 * Chiang lung
 * Li lung

 * Shen lung
 * T'ien lung
 * Tun mi lung
 * Yu lung

Abilities
Unlike most other dragons, most lungs did not have breath weapons. Instead, they had other powerful magical abilities, which varied among their kinds. All lung dragons could detect the thoughts of other creatures. They could turn invisible at will and polymorph into the shape of just about any small to large creature that they wanted. Lung dragons could also shift to other planes of existence.

Personality
Unlike chromatic and metallic dragons, lung dragons had a wide range of moral and ethical alignments.

Society
Most lung dragons were members of the Celestial Bureaucracy, serving with specific tasks, depending on the species of lung.

At the very least, lung dragons spoke the Spirit Tongue in addition to the Draconic language.

Ecology
Most lung dragons could survive from consuming minerals alone, although some varieties did enjoy the taste of meat on occasion.
