IMRODUCTIOX. 



Mr. Gates has been kind enough to permit me to retain, for my 

 own collection, the duplicates of such species as I wished to possess. 

 Consequently not all the specimens of the species enumerated 

 are preserved in the British Museum. I ought perhaps to mention 

 that, in accordance with Mr. Oates's directions, I have set apart 

 for the Museum the tijpc's of all the new species, and one or more 

 specimens of all the others, both male and female when both 

 sexes were contained in the collection ; and whenever several 

 specimens of a species were represented, the greater part of these, 

 including the best and most interesting examples, were reserved for 

 the Museum. All have been determined and labelled by myself*, 

 and the places where they were found are noted on the labels. 

 Many species were represented by a very large number of specimens, 

 of which some have been reduced to mere fragments ; in such cases 

 I have not counted them, and their number is, in consequence, not 

 given in this Catalogue. 



Of all the new forms, and of several others, as also of the 

 hitherto unknown sex of some species, I have in the following 

 pages given detailed descriptions ; of most of the somewhat imper- 

 fectly known species I have at least given such descriptive notes as 

 1 thought necessary or useful. Of already well-known Spiders I have 

 generally given a diagnosis of the species when I have not already 

 described it in some of my former treatises on South Asiatic Spiders ; 

 of the remainder only the name and the localities where Mr. Oates 

 found his specimens are mentioned. Eeference to the author and 

 the publication where the species was first described is, however, 

 always given ; other synonyms are, for the most part, only added 

 in cases where they are not to be found in my earlier works, 

 especially " [Viaggio di Leonardo Fea in Birmania e regioni vicine. 

 II.] Primo Saggio sui Eagni Birmani " f, and " Studi sui Ilagni 

 Malesi e Papuani, parte i.-iv." % 



As to the system of classification followed by me in this work, 

 it is in the main the same as that proposed in my paper " On 

 Dr. Bertkau's Classification of the Order Aranece, or Spiders " §, 

 with the modifications introduced by myself in another treatise : 



* Except some specimens which were in such a condition that they could 

 not safely be determined or described.
