MELAMPUS. 171 



margine dextro superne subsinuato, turn fere stricto, intus serie profunda 

 plicularum brevium, confertissimarum munito, coliunellari calloso, alboj 

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

 lata. (Pfr.) 



Remarks. Thi^ 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 Redfie/di, 

 which he has from Bermuda. 



The above description is from the Monograph of Auri- 

 culacea, p. 35.

 Melampus denticulatus Stimpson, is also identical with Alexia 

 myosotis.
