NOTES. 



In the May number of the NAUTILUS in an extract from Bulletin 

 49, Florida Agricultural Experiment station, the writer stated that 

 he did not know how long the ^Manatee snail (DrymoEus dormum") 

 had been living on orange trees in Manatee County. 



I lived in that county near Bradentown from 1882 until 1886, 

 and during all my residence there diligently collected the land, 

 fresh-water and marine mollusks of that region. During my resi- 

 dence there I collected Drym&us dormani in moderate numbers liv- 

 ing on the orange trees of a grove in hammock land west of Braden- 

 town, and rarely on trees in a grove north of Manatee river. I also 

 found a few specimens in the Foster Orange Grove south of Mana- 

 tee. I found several hundred dead shells in the heavy hammock 

 among live oaks north of the Manatee river, and rarely in the air 

 pines on live oaks elsewhere, but I never considered it abundant any- 

 where. 



It may be of interest to state that Mr. E. J. Brown, a neighbor of 

 mine, has found a few specimens of the nearly allied species (D. 

 dominions) living on his grapefruit and orange trees, and two or three 

 specimens of D. multilineatus on his trees. Drymczvs domlnicus is 

 rather a scarce species in this region. CIIAS. T. SIMPSON.
