closed, thus confirming my previous observation in Pennsyl- 

 vanian specimens; but this character is apparently not constant. 

 Glochidia subovate, anterior, ventral, and posterior margins 

 forming a rather regular curve. They are somewhat higher 

 than long, but not quite so high as in Lea's figure (Obs. 13, 

 1874, pi. 21, f. 3). Length, 0.18; height, 0.20 mm.

NOTES. 



HELIX HORTENSIS FROM A MAINE SHELL HEAP. Dr. Glover 

 M. Allen, in company with Mr. James F. Porter, while exca- 

 vating in a shell heap on Great Spruce Head Island, Penobscot 

 Bay, found Helix hortensis at a depth of from one to two feet 

 below the surface, associated with bones of the large extinct 

 mink Mustela macrodon Prentiss. Although this mink has 

 probably not been extinct for any great length of time, the asso- 

 ciation of the two forms is another evidence in support of the 

 conclusion that the presence of H. hortensis in North America 

 is in no way associated with its settlement by Europeans. Mr. 

 Porter also found a fresh specimen! of H. hortensis near Duck 

 Harbor, Isle au Haute, Me., anew locality for the species.

C^CILIOIDES GUNDLACHI (PER. ) IN FLORIDA : In March, 1914 

 Mr. John B. Henderson sent me two bags of dirt gathered on 

 the south bank of the Miami River about two miles above Mi- 

 ami, and in it I found four specimens of the above species. 

 This may be the species collected by Bartlett in Florida many 

 years ago and called " C. acicula" by Binney ; Manual, p. 429, 

 as acicula has never been found there' ; ,by recent collectors. Pils- 

 bry, Manual of Conchology, second series, Vol. XX, p. 43, 

 states that the shells found by A. D. Brown at Princeton N. J., 

 "no doubt imported with West Indian plants," are gundlachi 

 although Binney recorded them in the Manual as acicula.
