 (Proceedings of the American Academy of Arts and Sciences. 

 Vol. XXXVIII. October 1902. p. 89—99.) 



A list containing a single blue green, six grass greens, twelve 

 browns and twenty-eight reds, most of which are of wide distribution. 

 Glossophora galapagensis is described as new but seems more closely 

 related to Dictyota crenulata than to G. Kunthii, the type. Dasya Stan- 

 fordiana nov. sp. is described as resembling D. pacifica in its long 

 stichidia but differing in its long slender habit and in its branches den- 

 sely corticated to the apex. The name Hespophyllon is given provisio- 

 nally to a curious alga which in general appearance resembles Peysson- 

 nelia rugosa. but microscopically is quite different. Cystocarpic fruit 

 is unknown, but sporangia are formed abundantly from cortical cells.

Die Typhusbazillen zeigten sich ausdauernder, als man sonst wohl 

 angenommen hatte. Faeces eines Kranken wurden, nachdem sie fünf 

 Wintermonate in einer Grube gelegen, als Dünger auf's Feld (Lehm- 

 boden) gebracht; 15 Tage später wurden aus dem Boden in Platten- 

 culturen echte Typhusbacillen festgestellt. Hugo Fischer (Bonn).

The group is revised and divided into three genera; Ravenelia, 

 Pleoravenelia, and Neoravenelia. A general account of the group is 

 given and under each species is given the authority with the principal 

 references, description, host and locality, notes, and synonomy. IS spe- 

 cies are given in the genus Ravenelia, the following being new species: 

 R. slliquae on pods of Acacia farnesiana, R. fragans on Mimosa fra- 

 grans, and R. leucaenae on Leucaena sp. The new genus Pleoravenelia 

 has the following species; P. laevis (Diet. <& Holw.), P. similis n. sp. on 

 Brongniartia, P. epiphylla (Schw.), P. indigoferae (Transz.), P. brong- 

 niartae (Diet. & Holw.), P. talpa n. sp. on Tephrosia talpa. The
