South African Species of Peripatida. 343 



Amongst the large number of specimens which I have examined, 

 those from the following localities deserve special notice : 



(a) About forty specimens from the wooded slopes of Table 

 Mountain at Newlands. It is characteristic of these specimens that 

 the dark-green pigment is very often (but not always) very faint or 

 quite absent between the dark-green papillas on the head, and some- 

 times almost the whole surface of the latter, including the papillae, 

 is quite white and devoid of all pigment. In some specimens a large 

 amount of orange-red pigment occurs, in addition to the colouring 

 matter which is always present in the orange papillae. This gives 

 the dorsal surface a decided reddish hue, while the lighter parts 

 (upper surface of head, ventral surface, especially of head) become 

 bright orange-red. In one very red specimen the greater part of the 

 head, however, was quite white in the living animal. In these red 

 specimens the ordinary green pigment is present in the usual 

 quantity. Orange papillae were never absent from the dorsal surface. 

 Professor Sedgwick appears to have obtained his specimens from 

 this locality. 



(b) About forty specimens from the mountain-side at Simons 

 Town. In these the dorsal surface of the head is always as darkly 

 pigmented as the rest of the upper surface. The ventral surface of 

 the body in the living animal is pale with a bluish or pinkish tinge, 

 that of the head orange-red. The orange pigment of the dorsal 

 surface is confined to the orange papillae, and is sometimes very 

 pale. In some specimens these orange papillai are partially or 

 wholly blackened in some parts of the body ; these form a transition 

 to the following : 



(c) Two specimens from a ravine on the mountain-side at St. 

 James (False Bay). In these all the papillae of the dorsal and lateral 

 surfaces are black, without any trace of orange.* Otherwise they 

 resemble the specimens from Simons Town. 



(J) A single female specimen preserved in spirits and found in 

 the Cedar Mountains at the Boschkloof Waterfall, near Clanwilliam, 

 by Mr. C. L. Leipoldt in November, 1897. The peculiarity of this 

 specimen is the presence on the outer surface of each leg of a small 

 number (two to four) of green-tipped orange papillae, similar to those 

 on the body. These are never found on the legs of specimens from 

 the Cape Peninsula, although in these the apices of one or two of 

 the papillae of the legs may occasionally be orange, owing to the 

 expansion of the central apical dot over the whole tip. The skin of 



* I was formerly inclined to consider these a new species (Trans. S. A. Phil. 

 Soc., ix., p. xviii, 1897).
