Taczanowski, is published in the ' Horae Societatis Entomologicse 

 Eossicse' (June, 1872). 



An important memoir on the Mygalidse (Theraphosse), in which 

 the species are distributed into forty-five genera, by Herr Ausserer, 

 appears in the Zool. and Botan. Ver., Vienna, 1871. 



The same author has also given descriptions of a number of 

 new spiders (Radspinnen), belonging to the genera Mastigosoma, 

 Peniza, Cyrtaphora, Singa and Zilla, in the same work. 



An extensive list of the species of spiders captured in Scotland 

 in the course of the last year has been published by Mr. J. W. H. 

 Traill, in the ' Scottish Naturalist' for the present month. 



A paper on the habits of some of the spiders of Madeira, by 

 F. Pollock, Esq., appears in the 'Annals of Natural History,' 

 October, 1872. 



Mr. A. Gr. Butler, the indefatigable Assistant in the British 

 Museum, has now extended his researches to the apterous groups 

 of insects, and has given a monograph of the genus Thelyphonus, 

 in the ' Annals of Natural History,' Sept., 1872. 



The same gentleman has also published descriptions of new 

 species of Myriopoda of the family Glomeridte, in the same

A very remarkable new genus belonging to the Thelj^phonidea 

 has been forwarded by Mr. Thwaites, the distinguished botanist

 lished by the Rev. 0. P. Cambridge, in the 'Annals of Natural

 appendages are also quite unlike those of any previous known 

 Arachnid.
