 but most notably in its much smaller size, the normal structure 

 of its arm tips, the shallower cuul somewhat more simple foveola 

 ornamenting the apex of the funnel groove (cf. fig. 5), and the 

 great development of the web bordering the arms which there 

 is nowhere exceeded by tentacle-like trabeculac

as follows 



Total length iiu-luding tentacles 1245 



Length excluding tentacles 1180

Width of mantle 162 



Length of fins (total) 330
