In a recent paper Saile and Koch present a detailed experimental reinvestigation of the excitonic spectrum of solid neon. With respect to a previous work, relevant corrections are introduced in the case of the $n=1\mathrm{}$ excitonic transitions. Saile and Koch compare their results with theoretical studies which were, however, based on the previous data. Other relevant theoretical works have been published meanwhile. We provide a series of comments to the new experimental data, on the basis of the complete series of the previous theoretical works.
