1 1860. Boott discovered echinospora muricata. 



1865. Boott rediscovered Tuckermani. 



1867. Boott collected echinospora Boottii. 



1878. Pringle collected echinospora robusta in Lake Cham- 

 plain. 



Engelmann also mentions other New England collections, but 

 they are not given in his list. After his time there is a hiatus in 

 publications, but collectors were accumulating undigested material, 

 and wrongly referring it often. The localities for Braunii have be- 

 come so numerous that it appears useless to enumerate them. 

 They occur in all of the New England States.

 borealis in Somes stream, Mt. Desert.

 ered it at Amesbury. I also found it at Kingston, N. H., and dis- 

 covered muricata at Kingston and East Kingston, where I found 

 the types of Eatoni and one specimen of Dodgei in a pond running 

 into Kingston. Graves collected Gravesii in Connecticut.

 lata, Eatoni, echinospora robusta, muricata and Tuckermani at 

 Epping, N. H., and the last at Nottingham. Dr. Graves collected
