matophores ; there also seems to be a certain tendency to an arrange- 

 ment in zigzag lines in a transverse direction, most apparent on the 

 ventral aspect. There is a single series of chromatophores along 

 the medio-dorsal line, exactly overlying the gladius, which appears as 

 a translucent line beneath; 21 of the organs can be counted to the 

 point where the translucent area expands.

 preservation.
