| The rhombic dodecahedron and the common trapezohedron are the most common forms. |
| The pectoral fin is set low on the lateral flank behind the notch of the cleithrum and is supported by a small rounded lobe covered with minute rhombic scales. |
| Autunite, a hydrous phosphate of uranium and calcium, crystallizing in the rhombic system in yellow plates. |
| A few sharp rhombic crystals of rhodochrosite without siderite coating were also found in the Eagle mine. |
| The tail round, tapering, with imbricate rhombic seales, with the keels forming longitudinal ridges. |
| It crystallizes from water in large rhombic crystals, which melt at 118 C. Oxidizing agents convert it into benzaldehyde. |
