A005002 inconsistent with wikipedia entry about Stirling numbers of the second kind?

[Jonathan Post]

Does anyone have, in hardcopy, the  J. Riordan 1979 reference cited?
There seems to be an inconsistency between a wikipedia entry about
Stirling numbers of the second kind, allegedly to count rhyme schemes,
and A005002. Embarassing to me, as a much-published poet to be
confused here.

Both differ from:

%I A005002
%S A005002 1, 4, 13, 41, 134, 471, 1819, 7778
%N A005002 Number of rhyme schemes.
%C A005002 wikipedia: "The Stirling numbers of the second kind can
represent the total number of rhyme schemes for a poem of n lines.
S(n,k) gives the number of possible rhyming schemes for n lines using
k unique rhyming syllables."

%e A005002 a(3) = 4 because for a poem of 3 lines, there is 1 rhyme
scheme using just 1 rhyme (aaa), 3 rhyme schemes using two rhymes
(aab, aba, abb), and one rhyme scheme using 3 rhymes (abc); we exclude
the last as only technically a rhyme scheme but with no rhymes, and
have 1 + 3 = 4.
a(4) = 13 because for a poem of 4 lines, there is 1 rhyme scheme using
just 1 rhyme (aaaa); 7 rhyme schemes using two rhymes (aaab, aaba,
abaa, baaa, aabb, abab, abba), noting that abbb is equivalent to baaa,
and that bbaa is equivalent to aabb; 6 schemes using 3 rhymes (aabc,
abac, abca, abbc, abcb, abcc); 1 using no rhymes (abcd) which we
exclude, giving 1 + 7 + 6 = 14, but -- whoops -- that's not 13 as
desired.

These in turn suggest that the wikiedpia entry comes from:

The former may refer to:
the number of rhyme schemes, or logical relatives (C. S. Pierce, Amer.
J. Math. vol. 3 (1880) p. 48) with m plexes of nuance
