Abstract : A study was made of the nervous system in Dermacentor pictus. Ticks were fixed in Bouin's fluid and stained with paraldehydefuchsin by Gabe's method and with paraldehyde-thionine by Paget's method, modified by Panov. Only unfed ticks were utilized in this work. When applying these staining methods, the neurosecretory cells are clearly distinguished within the neuron mass of the brain in D. pictus by the larger size of their cell bodies and presence within them of a staining secretion. The average size of the neurosecretory cell bodies is 10 to 12 microns. Most nuclei of the neurosecretory cells do not vary in size from ordinary neurons (5 to 6 microns). In D. pictus, neurosecretory cells are found in all ganglia of central nervous system.
