Specimen from Batjan. Total length 9, length of carapace 5.5, of palp Dior 
1* leg (to apex of tibia) 8.5. 
Specimen from Ternate. Total length 10, length of carapace 5, of palp 6.5, of 
1* leg (to tip of tibia) 9. 
Specimen from Tobelo. Total length 13, length of carapace 6, of palp 10, of 
1 * leg (to distal end of tibia) 13. 
Specimen from Soah Konorah. Total length 10, length of carapace 4.5, of palp 6, 
of 1* leg (to end of tibia) 8. 
Thorell has already pointed out the variability of this species with respect to the 
length of the palpi and first legs. 
Plexippus sinuatus (Dol.) 
Saltieus (Attus) sinuatus Doleschall, Acta Soc. Sei. Indo-Neerland., V, No. 5, p. 18, 
pl. III, fig. 2, 1859. 
Plexippus sinuatus Thorell, Ann. Mus. Genova, XIII, p. 240, 1878; id. op. eit. XVII, 
p- 603 (1881). 
Loc. Batjan and Oba in Halmahera. Several female examples. 
From Thorell’s table of distribution of Plexippus in the Austro-Malayan area (Ann. 
Mus. Genova XVII, pp. 708—709) it may be seen that the species under discussion has 
been recorded from the following localities: Ternate, Amboina, Sorong, Fly River (in Papua) 
and Cape York. 
The determination of Dr. Kükenthal’s examples is based principally upon what 
Thorell has said in 1877 respecting the form of the vulva of sinuatus. The description 
given of this organ in 1881 does not apply equally foreibly to the stucture. 
Plexippus kuekenthali sp. n. 
Pl. XXVI, figg. 26 a, b.
