2.3.3 The Consing Dot

If a token consists solely of dots (with no escape characters), then an error of type reader-error is signaled, except in one circumstance: if the token is a single dot and appears in a situation where dotted pair notation permits a dot, then it is accepted as part of such syntax and no error is signaled. See Section 2.4.1 (Left-Parenthesis).
