NO. 1 ziesenhenne: a new brittle star 3

Remarks. — This species is remarkably interesting because the 

 genus has a curious discontinuous distribution. There is one species 

 in Japanese waters, one in the East Indies and Tropical Australian 

 regions, one on the Southern Australian Coast, one in New Zealand, 

 one along the Central American coast and north to Southern Cali- 

 fornia, and now this new and particularly well-marked species from 

 the Galapagos and presumably endemic there. It is instantly recog- 

 nizable by the numerous plates on the upper side of the arm seg- 

 ments, their small size, and the closely fitted smooth pavement which 

 they form. More material may show that the coloration is also 

 distinctive.
