There is no perceptible folding of the valves in any of the specimens. 

 This species has been received with the label " T. japonica" and it is 

 likely that young specimens have been confused with that species 

 which is of the retusa type, while the present species leans toward 

 T. crossei. 



The reception of abundant material gives an opportunity for dis- 

 crimination between similar species which can not be afforded by a 

 few specimens.
