 GENERAL NOTES. 



STATION OF LIMN/EA GRACILIS By a curious blunder. Reed s 

 Lake was said to be near Detroit instead of Grand Rapids, Mich., 

 in the February NAUTILUS, page 119. 



Canon A. M. Norman, in the "Annals and Magazine of 

 Natural History," for January, 1899 (page 79), gives an interest- 

 ing account of two recent specimens of the gigantic Madeiran 

 Helix Lowei Fer. This species, which attains a diameter of up- 

 wards of 2 inches, is not uncommon in the calcareous beds of Porto 

 Santo, but only two recent specimens are known : one collected by 

 Sr. J. M. Moniz some years ago, the other recently acquired by 

 Canon Norman, formerly in the collection of the late Baron von 

 Maltzan. 



CONULUS CHERSINUS var. DENTATUS. The toothed form of 

 Conulus was first noticed by Mr. W. G. Binney (Man. Amer. Land 

 bhells, p. 69). A note on the dentition of Conulus by Dr. V. 

 Sterki will be found in NAUTILUS VI, p. 10u.
