It is found that matter collineations turn out similar to Ricci collineations with different constranit equations. We solve the constraint equation for a particular case and obtain three cosmological models which represent perfect fluid dust solutions.20 pages, no figure, LatexGeneral Relativity and Quantum Cosmologytext
