BOOTT, DE CARICIBUS. 



female scales. Specimens exactly agreeing with the usual 

 typical forms of the C. ampullacea' of Europe were found by Dr, 

 Richardson in Arctic America. I have not seen any like them 

 from the States of the Union. They no doubt will be met 

 with ; but I think taking the types of either, few botanists 

 will doubt their specific difference. I have ventured to quote 

 the C. bullata, var. loevirostris of Fries, found near Chris- 

 tiana in Norway by Blytt, a specimen of which I saw in 

 Herb. Tuckerman, under C. utriculata. It cannot possibly 

 be considered as a form of C. bullata, and it agrees with 

 C. utriculata in having the lower female scales aristate. The 

 fig. of Schk. is conclusive as to C. bullata, from which 

 C. Tuckermani is clearly distinct.
