286 E. C. POLLARD. 



females are considerably larger than this, I am inclined to 

 regard the small females as not yet full-grown. 



Colour. — My observations as to the colour of this Peripatus 

 have been made entirely upon specimens preserved in spirit. 



The general colour of the body is a reddish brown dorsally, 

 with a diffuse longitudinal streak of a darker shade extending 

 down the centre of the back. The median dorsal line is 

 marked by a well-defined narrow band still darker in colour. 

 Ventrally the colouring is much paler^ being a light grey or 

 greyish yellow. The colouring of the legs on their dorsal and 

 ventral surfaces corresponds with the colours of the dorsal and 

 ventral body surfaces. 



The antennae are of a dark red-brown shade, with their 

 terminal enlargements much lighter, almost flesh-coloured. 



This colouring obtains, with slight individual variations, 

 for all the specimens with one exception. In this unique case 

 the dorsal surface is piebald, with a pale straw-colour and a 

 reddish brown. The brown is disposed as a broad collar, and 

 as two lateral bauds just dorsal to the legs; the band on the 

 right side, however, is only present in the posterior region of 

 the body. There is a white median line dorsally. The ventral 

 surface and the legs are pale yellowish white. The antennae 

 are dark red-brown, with their knobbed terminations pale 

 yellow or whitish. 



This specimen is small, and appears to be a young form in 

 which the pigment is as yet not completely developed, or it 

 may possibly be an abnormality. 



B/idges and Papillae of the Skin. — As in the other 

 neotropical species of Peripatus, the ridges of the skin are 

 continued right across the dorsal median line. 



The papillae of the ridges are arranged in a single file of larger 

 ones, or two or three smaller ones occur abreast. 



As in P. Edward sii (Blanchard), there are accessory ridges 

 extending across the dorsal median line, but not reaching far 

 on either side of it ; and also, as in P. Edward sii, the diagonal 

 lines which occur in the Cape species, breaking the surface 

 into lozenge-shaped areas, are absent.
