1908] Terry,— Lists of Connecticut 179 
The sum of these investigations is this: that one plant of Erica 
cinerea which it has been impossible to trace to human agency ap- 
peared in Nantucket forty years ago and lived till 1902 or 1903; that 
there are two of the same species of doubtful origin now alive near 
the spot where the first was found; that the Lawrence Coffin Cal- 
luna, now dead, in all probability adds one more locality for this as 
a wild plant to those previously known in New England and the 
British provinces; that the Calluna of the nursery came in from 
Europe with the imported trees; that every other bit of it on the 
island goes back to that for its origin, or else has come from the Kim- 
ball, Dahlgren or Starbuck seed, and that the cross-leaved heather, 
Erica tetralix, stays under the pines and larches where it was first 
found.

ADDITIONAL LISTS OF CONNECTICUT DIATOMS. 
WILLIAM A. TERRY. 
DuniNG the past year I sent to Tempére at his request some fifty 
different gatherings of North American diatoms. He was about to issue 
the second edition of the “Diatomeés du monde entier" ! and I was 
pleased at the opportunity of bringing these collections to the notice 
of the scientific world, especially as many of them contained new 
species that I had discovered. Among these gatherings was one 
from “Doers Mountain Grove" Ice pond, on a small mountain 
brook near New Britain reservoir. 'lhis was notable as contain- 
ing abundance of Surirella Terryi Ward. This Surirella was the 
principal form in Spring's Pond, a small pond on the north bank of 
the Pequaback River in Bristol, and with it were numbers of the 
small S. ovalis var. angusta (Kütz.) V. H. A quarter mile down the 
river just east of Saw Shop is a pond hole on the Lee property formed 
by cutting off a bend of the river when the highway was moved to ac- 
commodate the railroad; this is also rich in S. Terryi. Below this
