are described. A new genus by Bubak is included of which he 
says: Besonderes Interesse verdient die neue Leptostromeceen- 
Gattung Kabatia von Lonicera xylostreum L. aus Tirol, welche 
eine schone Parallelform zu Leptothyrium periclymeni (Desm.) 
Sacc. darstellt. But the spores are two-celled, strongly curved, 
sickle-form; the genus belongs in the Scolecosporae. 
Die wirtswechselnden Rostpilze, Versuch einer Ge- 
SAMTDARSTELLUNG IHRER BIOLOGISCHEN VERHAELTNISSE VOn H. 
Klebahn, is a volume of 447 pp. issued in 1904 by Gebriider 
Borntrager, Berlin. This is a very important work bringing the 
extensive literature of this interesting subject together, neces¬ 
sarily incomplete however for the past year. The list of publi¬ 
cations cited (articles by each author chronologically arranged) 
includes an alphabetical list of 286 authors.. The General Part 
includes such topics as Begrifif des Wirtswechsels und Vorkom- 
men desselben, Entwickelungstypen, Spezialisierungserscheinun- 
gen, etc. The Special Part outlines the history and results of 
the various experimenters, species by species, beginning with 
Puccinia graminis. An alphabetical index is given of the heter- 
oecious species with their hosts, an Index of the Aecidia, and 
an Index of host plants. 
The genus Puccinia is discussed with reference to 
stability of nomenclature by J. C. Arthur in the Proceedings 
of the Indiana Academy of Science for 1902 (pp. 81-3). The 
name was used first by Micheli in 1729. Haller used the same 
previous to 1753 (initial date for priority), and again in 1768 
but here not employing binomials. Adanson cites the name in 
1763 but does not cite any species — hence the genus is not 
there established. The next oldest author for this name is 
Wildenow 1787 — giving the single species P. simplex, but the 
plant referred to was not a Rust; conclusion: perhaps Kuntze’s 
use of Dicaeoma is to be followed. 
H. W. Conn tells briefly, in the Fifteenth Annual 
Report of the Storrs Agr. Exp. Sta. (pp. 92-6), 1903, his 
results of extended studies on the Bacteria in freshly drawn milk, 
and points out the wide discrepancy between his work and that 
of Harrison and Cumming who found 95 per cent of bacteria 
belonging to the lactic types, whereas Conn detected less than 
50 per cent. Reports by the former indicate that the milk ducts 
furnish bacteria by thousands per cubic centimeter of milk, 
whereas Conn shows that the uncontaminated milk contains only 
small numbers. The discrepancies are referred to the use by 
Harrison and Cumming of ordinary gelatin.
