ABSTRACT 1. The specific alpha2 adrenoceptor agonist B-HT 933 significantly reduced the rate of melanin dispersion in crabs transferred from a white to a black background. 2. The specific alpha2 adrenoceptor blockers rauwolscine and yohimbine significantly increased the rate of melanin dispersion in crabs transferred from a white to a black background. 3. Rauwolscine and yohimbine, but not the alpha, adrenoceptor blocker indoramin, antagonized B-HT 933. 4. In crabs pretreated with the catecholaminergic neurotoxin 6-hydroxydopamine, which inhibits melanin dispersion, B-HT 933 did not produce further significant inhibition in the rate of melanin dispersion. 5. None of the drugs has been found to affect melanin migration in melanophores of isolated legs. 6. The results are consistent with the hypothesis that presynaptic adrenoceptors very similar to alpha2 adrenoceptors of mammals regulate impulse-mediated norepinephrinergic neurotransmission in the fiddler crab Uca pugilator, norepinephrine triggering release of a melanin-dispersing hormone.
