GREVILLEA. 



September, 1878. 



This number contains several lists of Fungi from California. 

 A new disease of the vine, known as Anthracnose, which appeared 

 during 1878 in the Narbonne district of France, was the subject of a 

 communication by Dr. Maxime Cornu, published in the Bulletin of the 

 Botanical Society of France, a translation of which is here given. An- 

 thracnose is caused by a fungus, which produces a circular black spot 

 with a white center upon the grapes, and corrodes or burns through 

 the stem even to the pith. It resembles Cladosporiu/n, but is much 

 smaller. At Etamps, the vine has been attacked by a fungus, probably 

 a Cladosporium. The development of both of these may have been 

 caused by the unusual rainfall of the year. An article on ChcetopJioina, 

 by M. C. Cooke, will be read with interest by students of Fungi. 

 Chcetophonia is the name applied to a number of small forms, which 

 may be the pycnidia of other known Fungi. A Proposal of Phono- 

 logical Observations on Mosses, by William Arnell, deserves at- 

 tention. The importance of the study of periodical phenomena need 

 not be insisted upon at this day.

 April— September, 1878. 



There are several articles in this number of interest to microscopists. 

 Dr. Joseph Leidy has found Aina'ba qiiadrilineata common in this 

 country, and, associated with it, Amceba verrucosa, which he believes 

 is merely the young of the former. He believes the forms Ama'ba na- 

 tans, Perty, Amoeba terricola, Greef, and Thecama;ba quadripartita- 

 Fromentel, to be the same as Amoeba verrucosa. A New Species of 

 Sponge, Aplysina pedicillata, Hyatt, probably from the East Indies, is 

 described and figured by Alpheus Hyatt. It measures from a foot to 

 sixteen inches in length, and not over one and one-eighth inch in 

 diameter. The walls of the tubes are composed of fibers of two kinds ; 

 the inner surrounds the tube, the outer consists of palmate extensions 

 of the inner sheet. The meshes are usually quadrangular, fibers hol- 

 low, the primary ones filled with debris. The sponge is referred to the 

 genus Aplysina, although it also possesses characters belonging to 

 Verongia and the true Spongiae. 



Prof. Leidy placed on record a number of synonyms and descriptions 

 of some new species of Rhizopods. The species belonging to Eugly- 

 pha, Trinema, Pamphagus, and Cyphoderia. A very interesting account 

 is given of some Amphipoda from mid-ocean, collected on the Pacific 

 by Surgeon W. H. Jones, U. S. Navy. ' The specimens collected are 

 fully described, and a plate accompanies the article. Several new 

 species were found, and a new genus, Calamorhynchns, was required 

 for one form. This genus is thus characterized:
