sis, and tin- majority <>f the other species of this genus, we ,-liall, per- 

 haps, prefer to regard the coloration as white with fawn bands, but 

 then \\e must admit that the uppermost band reaches the suture and 

 the lowest one the umbilicus, and that the unicolorous subvariety c 

 is produced by all the bands uniting together. The variation in the 

 number of bands is caused by the uppermost disappearing, and by the 

 fourth and tifth uniting into one. 



''This species, as regards the shell, bears some resemblance to 

 liiijiiniilux exflis Gmel. (guadelupensis Brug.), the type of the genus 

 Bulimulus ; but having examined the radula of <>. n/nlfn/tus. 1 have 

 found that it agrees better with that of UtnstniiniK, the median tooth 

 being also remarkably smaller than the neighboring ones" (v. Mor- 

 tens).
