\textit{J. W. Anderson} and \textit{R. D. Canary} [Invent Math. 126, 205-214 (1996; Zbl 0874.57012)] have constructed a series of examples of 3-manifolds \(M\) for which the space \(CC(\pi_1(M))\) of convex co-compact representations of \(\pi_1(M)\) in \(PSL_2(C)\) is disconnected, but has connected closure (in the topology of algebraic convergence). For these examples the intersection of the closures of any two path components of \(CC(\pi_1(M))\) is non-empty. In the present paper the author proves that for these examples there is a connected, uncountable set of geometrically finite representations which is contained in the closure of every path component of \(CC(\pi_1(M))\). The construction shows that in some sense this set can be chosen to be ``large'', in that given any \(K \geq 1\) the set contains all of the \(K\)-quasiconformal deformations of some geometrically finite representation of \(\pi_1(M)\) (this representation depending on \(K\)).
