## Abstract Mandibular glands from destalked male spider crabs were fixed in glutaraldehyde‐paraformaldehyde, post‐fixed in 1% osmium in phosphate buffer, dehydrated in acetone and embedded in Spurr's low‐viscosity medium ('69). The glands hypertrophy and several changes occur in the subcellular cy

Abstract
The cells of mandibular organs of female Libinia emarginata exhibit changes in substructure during molting and vitellogenesis. The cytoplasm is that of a steroid‐hormone producing cell. The cells do not appear to produce ecdysones.

Using two-step reverse phase HPLC, we isolated and purified three peptides with mandibular organ inhibiting hormone (MO-IH) activity from the spider crab Libinia emarginata. One of the peptides, P22, gave a yield of 355 ng/SG. The others gave lower yields: P21, 9 ng/SG; P25, 67.5 ng/SG. The molecul
## Abstract The ecdysial glands of mature male __Libinia emarginata__ are pale, yellowish organs composed of lobes of epithelial cells having oval nuclei which are often eccentric and which have one or two nucleoli containing amorphous granular material and coarse strands. The plasma membrane borde
