Shapes and sizes of ommatidia in six genera of stomatopods from different luminous habitats are described. Cornea-cone apertures and acceptance angles have been calculated. The ommatidia belong to the apposition type with fused rhabdoms as in most Ma

1. 1. The distribution of pseudopupils in the eyes of representatives of five genera of Stomatopoda has been studied. 2. 2. A triple pseudopupil is seen when the eye is viewed perpendicularly to the specialized middle band on the cornea, but a double

The cornea in most stomatopods is divided into two halves by a band of specialized ommatidia, the middle band. This band is absent in the Bathysquilloidea, but present in the three other superfamilies. It is two facets wide in the Squilloidea and six

Leptinotarsin, a toxin found in the hemolymph of the beetle Leptinotarsa haldemani , can stimulate release of acetylcholine from synaptic termini. Leptinotarsin causes an increase in the frequency of miniature end plate potentials (mepps) of the rat

• Numerous studies of cardiac muscle mechanics have produced contradictory conclusions. The present paper discusses a few salient points about cardiac muscle mechanics, but it is not a critical review of the literature such as that recently publish

1. 1. Stomatopods have double eyes. 2. 2. In the middle band dividing the two halves of the eye ommatidia are perpendicular to the cornea. 3. 3. Rows of ommatidia parallel to the middle band have divergent optical axes. 4. 4. In the columns across th

1. 1. Studies have been made on the contractile properties of the proboscis retractor muscle of the marine worm, Golfingia gouldii . 2. 2. This muscle is non-striated and its fiber dimensions are in the order of 5 μ by 1000 μ. 3. 3. At short length

The compound eye of the lobster H. vulgaris has a single lobe; its ommatidia are uniform except in length. Each ommatidium consists of a corneal facet, two corneagenous cells, four cone cells, a four-part crystalline cone, an elongate cone stalk, sev

The toxin of a hoplonemertine, Paranemertes peregrina Coe, was purified by solvent fractionation, aluminum oxide chromatography, and crystallization of the picrate. Spectral measurements indicated that the toxin is anabaseine, 2-(3-pyridyl)-3,4,5,6-t
