MELAMPUS. 171 



margin e dextro superne subsinuato, turn fere stricto, intus serie profunda 

 plicularum brevium, confertissimarum munito, columellari calloso, albo? 

 subappresso. Long. 12, diam. max. 7 mill. Ap. 10 mill, longa, medio 2j 

 lata. (Pfr.) 



Remarks. This species is inserted with some doubt 

 among the American Melampi. Some immature speci- 

 mens found in Florida cannot be referred to any of the 

 other species I have enumerated. Having sent them to 

 Mr. Redfield, he writes me that they do not in any way 

 differ from immature specimens of Melampus Redfieldi, 

 which he has from Bermuda. 



The above description is from the Monograph of Auri- 

 culacea, p. 35.
