I collected it in large numbers, U.S.N.M No. 473940, under heaps 

 of leaves and branches in the Cacao plantation on the Annandale Es- 

 tate, August 25, 1929, and a small number, U.S.N.M. No. 390105, at a 

 much higher elevation at Granitown House, August 25, 1929. The 

 latter average a little smaller and stronger sculptured. Both of these 

 localities are on the western slope of Grenada. 



U.S.N.M. No. 57768 contains two specimens received from Bland ; 

 US.N.M. No. 366504 contains eight specimens, and U.S.N.M. No. 

 366503 two specimens from Vendryes. None of these lots bear specific 

 locality data, only the label Grenada, but all belong to this race. 



Ten specimens from the Annandale lot yield the following 

 measurements : 



Of the animal of this subspecies from the Annandale estate, my 

 notes say : "Dorsal parts pale rose color, sides a little paler, sole of 

 foot rose colored with a huffish tinge ; tentacles crimson."

Shell agreeing with typical A. {A.) grenadense greriadense 

 (Shuttle worth) in size and shape but differing from it in having the 

 sculpture of the spire a little less strong, while that of the base is 

 very much reduced. I found these characters common to the speci- 

 mens collected on the east slope of Grenada. My largest series, 

 U.S.N.M. No. 473942, was obtained in a cacao plantation under the 

 collected heaps of dead leaves and branches of Baltazar, August 25, 

 1929. My notes say of the animal, "Coloration the same as that of 

 the specimens obtained at the Annandale estate." 



I collected the type, U.S.N.M. No. 474038, on the estate of Dr. 

 Edgar deJ. McSween, one of my medical students now residing in 

 Grenada, and I gratefully acknowledge his helpfulness during my 

 sojourn there. The type has 4.3 whorls and its measurements are
