Shore collecting stations of the Eastern Pacific Expeditions of the New York Zoological Society.their diet.0. occidentalis is a predator and scavenger.3. 0. gaudichaudii is diurnal, occidentalis nocturnal except when very young.4. In contrast to the racing dodging, burrowing adults, the young of gaudichaudii run only a short distance when pursued, then flatten themselves in the sand, where protective coloration aids them in escaping observation.5. Also included in the present paper are descriptions of color in life, stridulation, habitat, burrows and daily schedule, with special emphasis on gaudichaudii.Abdominal appendages of the three American species, gaudichaudii, occidentalis and albicans, are illustrated.
