Mosquito species inhabiting a high mountain area (9000 to 12,000 feet) in south-central Colorado west of the Continental Divide comprised 11 Aedes, 4 Culiseta, 1 Culex, and 3 chaoborines. They can be placed by altitudinal associations in two major groups: 1) mountain species, subdivided into alpine

The golden-mantled ground squirrel (Citellus lateralis lateralis) and the least chipmunk (Eutamias minimus consobrinus) were studied in the mountains of west central Colorado where the two species are sympatric and display marked similarities in habitat selection, life cycles and general behavior pa

The dispersal was associated with changes in home ranges and with the avoidance of dominant animals by subordinate animals, and females moved from being concentrated in the centre of the colony to being more widely dispersed during the vernal period.

Two new endocommensal fungi belonging to the Genistellaceae (Harpellales) were isolated in pure culture from the hindguts of Diptera larvae: Smittium culesitae from the mosquito Culesita impatiens, on a 10% brain‐heart infusion, and S. simulii from the black fly Simulium argus, on a potato dextrose‐

Peromyscus gossypinus and Peromyscus nuttalli were collected near Ruston, Louisiana from 1 September 1960 to 1 June 1961. Peromyscus maniculatus was collected near Gothic, Colorado from 1 August 1961 to 20 August 1961 and in the Black Canyon of the Gunnison National Monument from 23 August 1961 to 1
