In this paper, we study the conchodial surfaces in 3-dimensional Euclidean space with
the condition ∆xi = λixi where ∆ denotes the Laplace operator with respect to the first
fundamental form. We obtain the classification theorem for these surfaces satisfying under
this condition. Furthermore, we have give some special cases for the classification theorem
by given the radius function r(u, v) with respect to the parameter u and v.
