DURAND author in neurosecretory fiber endings in the sinus glands, it is possible that practi- cally all of the material in a given axon ending is released after molt. In the cray- fish this release takes place in a period of not more than a few hours (Pyle, 1943). The accumulation of stainable material in the Type 2 neurosecretory cells of the x-organ prior to molt has been explained on the basis of a hypothetical witholding of molt-inhibiting hormone by the sinus gland and a continued synthesis of hormone or it
