  In [J. T. Matta et al., Phys. Rev. Lett. 114, 082501 (2015)] a transverse
wobbling band was reported in $^{135}$Pr. The critical experimental proof for
this assignment is the E2 dominated linking transitions between the wobbling
and normal bands, which are supported by two experiments performed with
Gammasphere and INGA. However, the M1 dominated character cannot be excluded
based on the reported experimental information, indicating that the wobbling
assignment is still questionable.
