those eyes. All the thighs are destitute of spines, and only the two 

 posterior legs are on the tibiae and metatarsi armed with a somewhat 

 variable number of spines. The female's vulva is composed of two 

 small, dark, not very distinct, spot-like, rounded fovese. The pear- 

 or club-like, at the posterior side of the base tumid bulbus tapers 

 pretty rapidly from the middle, being continued into a much nar- 

 rower, almost linear portion or shaft: its compressed apex is obliquely 

 rounded, and provided with a projecting margin or brim, which extends 

 from the outer round about the inner angle and extends right across 

 the apex obliquely upwards and outwards to the outer side. In the 

 outer corner of the apex a very small, fine, crooked spine is per- 

 ceived (much shorter than the breadth of the apex); at the inner 

 corner there seems to lie a fine, curved, black spine under the 

 dilated margin (?). At the outer side, just where the bulbus begins 

 to taper, there is a strong, slightly upward-curved tooth, which at 

 the base on the upper side carries another very small tooth. 



D. maurusia. — The cephalothorax is shorter and broader than 

 in D. Cambridgii and D. rubicunda: the breadth of the clypeus in 6 is 

 about as great as, in ? considerably greater than the length of the 

 tibia of the l:st pair. The interval between the two anterior eyes 

 is about equal to the diameter of those eyes. Excepting on the 

 tibiae and metatarsi of the two posterior pairs, the legs have spines 

 on the thighs of the 4:th pair only: these thighs have above, imme- 

 diately at the base, two closely contiguous, short spines, and, at 

 least in the male, also 1 — 3 more spines above. The vulva consists 

 of a narrow, transversal, backward-curved, brown area, in which are 

 situated two oval, obliquely posited foveas. The form of the bulbus 

 is very peculiar: on the outer side, above the middle of its length, 

 it tapers suddenly, and has there a little protuberance or short tooth ; 

 the "shaft" is longer than in D. Cambridgii, and not straight as in that 

 species, but broken at an obtuse angle; the basal part of the shaft 

 is somewhat longer than it is broad, tapering a little downwards, 

 the inferior part or continuation is considerably narrower than, but 

 about as long as, the basal part, somewhat dilated towards the apex; 

 from the outward turned corner of the shaft there issues in an op- 

 posite direction from and in an almost straight line with its infe- 

 rior part, a coarse and strong, blunt process or heel which is slightly 

 narrower than this part. In the apex itself are perceived two curved 

 divergent spines, one in each corner; they are considerably shorter 

 than in JD. rubicunda C. Koch, not so long as the breath of the apex 

 of the bulbus.
