The present specimens exactly agree with the figure by A. S. quoted 

 above. I am sure I have seen the fine lines and further I have been able 

 to see the very fine transversal striæ (at least 25 in 0,01 mm.), so that 

 I am sure that this species really is an Amphora (compare GL Syn. II, 

 p. 141).
