The slightly heterocercal character of the tail is well defined. The connective- tissue bones, usually injured in prepared skeletons, are shown in their normal relations. The radiograph of the skate (Raia crinacea) displays the car- tilaginous skeleton to good advantage for examination. The attachment of the exterior spines to the pectoral rays and the shoulder and pelvic girdles, with the claspers attached to the lat- ter, are easily observed. The radiograph of the sea-horse (Hippocaiiipiis liiidsoiiiiis) is a good presentation of the exoskeleton of fishes of its type, al- though made from a dried specimen. Had a fresh specimen been used the definition would have been sharper. This is the largest example of this species ever brought to the Ac^uarium, and it is shown natural size. In the Nautilus the radiograph shows the septa which divide the air chambers and the connecting siphuncle. As an aid to conchologists it would often be valuable, as, for instance, in re- vealing the plates on the pillar in many of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original New York Zoological Society.
