tin- head is paler than the rest of the dorsal surface. The orange of 

 the papilko is still recognisable after nearly a year. 



The effect of hardening agents and spirits of wine upon the colour 

 deserves notice. At first the green tinge gives place to a deep black, 

 only to reappear after the lapse of some months, and in course of 

 time the dark pigment becomes a more and more decided green. 

 Immersion in spirits for a few weeks or months further causes every 

 trace of orange and red to disappear. 



Locality. Under stones, logs, bark, and in rotten wood on the 

 slopes of Table and other mountains of the Cape Peninsula, and in 

 the Cedar Mountains, Clanwilliam. I have found this species in 

 the Platteklip Eavine on the Cape Town side of Table Mountain, 

 in the woods on the Newlands slope, and in ravines near Camp's 

 Bay and Hout Bay ; also at St. James and at Simons Town along 

 the False Bay coast. I have never met with it on Signal Hill, which 

 is the home of P. Iconina. 



I', balfonri was confused w r ith capciisis for a long time, until 

 Sedgwick separated it in 1885. In his original description this 

 author states that the larger papillae on the dorsal surface are white, 

 and that the eighteenth pair of legs in the male is hardly distinguish- 

 able from the large papillae found near the hind end of the body. 

 This caused me at first to consider the specimens described above as 

 possibly different from Sedgwick's balfouri (Trans. S. A. Phil. Soc., 

 ix., p. xviii, 1897), but I am now convinced of their identity, and 

 think it probable that that author's description was drawn up from 

 preserved specimens only. 



8. PERIPATOPSIS LEONINA, n. sp.* 



Characters. Claw-bearing legs 22 pairs in the types, 21 pairs in 

 other specimens ; the middle spinous pad very broad, 2 - 2-3 times as 

 wide as the proximal pad. 



The leg on each side of the genital opening as in balfouri in both 

 sexes. 



In the male the last praegenital pair of legs is also somewhat 

 smaller than the penultimate pair. 



The papillae on the dorsal and lateral surfaces shaped as in 

 balfouri. 



Length of large 3 (alive and extended): 34 mm. 



* These specimens are referred to by me in Trans. S. A. Phil. Soc., ix., 

 pp. xviii-xix, 1897.
