The perfect form has been obtained from various fungi with Fusaria- 

 Hke spore forms. They belong to such genera as Gibberella, Nectria, 

 Hypomyces, Calonectria and Neocosmospora. But the conidia of these 

 ascomycetes have not sufficient relationship to Fusaria Avithout known 

 perfect form to justify identification with any species of Fusarium sec- 

 tions, such as elegans, discolor, martiella, roseum and gibhosum. 



In neglecting such facts we would be exposed to a pitfall in the fol- 

 loAving case: Fusarium, culmorum W. G. Smith {F. rubiginosum App. 

 & Wr.) has conidia looking so much like small conidia of Gibberella 

 Saubinetti (Mont.) Sacc. that they seem to be identical. The former, 

 however, develops chlamydospores and no perfect form, the latter no 

 chlamydospores but the perfect form under culture conditions. If we 

 overlook this we may conclude after having proved one strain to have 

 Gibberella perithecia, that we also have proved F. culmorum to be a Gib- 

 berella. Literature is rich with such errors. 



Sections of a fossil wood from asphalt lake near Los Angeles, Cal. 

 Dr. Albert Mann. Thin sections of the petrified wood were exhibited 

 under a microscope which showed fungus hyphae. Brief notes were 

 given as to the apparent method of the groA\'th of the fungus and the 

 possible identification of the tree was discussed.

THE BIOLOGICAL SOCIETY OF WASHINGTON 



The 414th regular meeting was held at the Cosmos Club on October 

 18, 1913, with former President L. 0. Howardin the chair and 61 persons 

 present. 



The program consisted of, three communications: 



The Federal migratory bird regulations and their assistance in the con- 

 servation of bird, life in America: T. S. Palmer. The speaker outlined 

 briefly the history of the Weeks-McLean Bill, approved INIarch 4, 1913, 

 and of the adoption of regulations for its enforcement which have been 

 promulgated by the Department of Agriculture under proclamation of 

 the President dated October 1, 1913. Maps of the winter and breed- 

 ing ranges of some of the species of birds affected were shown, together 

 with another showing the division of the country into two zones. Rea- 

 sons were given for the exceptions in certain States to the general closed 

 season. In general the beneficial effects upon the bird life of the coun- 

 try expected as a result of the enforcement of the • Federal law were 

 pointed out. Hugh Smith and Col. Joseph JI. Acklen took part in 

 the discussion which followed. 



The breeding of the loggerhead turtle: W. P. Hay. The communica- 

 tion was accompanied by lantern slides. It was an account of observa- 

 tions of • the habits and reproduction of the diamond-backed terrapin 

 and the loggerhead turtle made at Beaufort, North Carolina. This 

 place is near the northern limit of the distribution of the loggerhead 

 turtle and the speaker was of the opinion that normally in this latitude 

 few of the eggs of the species are left to hatch and that the young 

 from those that may hatch all perish with the first cold weather.
