330 Mr. F. O. P. Cambridge on the 
(i.) Introduction. 
Tue following paper includes spiders of the group Ctenine, as 
well as others belonging to the 3-clawed forms of those which 
have the characteristic Ctenoid eye-formula. Of the new 
species, one was taken by Mr. 8. 8. Flower in Pinang, two were 
taken by Mr.C. W. Hose in Borneo, while a fourth was taken 
in Ceylon by Mr. W. Barnes. One new species occurred in the 
Keyserling collection and two more were found in the Museum 
collection. So far as the material at my disposal permits one 
to judge, there is no generic distinction between the 2-clawed 
forms found in these regions and those in Central, Equatorial, 
and Southern America. 
Of the 3-clawed forms, however, those included in my last 
paper on the genus Lycoctenus are quite distinct generically 
from those which Simon included under (7Zvéurius) Thalassius 
and Thorell under Dolopwus. One cannot refrain from 
remarking on the infinite trouble which authors are laying up 
for those that come after by publishing meagre descriptions 
of new species without any figures. Even in cases where 
descriptions are elaborately minute, there has in many instances 
been no attempt at selecting the salient differential characters. 
Unless the descriptions of authors are consciously comparative, 
numbers of characters common to a whole genus will be 
constantly repeated, while, as likely as not, the one vital differ- 
ential character will be overlooked, thus rendering the whole 
work useless and vexatious. 
Mr. R. IL. Pocock, of the Natural History Museum, has 
kindly allowed me to examine all the Eastern Cteniform 
spiders in the collection and describe the new forms,
