Spiders from the Solomon Islands. 469 



on the upperside of the abdomen immediately behind the 

 pedicle covered with yellowish-white hairs. 



Carapace as long as tibia of second leg measured along its 

 upperside, and as protarsus of fourth, slightly shorter than 

 patella and tibia of third. 



Legs : femur of first armed above with 3 — 2 — 3 spines ; 

 patella with 1 posterior spine ; tibia with 3 — 3 spines below, 

 2 in front, 2 above, and 2 behind ; protarsus with 2 — 2 below 

 2 in front, and 2 behind, all in the basal half: second leg 

 armed like the first, but with one dorsal spine on tibia; third 

 leg armed like the second, fourth leg like the second, but 

 with only 1 distal spine on the posterior side of the femur. 



Vulva consisting of an anterior transversely oval depres- 

 sion, followed behind by a somewhat quadrate plate consisting 

 of two halves, which meet and form a sutural junction 

 throughout the greater part of their length, and then diverge 

 where the two sclerites dip into the epigastric fold. 



^ . — The femora, coxse, and tibia3 of the legs duller in 

 colour beneath than in the female; the lower side of the 

 abdomen covered with bright fiery yellow hairs, with no 

 median black stripe. 



Legs much longer (c/. measurements), carapace a little 

 longer than the third tibia, a little shorter than the fourth 

 tibia, about two thirds the length of the second ; spine-arma- 

 ture of legs as in female. 



Palpal organ (see figure, PL XIX. fig. 8 a) ; tibial spine 

 slender and straiglitish. 



Measurements in 'millimetres. — $ . Total length 32 ; length 

 of carapace 14*2, width 11 ; length of first leg 54, of second 

 53, of third 38, of fourth 44 ; patella and tibia of first 21, of 

 fourth 15*5. 



(J. — Total length 27; length of carapace 14, width 11 ; 

 length of first leg 75, of second 73, of third 50, of fourth 57 ; 

 patella and tibia of first 38, of fourth 20. 



Loc. Ugi and New Georgia (type), obtained by officers of 

 H.M.S. * Penguin ' ; specimens also collected by Mr. C. M. 

 Woodford, probably in Shortland Island. 



This species certainly differs from P. ignicomus of L. Koch 

 (* Die Arachniden Australiens,' ii, p. 701) both in colouring 

 and in the structure of the vulva and of the palpus. The 

 type of Palystes pinnotherus of Walckenaer (Ins. Apt. 

 i. p. 565)^ from Port Jackson, I have not seen ; but the 

 specimen which L. Koch identified by that name differs 

 from P. speciosus at least in the form of the vulva (see 

 L. Koch, ' Arachniden Australiens,' ii. p. 703, pi. Ix. 

 figs. 3-3 6). In Keyserling's collection there is an immature 

 female, labelled P. pinnotherus^ from Brisbane.
