Abdomen: Length 1.18 mm, breadth 0.87 
mm. Spinnerets terminal. No noticeable chiti- 
nous plates. Epigynum as in Figure 8. 
Trite longipalpis Marples 
FEMALE ALLOTYPE: Afiamalu, Upolu, Samoa. 
2,200', collected by E. C. Zimmerman vi- 14-40. 
Length 7.72 mm. Color similar to male. 
Carapace: Length 3.77 mm, breadth 2.85 mm. 
Eyes: Ratios of the diameters of the eyes and 
of their distances apart: AM, 221; AL, 125; 
PM, 23; PL, 118; AM-AM, 27; AM-AL, 45; 
AL-PM, 150; PM-PM, 654; PM-PL, 144; PL- 
PL, 635. Breadth of eye-group 2.22 mm. 
Chelicerae: Simpler and straighter than those 
of the male. Promargin of the groove with two 
teeth as in the male. Retromargin with five 
teeth, the largest nearest to the fang and not 
separated from it by a concavity. Fang without 
the flange present in the male. 
Maxillae and lip: As in male, but the pit in 
the maxilla shallower. 
Sternum: Length 1.59 mm, breadth 0.89 mm. 
Palp: Long. Patella, tibia, and tarsus flattened 
dorsally, where they are somewhat darker in 
color and fringed with light hairs.

Abdomen: Length 4.41 mm, breadth 2.18 
mm. Epigynum as in Figure 9. 
MALE: In the males from Samoa the carapace, 
mouthparts, palps, and leg I are much paler 
chestnut-colored than in the type from Tonga. 
They correspond, however, in structure. A cor- 
rection to the measurements of the type are the 
tibial indices, which should be 8.8 and 7.2. 
Salticid 
A single mature male from Jarvis Island does 
not seem to belong to any species known from 
the Pacific area. It almost certainly must have 
been accidentally introduced by man and a few 
details and figures of the palps are given in the 
hope that it may be recognized. 
MALE: Length 4.9 mm. General color dark 
chestnut with very little abdominal pattern. 
Carapace broad and high. Chelicerae with two 
prolateral teeth, the nearer the fang being the 
larger, and one retrolateral tooth deeply divided
