HESIONIDAE 



Qi 



Remarks. The condition of this single example precludes a satisfactory examination. 

 It is a large specimen with 25 feet and measures 37 mm. in length. It seems to be very 

 close to T. levinseni. Southern, in the shape of the nuchal processes and in the very 

 wide insertion of the cirri : but the anal cirri are not spatulate. They are wider at the 

 base than at the end and the tips are bluntly rounded : they are supported by a hyaline 

 process. The collector describes the living individual as "semi-transparent orange."
