DISCUSSION AND CORRESPONDENCE 



DISCOVERY OF SAUROPOD DINOSAUR RE- 

 MAINS IN THE UPPER CRETACEOUS OF 

 NEW MEXICO 



In a small collection of vertebrate fossils 

 recently received at the U. S. National Mu- 

 seum, from Mr. John B. Eeeside, Jr., geolo- 

 gist of the U. S. Geological Survey, was an 

 almost complete left scapula of a large 

 Sauropodous dinosaur. The importance of 

 this particular specimen lies in the fact that 

 it was collected by Mr. Eeeside in the Ojo 

 Alamo formation. Upper Cretaceous, as de- 

 veloped in the San Juan Basin in northern 

 New Mexico. Since the remains of Sauropod- 

 ous dinosaurs have not been known before 

 above the early Lower Cretaceous in North 

 America, the extension of their geological 

 range into the Upper Cretaceous, as indicated 

 by the present discovery, is of the greatest 

 interest. 



The close general resemblance of this 

 bone to the described scapulae of the Sauropoda 

 from Morrison formation, its great size (five 

 feet in length), and the fairly good state of 

 preservation, precludes the possibility of mis- 

 taken identification, and the determination of 



its geological occurrence by a geologist of the 

 acknowledged ability of Mr. Eeeside, who has 

 an intimate acquaintance with the geological 

 structures and succession of formations in the 

 San Juan Basin, due to two field seasons 

 spent in the area, places the determination 

 of the geological position of the specimen be- 

 yond all question of doubt. 



This preliminary announcement will be fol- 

 lowed by a more detailed account of the speci- 

 men when its preparation now in progress is 

 completed.

LEAF STRIPE DISEASE OF SUGAR CANE IN 

 THE PHILIPPINES 



In early 1920, a firm of Japanese sugar- 

 cane growers introduced cane points of 

 Formosan cane varieties for use on their 

 plantation in Eizal Province, Luzon. The 

 sugar-cane points, according to the Japanese 

 firm, had been grown by the Experiment 

 Station of the Japanese Government in 

 Formosa. On arrival at the port of Manila, 

 the shipment was intercepted by the Philip- 

 pine plant quarantine inspectors, but the 

 Japanese growers prevailed upon the too- 

 lenient government official to allow them to 

 bring in the cane, after dipping it in Bordeaux 

 mixture. 



Upon the appointment of the writers to the 

 plant disease laboratories in March, 1920, 

 they became cog-nizant of these circumstances, 

 and since then, periodical inspections of the 

 planting have been made. In April, 1921, 

 the cane having been ratooned numerous 

 cases of etiolation of the young plants were 

 observed. Such light-colored plants were 

 very conspicuous and could be observed at a 

 considerable distance from the field. 



On the lower surface of affected leaves, a 

 white spore mass was abundant; the patholo- 

 gical condition was of course immediately 

 suggestive of downy mildew of the sugar cane. 

 Examination of the fungus evidenced the 

 presence of a Sclerospora species. This 

 pathological condition could not be found on
