that of II is also enlarged. Vesicle without granules below, except just at 
the base. Pectinal teeth 15, the scape being devoid of teeth at the base 
posteriorly over a distance equal to about one- third of its length. 
Measurements. — Total length 94, length of carapace 15*8, breadth of 
hand 13, length of hand-back 9*8, length of movable finger 15-5, distance 
between median eyes and posterior margin of carapace 6. 
The male of 0. carinatus differs from that just described especially in 
the rectangular base of the scape of the pecten posteriorly, and in the 
spinulation of the tarsi. The female of carinatus is at once distinguished 
therefrom in the shape of the genital operculum.

The Kimberley Museum has specimens from Steynsburg (H. Hahn) which 
closely approach the variety austeroides. The last sternite of the male is not 
quite so smooth as in the type of that form. The upper surface of the hand 
is not s6 flattened as in austeroides, and the 2 accessory keels are very 
indistinct. The length of the hand-back is only a mere trifle less than the 
breadth of the hand. 
Opisthophthalmus latimanus natalensis, Hewitt. 
The Natal Museum has an adult male and female from Mfongosi, 
Zuiuland (W. E. Jones), which seem to be referable to this form, though the 
hand of the male is not identical with that of the type from Estcourt. 
Stridulatory lamellae absent. Pectinal teeth, M. 13-15, F. 12. Tarsi III 
and TV with only 1 spine inferiorly on the anterior side apart from those on 
the lateral lobe. Hand of male with a well-marked finger-keel, which is 
smooth and continuous throughout. Inner portion of upper surface almost 
smooth, having no visible granules, and only slightly convex, the secondary 
keels indistinct. Movable finger elongated in comparison with breadth of 
hand. In the female the finger-keel, though interrupted in places, is not 
broken up into granules even towards the base of the hand. Infero-medial 
keels of caudal segment I in the male almost completely obscured on the
