(Forty-five specimens). 

 (Twenty-five specimens). 



The Molluscan genera Persona and Pirula (a species of the latter 

 closely allied to P. investigatoris) and the Nudibranch Pleurophyl- 

 lidea were represented. Also the Echinoderm genera Cidaris, 

 Clypcaster and Zoroaster ; and the Pennatulids Vcretillum, Umhcl- 

 lularia, and Pennatula, all in great numbers.

(One specimen. Almost typical 

 but differs from the type in two 

 respects : {a) the spinelets on 

 the scales are longer, {b) the 

 barbels are minute. These two 

 characters, the reduction of the 

 barbels and the increase of the 

 spinelets, are the principal 

 features which separate M. mac- 

 rolophus from M. investigatoris. 

 This specimen goes somewhat 

 further along the same line of 

 variation),
