Hi all,

Using ipython

 info special

 yields

  Bessel Functions

    jn       -- Bessel function of integer order and real argument.
    jv       -- Bessel function of real-valued order and complex argument.
    jve      -- Exponentially scaled Bessel function.
    yn       -- Bessel function of second kind (integer order).
    yv       -- Bessel function of the second kind (real-valued order).
    yve      -- Exponentially scaled Bessel function of the second kind.
    kn       -- Modified Bessel function of the third kind (integer order).
    kv       -- Modified Bessel function of the third kind (real order).
    kve      -- Exponentially scaled modified Bessel function of the
                  third kind.
    iv       -- Modified Bessel function.
    ive      -- Exponentially scaled modified Bessel function.
    hankel1  -- Hankel function of the first kind.
    hankel1e -- Exponentially scaled Hankel function of the first kind.
    hankel2  -- Hankel function of the second kind.
    hankel2e -- Exponentially scaled Hankel function of the second kind.

    lmbda       -- **Sequence of lambda functions with arbitrary order v.


kn denotes the modified Bessel function of the third kind.

However the term "Modified Bessel function of the *second* kind" seems
to be more common.

It would be nice if "*second*" could be added.
