Isolation of Histoplasma capsulatum from a Texas cave.

Sixty-three soil samples collected from caves in Texas and the Republic of Mexico were studied to determine the incidence of pathogenic fungi by the use of the flotation technique in mice.Histoplasma capsulatum was isolated from the Kickapoo cave in Texas, and there was some histopathological evidence of its presence in the soil of Devil' cave (Cueva del Diablo) in Mexico. In the latter case, an incidence of human contact with the cave which resulted in an illness is presented.

Notes on a Small Collection of Amphibians and Reptiles from the Vicinity of the Pinacate Lava Cap in Northwestern Sonora, Mexico

During a 13-day period in mid-June and an 11-day period in late July and early August, we had an opportunity to collect amphibians and reptiles in the vicinity of Sonoyta, Sonora. The June visit to the area was made by Smith, his wife, and daughter; the July-August visit, by Hensley and Smith. Upon arrival in Sonoyta the first time, it was our good fortune to discover that a new black-top highway had just been completed between Sonoyta and San Luis, some 128 miles to the west by northwest. The eastern portion of the new road is the old Camino del Diablo which formerly entered Arizona a few miles west of Sonoyta. The new highway parallels the International Border on the Mexican side all the way to the Colorado River, thus making accessible by road the northwestern corner of the state of Sonora.
