventris. 



The collection from the Galapagos consists, unfortunately, of only 

 ten species taken in the nine days the Albatross was present in that 

 region. These ten species are representatives of eight families and 

 therefore suggestive of a rich fauna. What a pity that more time could 

 not be spent in collecting at such interesting points; but we are glad 

 for the opportunity of a mere glimpse at the very interesting fauna of 

 that group of islands. 



The Galapagos Islands have been visited before, and H. M. S. Petrel 

 collected natural history specimens extensively in 1875. Among these 

 were the following seven Arachnida, which were described and deline- 

 ated by Mr. Butler in the Proc. Zool. Soc. Loudon, 1877: 



1. Audroctonus atnericus Liuu. 



2. Lycosa indomita Nic. 



3. Gasteracantba insulana Thor. 



4. Theridium caroliuuiu Butler. 



5. Latrodectus apicalis Butler. 



6. Epeira cooksouii Butler. 



7. Thoinisoides utrifonuis Butler. 



Of these, three are represented in our collection, viz, Gasteracan- 

 fha insulana, Epeira cooksonii, Latrodectus apicalis. Two more speci- 

 mens, previously described, were found among the species, viz: La- 

 trodectus scelio Thorell (the renowned "Katipo" of New Zealand) aud 

 Eeteropoda venatoria, a cosmopolitan in the equatorial aud tropical 

 regions.
