This is the definition of "lithyalin" from David Whitehouse's Glass Glossary
Lithyalin (from Greek lithos, “stone”)
A type of glass, developed in Bohemia by Friedrich Egermann (1777–1864), that is opaque and has a marbled surface resembling semiprecious stones.
Does that help you? I believe "Chameleon glass" is an American collector's term, not used widely in publications.
I have attached a bibliography of books and articles that refer to Friedrich Egermann and lithyalins. Another deals with hyalith.
Walter Spiegl's text may be a good reference for you: Facts and fiction in the history and manufacture of lithyalin. [S.l. : s.n., 1981]  p. Typescript of a lecture given by the author at the Corning Museum of Glass, 21st Seminar, October 30, 1981.

I am sending this article to you -- it's a great overview: Brozová, Jarmila. “Bohemian Lithyalins and Friedrich Egermann” Journal of Glass Studies v. 23, 1981, pp. 64-73, ill.
I do not know of a single source that describes all glasses produced by Egermann and Count Buquoy (different colors of lithayalin and different colors of hyalith--including agatine).
