The first species recorded by Demetrio, Ephemerum crassinervium, may be 

 E. spinulosum, and, if either, is not the species collected at St. Louis by Drum- 

 mond. 



Demetrio gives two species of Phascum in his list P. bryoides pilifera Schultz 

 and P. piliferum Schreb., but the former I have been unable to locate in the 

 Paris Index. In 1891 Demetrio collected P. cuspidatum americanum R. & C, 

 which he does not give in his list, and it may be that the first species of Phascum 

 of his list, or both species, belongs to this new variety. 



Demetrio lists Microhryum Floerkeanum, determined by Cardot, which 

 seems to me to be only another collection of Phascum cuspidatum americanum. 

 Two species and one variety of Dicranum are given in the list — D. fulvum, D. 

 scoparium, and D. scoparium orthophyllum. The first named may have been 

 determined by Cardot as D. fulvum, but in 1896, eleven years before Demetrio 

 published his list, Cardot described this collection as D. subfulvum, which Dem- 

 etrio neglected to list. D. subfulvum may not differ in any way from D. fulvum, 

 but not having seen the type specimens I can not say. D. scoparium is very 

 rare in Missouri, if not wanting altogether, and the variety orthophyllum listed 

 by Demetrio may be an error of determination, for the Paris Index does not give 

 this variety for North America. 



One species and a variety of Ceratodon are given in this list, C. purpureus 

 and C. purpureus aristatus. The specific form is common all over the State on 

 clay banks, but the variety cited dees not occur west of New Jersey. There is, 

 however, a variety that has been found in Missouri, C. purpureus xanthopus, 

 and, if Demetrio 's specimens are not the specific form, I think they may belong 

 here. 



The rare little Physcomitrium immersum, collected by only one other collector 

 in Missouri, was recorded by Mrs. Britton as collected at Emma, Mo., in 1894, 

 thirteen years before Demetrio published his list, but he must have overlooked it. 



Six species of Brachythecium are given in Demetrio's list, but one more might 

 have been given, for B. oxycladon dentatum is recorded as collected by Demetrio 

 in 1897, ten years before he published his list. 



No species of Bryhnia is given in Demetrio's list, but B. graminicolor Holz- 

 ingeri is credited to Demetrio in 1898, nine years before the publication of his 

 list.

CORA H. CLARKE

Through the death of Cora Huidekoper Clarke on April 2d, last, the SulH- 

 vant Moss Society has lost a member so devoted and of such long standing, that 

 more than passing comment seems called for. 



Miss Clarke was the daughter of the Rev. James Freeman Clarke, and came
