on inner side at base; beyond its apex are two short spurs lying close together, their points 
directed outwards. 
Vulva as broad as long, convex; a black corneous margin encloses a transverse oval 
pale space, including a low convex tuberele on each side, and converges behind forming a 
narrow transverse plate, curving downwards. On each side of this plate is a corneous denti- 
form process, its point directed outwards.

The figure of the vulva and pedipalp of this large and handsome species will render 
the identification of either sex camperatively easy.

This form is similar in every respect to kuekenthali save in the form of the vulva. 
2. Total length 12.5 mm. Carapace 6 mm. Legs 4, 1, 2, 3. 
Proportion of leg segments the same as kuekenthali. 
Vulva. Longer than broad, basal lateral margins uniformly rounded, not projecting, 
narrowed posteriorly with a pair of minute pits at the apex; the vulva presents anteriorly 
a low convex protuberance on each side. 
Lec. Minahassa (Celebes). A single 2 example. 
Whether this form is merely a variety of kuekenthali or not I cannot say, but in view 
of the different form of the vulva one would not be justified in describing it as identical. 
Possibly a long series would confirm my suspicions that there may be intermediate forms.
