O. Beebe, 439 W. 54th street, Los Angeles, April 25. Chairman J. 

 Z. Gilbert, presiding. 



Mr. J. O. Beebe gave a very interesting and instructive talk on 

 Crinoids, of which he has the most important collection outside of the 

 Museum of Comparative Zoology at Harvard, and the Smithsonian. 

 Mr. Beebe collected a great many of those in the last named institu- 

 tions. By means of models he showed the evolution of the Crinoids 

 from the simplest forms up to the present starfish. Wachsmuth and 

 Springer are the leading authorities on these nearly extinct animals, 

 and he showed their large and expensive work. There were many 

 questions and answers in a very informal way which added to the 

 pleasure of the talk. 



Mr. B. Burton, a mining engineer, gave an account of the finding 

 and excavation of prehistoric animals in Utah, Wyoming and other 

 Rocky Mountain states. 



The following men were present: F. C. Clark, J. O. Beebe, H. B. 

 Dixon, J. Z. Gilbert, Wm. H. Knight, H. H. Newcomb, R. L. Beards- 

 ley. B. Burton, John Clark and F. Grinnell, Jr. 



The meeting adjourned at 10:30. 



F. GRINNELL, JR., 



Acting Secretary. 



On Thursday evening, June 12, a natural history club for boys was 

 organized at the home of Rutherford Moore, 2242 Hobart Boulevard, 

 Los Angeles. The following boys were present: Aten Lytle, George 

 Miller, Walter Cline, Frank P. Alexander, Donuil Hillis, Rutherford 

 Moore, Aubrey Eastham, Jack Phillips, Clifford Grant, James F. 

 Moore. Charles Parker, James Cuzner. Ralph Church, Harold Grieve 

 and F. Grinnell, Jr., from whom a president, vice-president, secretary 

 and treasurer were chosen. The name Lorquin Natural History Club 

 was chosen, in memory of the first collector of Californian insects and, 

 plants in 1849. It was decided to hold meetings on the first Fridays 

 of each month, and frequent field excursions. The first field trip was 

 on Saturday, the 14th of June, to the Ballona Creek region west of 

 the city, where a lot of specimens were collected. In a few years this 

 club, and others, will provide some real active members for our 

 Academy. 



Mr. Fordyce Grinnell, Jr. 



Dear Sir: Your article on Eugonia Californica in the last Southern 

 California Academy Bulletin leads me to write concerning the wide 

 devastation of Ceanothus Cordifolius by this insect in the southern 

 Sierra Nevada in 1911. In August of that year I was traveling through 

 the Kaweah and Tule river regions on a botanical expedition. Tlie 

 defoliation was most marked and of widest extent (occuring for several 

 miles) on the South Fork Kaweah at 6500 to 7500 feet altitude. Large 

 areas of the shrubs did not display a single leaf. The denudation was 

 almost entirely confined to open sunny slopes. Colonies in shade of 

 forest or on north slopes so sharp as to be largely protected from the 

 sun, were not affected. The forest was mainly mixed Abies concolor- 

 and magnifica. 



Yours very truly, 



WILLIS L. JEPSON.
