74 ON SOME RARE ARACHNIDS 



APPENDIX 



Mr. Bagnall sent to me in December, 1907, four examples 

 of an interesting Arachnid which he obtained in a hot con- 

 servatory at the Botanic Gardens, Kew. I imagined that 

 these might be Tartarides, so applied for assistance to 

 Professor H. J. Hansen of Copenhagen. He most kindly 

 sent me his monograph of the group.* Subsequently I sent 

 him one of the specimens, and he stated that although closely 

 related to Trithyreiis Camhridgii (Thor.) it belonged to an 

 undescribed species. It was then too late to figure it in the 

 present paper, but I resolved to describe it in an appendix, 

 and hope to publish figures soon. Unfortunately all the 

 specimens were females, and in this group the males are much 

 more distinct from one another than are the examples of the 

 former sex. I hope soon to obtain males from Kew. In 

 January, 1908, Mr. H. Donisthorpe sent a female of the 

 same species obtained by himself at Kew to Mr. Cambridge. 

 This Mr. Cambridge sent to me, and it is undoubtedly con- 

 specific with Mr. Bagnall's examples. It too is a female. 

 The Tartarides are a small group, only fifteen species being 

 previously known. They are related to the long-tailed 

 Thelyphonidea. There is only one family known — the 

 Schizomoidas (Hansen). This is divided into two very 

 similar genera, Schizovms (Cook) and Trithyreus (Kraepelin). 

 The Tartarides are not indigenous to Britain or Europe. 

 They have been found in California, Venezuela, West Indies, 

 Sierre Leone, the Seychelles, Ceylon, Burma, Singapore, 

 Malacca, the Philippines, New Guinea, and New Britannia. 

 T7-ithyreus Cambridgii (Thor.), to which the present species is 

 closely related, was found in Burma. 



Genus TRITHYREUS (Kraepelin) 



The second thoracic tergite shows a longitudinal, median, 

 membranous suture. The flagellum (or tail-like appendage of 

 the abdomen) is three-jointed.
