a a recent paper on the Pedipalpi of Ceylon (1910) I published 
- some notes on the habits of these curious creatures. Since 
this was written I have been able to inquire into their specific 
characters more fully than was then possible, and have in conse- 
quence to correct my identifications of some of the Tartarides. 
And further specimens of the long-armed form of the small jungle 
species of Phrynichus have now been obtained, which place beyond 
doubt its claim to rank as at least a definite variety. The object 
of the present paper is to supply correct identifications of the 
Tartarides, referred to in my previous one, which will involve the 
description of two new species, and to describe more completely 
this long-armed variety of Phrynichus pusillus. 
TARTARIDES. 
Mr. Pocock, when writing the Arachnid volume of the “ Fauna 
of British India and Ceylon,” was able to fit all the species there 
referred to into two genera, Schizomus, Cook, and Trithyreus, 
Kraep., following the classification adopted by Kraepelin in a 
volume of “ Das Tierreich.” He distinguished the genera by the 
width of the division of the posterior plate of the carapace, « 
character which [ found to be greatly affected by the method of 
preservation adopted. 
In 1905, several years after Pocock’s volume in the “ Fauna ” 
series was published, Hansen and Sorensen succeeded in getting 
together for study a very representative collection of Tartarides of 
both sexes from various localities in both hemispheres ; and together 
they published a monograph, in which the classification and specific 
characters of the tribe were dealt with by Dr. Hansen in a way 
that had never been possible before. In this paper the number of 
Species is extensively added to, but no additional genera are 
recognized. Indeed, the distinction between the old genera Schizo- 
mus and Trithyreus is regarded as of only sub-generic value. These 
sub-genera, moreover, are re-defined, so that the distinction between 
_ them comes to be not the actual width of the median suture of the
