PACIFIC SCIENCE, Vol. IX, January, 1955 
Bonnet (1951) has considered the question 
and decided that the name H. venatoria (Linn.) 
should be used. It was collected on all the 
islands under consideration. There is another 
very similar species, H. nobilis L. Koch, which 
is distinguishable most certainly by the sexual 
organs. An immature specimen from Raro- 
tonga might belong to this species. 
SALTICIDAE 
Bavia aericeps Simon 
19. Tokelau. Id 71 and 2 imm. Pukapuka. 
This species has a very wide distribution, 
ranging from the Marquesas and Hawaii to 
Malaya and the Phillipines. Compared with 
Samoan specimens these have a much paler 
abdomen, the same colour pattern being dis- 
tinguishable but only very faintly marked. 
Menemerus bivittatus Dufour 
19,2c?, and 2 imm. Tongatabu. Cosmopoli- 
tan and widespread in the Pacific. 
Plexippus payculli Audouin 
lc? and 2 imm. Tokelau. Cosmopolitan. As 
compared with Samoan specimens the longi- 
tudinal dark bands extend more posteriorly 
on the carapace and abdomen, and the femora 
are less dark. 
Sandalodes calvus Simon 
1 c? . Rarotonga. The species is recorded from 
Queensland and from the Marquesas and 
Tahiti, where it is common. Berland (1942) 
has commented on the interesting distribu- 
tion in the eastern Pacific. The present new 
record from Rarotonga appears to be its most 
western occurrence in this region. To judge 
from Berland’s figure (1933) its colour pattern 
is considerably paler than a specimen from 
the Marquesas. 
Ascyltus pterygodes (L. Koch) 
2c?. Tokelau. 2 9 imm. Tongatabu. 19,1c?. 
Niue. Recorded from many islands between 
the Marquesas and the New Hebrides. The 
Tokelau specimens are slightly paler than ones 
from Samoa. The chelicerae of the male from 
Niue are more robust, darker and much more 
hairy than those of specimens from Samoa, 
and the same is true of the other appendages 
to a slight extent. 
Athamas whitmei Cambridge 
1 c? • Tokelau. 1 c? . Rarotonga. 2 9 . Puka- 
puka. The species is recorded also from New 
Hebrides, Loyalty Islands, Samoa, Tahiti, 
Austral Islands, Mangareva, and the Mar- 
quesas. The specimen from Tokelau, as com- 
pared with ones from Samoa, Rarotonga, and 
Berland’s figure (1935) of one from the Mar- 
quesas, is paler. The carapace between the 
posterior eyes is dark blue while the rest is 
chestnut coloured, the abdomen pale with 
only faint markings. Femur I is pale brown 
on the pro- and retrolateral surfaces. The 
carapace of the Samoan specimen is almost 
black with blue iridescence, the abdomen 
dark except for the red patches, and leg I 
is dark on both surfaces. The carapace of the 
Rarotongan specimen is dark chestnut. Ber- 
land (1933) records that the colour is variable 
and two females from Hitikau in the Mar- 
quesas were almost black. 
Thorellia ensifera Thorell 
3 9, 2c?. Tokelau. 29, lc?. Pukapuka. 1 9 , 
2c?, and 1 imm. Rarotonga. This species is 
very widespread, from the East Indian Islands 
across the Pacific to Pitcairn and Henderson 
Islands. Berland (1935) figures a male in 
which the carapace is dark and the abdomen 
has a transverse zigzag. In specimens from 
Samoa the part of the carapace behind the 
eyes has a central dark streak, a dark margin 
and a horizontal dark band halfway between 
the eyes and the margin. The zigzag on the 
abdomen usually forms a broad transverse 
band. The Tokelau specimens are paler and 
the markings are scarcely discernible, whereas 
the others resemble the Samoan specimens 
except that the markings on the carapace of
