It is a matter of no little interest that this little-known species 

 has been found by the PIETER FAURE. It was originally described 

 from specimens in the British Museum labelled "Cape of Good Hope", 

 and has not since -been met with. The three specimens at hand 

 agree well with Bell's description, but there are often 6, and rarely 

 7, arm-spines. In the largest specimen (15 mm.) the colored bands 

 on the arms are so faintly indicated as to be practically wanting, 

 while in the smallest (9'5 mm.), they are very marked; dull olive- 

 brown, conspicuously darker on both the proximal and distal margins; 

 in this specimen, the ground colour of which is pinkish-white, there 

 is a large blotch of pale brown on the disk. In the largest specimen, 

 one of the oral shields entirely lacks the supplementary plate, and 

 in one interradius of the smallest specimen, it is very small.

The species of Ophioderma described by Liitken in 1872 as tonga- 

 num under the supposition that it was from the Tonga Islands has 

 been recorded but once since, when in 1882, Lyman reported that 

 the CHALLENGER had taken it at the Cape of Good Hope, in Simon's 

 Bay, in 10-20 fms. As Liitken had but a single small specimen, 

 and its specific characters, were far from clear, it seems strange 

 that Mr. Lyman gives no information whatever about his specimen 

 or specimens. It is to be inferred however from his "Table of 

 Species of Ophiura" that he had several specimens and that they
