dc.description.abstract	We have presented a series of P Cygni type profiles of special lines computed by employing different velocity laws of expansion in a spherically atmosphere. A comparison has been made with those of Beals classification. In many cases we have calculated the profiles by changing the density and velocity according to the equation of conservation of mass viz., 4 pie r/sup2/ rho v = constant where rho and v are the density and velocity at the radial point r respectively. We have employed the line transfer equation in comoving frame in certain test cases, to obatin the source function which is being used to calculate the profiles observed at infinity. However, this procedure is relaxed in many cases as it becomes time consuming and we have employed a source function which is a function of either the radius or the number of a given shell from the centre of the star	en
