of Anabaena, Conferva, Oscillatoria, Spirogyra, Cladophora, Clathrocystis, Synedra, and 

 Navictda. To these may sometimes be added animals of polyzoan and protozoan groups. 

 A bibliography of 33 entries is appended. — F. C. Gates. 



595. Mangbnot, G. La structure des antherozoides des Fucacees. [The structure of 

 the sperms of the Fucaceae.] Compt. Rend. Acad. Sci. Paris 172: 1198-1200. 1921.— The au- 

 thor contributes to the discussion between Strasburger and others on the one hand and Guig- 

 nard and others on the other as to the nature of the sperm, the former holding that it is all 

 nucleus. The author inclines to the view of Guignard, finding that a large part of the tail 

 of the sperm is protoplasmic in nature, containing inert inclusions and pheoplasts, the latter 

 often in great numbers. The pigment spot is found to arise from the pheoplasts by the 

 development of carotin. — C. H. Farr. 



596. Mangbnot, G. Sur les "grains de fucosane" des Pheophycees. [On the so-called 

 grains of fucosanof the Phaeophyceae.] Compt. Rend. Acad. Sci. Paris 172: 120-129. 1921. — 

 It is decided that the grains of fucosan are neither the living organites of Crato nor the special 

 vacuoles of Kylin, but that they are simply vacuolar precipitates such as tannins and such 

 as occur in other groups of plants. — C. H. Farr. 



597. Pavillard, J. Sur la reproduction du Chaetoceros Eibenii Meunier. [On the re- 

 production of Chaetoceros Eibenii.] Compt. Rend. Acad. Sci. Paris 172: 469-471. Fig. 1-11. 

 1921. — Chaetoceros Eibenii belongs to the sub-genus Phaeoceros. A description and figures 

 are given of the auxospores and the endocysts in this species; these bodies have never before 

 been reported in this form. — C. H. Farr. 



598. Pavillard, J. Sur le Gymnodinium pseudonoctiluca Pouchet. [On Gymnodinium 

 pseudonoctiluca.] Compt. Rend. Acad. Sci. Paris 172: 868-870. Fig. 1-6. 1921.— This re- 

 markable organism belongs to the Peridineae. No chromoplasts but many small uncolored 

 plastids are found. Food is ingested. — C. H. Farr, ' 



599. Shaw, Walter R. Campbellosphaera, a new genus of the Volvocaceae. Philippine 

 Jour. Sci. 15: 493-520. PL 1-2, fig. 1. 1919. — The somatic protoplasts lack connecting fibers 

 and the gonidia migrate from the outside to the inside of the embryo. — Albert R. Sweetser. 



600. Tiffany, L. H. Algal food of the young gizzard shad. Ohio Jour. Sci. 21: 113-122. 

 1921. — One hundred and forty species and varieties of algae were found in an identifiable 

 condition in the digestive tract of the gizzard shad. These are grouped as Myxophyceae, 

 Euglenidae, Peridineae, Bacillariae, Desmidiaceae, Protococcales, and the filamentous 

 algae. — H. D. Hooker, Jr.

601. Allorge, a. p. Sur deux Sphagnum nouveaux pour la flore parisienne: S. laricinum 

 R. Spruce et S. Warnstorfii Russow. [Two species of Sphagnum new to the flora of Paris: S. 

 laricinum R. Spruce and S. Warnstorfii Russow.] Bull Soc. Bot. France 66: 406-409. 1919. — 

 A critical study of S. laricinum and S. Warnstorfii is given, their geographical distribution is 

 described, and the character of the moss flora of Paris is discussed. — A. Gershoy. 



602. Britton, Elizabeth G. The rediscovery of Physcomitrium pygmaeimi James. 

 Bryologist 24: 26. 1921. — The original description of Physcomitrium pygmaeiim was drawn 

 from scanty and immature material collected in Utah, but more abundant and better devel- 

 oped specimens have since been found in Nevada by C. F. Baker and in Alberta by A. H. 

 Brinkman. On the basis of these specimens the author gives a more complete description of 

 the species. [See also Bot. Absts. 9, Entry 878.] — E. B. Chamberlain.
