the inner distal edge of patella of third leg with 4-9 stout apical 

 spinules ; the inferior surface of coxae of first leg generally entirely 

 without dentiform spinules, sometimes, how y ever, with a few weak 

 and inconspicuous ones confined to a narrow area in the basal half 

 of the posterior margin of the coxa, this area very much less 

 extensive than the large denticulate area on the coxa of second leg. 

 (In namaquensis the denticulate area on the first leg is almost or 

 quite as extensive as that on the second leg, and occupies almost 

 half of the inferior surface of the coxa.) 



Genital opercuhtm smooth for some distance in front of the hind 

 margin (in one specimen with a transverse groove near hind margin, 

 as in namaquensis). 



Measurements of largest $ . Total length 33 mm. ; length of 

 carapace 10, width 9 ; length of tibia of first leg 4i. 



Cocoons. The cocoons, of which 2 specimens were obtained, con- 

 sist of a white oval capsule, almost flat on one surface, but strongly 

 convex on the other, and of a tough parchment-like texture. The 

 oval edge of the flattened side is provided all round with a broad free 

 flap. I counted in one uninjured cocoon 89 eggs, measuring on an 

 average 2-4 mm. in diameter (in spirits). The flat side of this 

 cocoon measured 22 mm. by 13 mm., and its thickness was about 

 9-10 mm. The eggs occupy only slightly over half the inner cavity. 

 The embryos, which were preserved on December 1st, were already 

 considerably advanced. 



A J with a brood of young was dug up on January llth. 



Nests. The nests, with the surrounding earth of 4 of the speci- 

 mens, were sent to me by Mr. Schreiner, the dimensions being as 



follows : 



No. 9509. No. 9519. No. 9508. No. 9510. 

 Width of lid taken parallel 



to hinge 18 18J 21 24 



Width of lid taken at right 



angles to hinge 15$ 15 18$ 18$ 



Width of hinge 13f 17 16$ 19$ 



Width of hole at about 



20mm. from edge ... 10$ 12 15$ 16 J 



Average thickness of lid ... 2 2$ 3 3 



Length of occupant 20 19$ 26 27 



Width of its carapace 5J 6i 7f 9 



Although constructed on the same plan as those of Stasimopus, 

 the nests of Gorgyrella are easily distinguishable from those of that 

 genus.
