relied upon for generic separation. In this view I have never 

 concurred for freaks occur even in the highest order of mam- 

 malia, without disturbing the status of its type. Still another 

 unexpected outcome of my investigation proves that our Ameri- 

 can species is not the designata of Hufnagel. 



Again through the helpfulness of Mr. Prout I was supplied with 

 the typical males of the forms of this European species, for it 

 seems that, beside the pink-banded form first described, their 

 other and more common form resembles in coloration our inter- 

 mediata Guen. I quote Mr. Prout in a recent letter : " The clear, 

 cherry red form with little black markings in the outer half of 

 the band, such as I found common at Toronto, and have received 

 from Maine is quite rare with us. Indeed, I have only one from 

 near London, which really matches them. I send you one fairly 

 bright and clear, taken at Epping Eorest, near London, and two 

 of the common forms (Essex and Germany)." 



The genitalic differences between these European forms do 

 not seem great, but as compared with our own, of which I have 

 made many mounts, there is a decided and constant difiference 

 in the shape of the chief determining parts, so much as to force 

 me to the conclusion that, called originally designata because of 

 its resemblance thereto, we have in reality another species in our 

 fauna, very constant in its coloring of gray, with central band of 

 bright Dutch pink, while the European pink form clings to the 

 brownish hue of its ally.

As long ago as 1857, Guenee (Spec. gen. X. p. 413) placed it 

 apart as his var. A, and calls attention to the fact that the discal 

 point is not present, and this is borne out by my entire series. As
