Alvania (Cingula) jan-mayeni 7 
As the Alvania jan-mayeni of Verrill thus is seen to differ 
from the typical Alvania jan-mayeni from the Norwegian and 
Polar Seas both as to sculpture and in biological respects, 
I fully agree with Friele’s view, that these two forms are not 
identical, and then it seems reasonable to retain for the 
North American form the name proposed by Friele, Alvania 
americana, as it is unreferable to any other species previously 
described. 
As refered to above Verrill’s first record of Alvania jan- 
mayeni is from the Gulf of St. Lawrence, in 366 m. Later 
on Whiteaves (27, p. 171) mentions that he obtained it in this 
locality in depths of 37 to $2 m. He says about the specimens 
taken: ,These were identified with Friele's R. jan-mayeni by 
Verrill in 1879, and before that year they had been referred to 
Rissoa scrobiculata Moller, on the authority of Jeffreys*. He 
further mentions that it is found fossil in the Leda-clay of 
Montreal. Whether this shallow-water form from the Gulf of 
St. Lawrence is identical with the deep-water form from the 
coast of New England, might, however, require a closer in- 
vestigation.
