ARACHNIDA FROM THE SOUTH SEAS. 



By W. J. Rainbow, F.L.S , F.E.S. 

 (Entomologist to the Australian Museum.) 

 (Plate xxviii.) . 



Some months ago Mr. J. J. Walker, R.N., F.L.S., F.E.S., 

 kindly handed me a collection of Arachnid a for examination and 

 determination. The specimens were collected by that gentleman 

 during the island cruise of H.M.S. Ringarooma in the months of 

 June, July, August and September, 1900. Unfortunately my 

 study of the forms obtained was inter':'upted by illness, and the 

 publication of the results of Mr. Walker's labours delayed. 



In all Mr. Walker collected upon the various islands visited 

 thirty-four species, and these, with descriptions of new forms, are 

 enumerated below. It will be seen from a perusal of the list 

 that, with one exception, there is nothing but what one might 

 have expected. Some of the forms are common and widely 

 distributed.
