The first part of this paper presents near infrared spectra (1650-10350 A) of galactic and mainly Magellanic Wolf Rayet Stars. The spectra are compared to the ones published previously in the 'Catalogue of near infrared spectra of southern galactic WR stars' and some peculiarities are pointed out. In the second part, the hydrogen signature in the Paschen series is discussed. For all the galactic and Magellanic objects in which such a signature could be quantified, a value of the H(+)/He(++) ratio has been derived and compared to previous estimations based on the Balmer series.
