 species in 129 bottles. All alcoholic insects received from the 

 Peabody Academy have been revised and arranged with the 

 general collection. 



About ten years ago a large part of the American Arachnids 

 were sent to Count E. Keyserling, in Silesia, who had agreed to 

 study and to publish them. As the collection sent to him has 

 been returned, it may be in place to enumerate his publications. 

 From 1877 to 1887 he has issued seven papers, " Neue Spinnen 

 aus Amerika," in Verhandlungen Wiener Zool. Bot. Gesellschaft, 

 containing 151 new species from North America. He has also 

 published a separate work in quarto, " Spinnen Amerikas " : 

 Vol. I., Laterigradse, 1880, contains 58, and Vol. II., two Parts, 

 Theridiidse, 1884 and 1886, contains 189 North American species. 

 All these publications are accompanied by plates, many of them 

 colored. A large part of the new species from North America 

 were sent from the Museum, which now contains the types.

 pp. 335 and pi. 12. He has studied the typical collections of 

 the Museum.
