Plankton-type. This species occurs in the Mediterranean, the 

 Red Sea and the Indian Ociean. It is common in the tropical and 

 and subtropical Atlantic, at least from 26° S. to 50° N., and rare 

 specimens may drift towards Scotland and Iceland, even north of 

 Iceland (September 1898). Its principal area of distribution is 

 between Cape Verde, the Eng. Channel and New York. In 

 July and August 1898 it was seen between 40° — 50° N. across the 

 whole Atlantic. — S (D).

- Since the above was written I have been convinced that this species 

 is the same as T. bottnicus Nordq., or Lcprotintinnus boUnicus Jorgens., but 

 without foreign agglutinated bodies. The genus Leprotintinnus is thus inad- 

 missible.
