below: these colours in the living animals, according to Mr. Barnard's 

 notes, are dark maroon red a hove, bright scarlet below. Those 

 from the unknown station are a trifle larger and are more or less 

 uniformly light dirty gray-brown: they are in rather poor condition. 

 Those from 11)38 range up to 45 mm. in length and are dirty cream- 

 colour; the body wall in these specimens is softer than, and the 

 colouration utterly unlike, that of the Saldanha Bay specimens, but 

 the calcareous particles seem to be identical. Comparing this material 

 with Thcel's description and figures has satisfied me that all must 

 be called imolens. Evidently in shallow water, pigmentation occurs 

 much more heavily than at greater depths, especially on the dorsal 

 surface.

 11 specimens; adult. 



Saldanha Bay: low tide lying exposed in pools with sea-weed.

Saldanha Bay; low tide, under stones. 5, IX, 1912, K.H.Barnard. 

 7 specimens; young. 



Locality unknown, but PIETER FAURE collection and probably from 

 off Cape Point. 23 specimens; young. 



CUCUMARIA CAPENSIS. 



Theel, 188(3. CHALLENGER Holoth., p. 62; pi. V, fig. 2. 



In the form of the body, the distribution of the pedicels, and the 

 firmness of the body- wall, this species approaches Ocnus and I was 

 inclined to refer the specimens before me to that genus, but on 

 comparing them with Theel's description and figures of C. ca/pensis, 

 I realized that they belong in that species. The PIETER FAURE 

 specimens are 16 and 38 mm. long, with a diameter about equal to 

 one-fourth or one-fifth of their length. The smaller one is light 

 gray but the larger one is nearly white.

The type locality for this species is Algoa Bay, but it seems to 

 be rather common along the eastern coast of Cape Colony and
