Answer
An comprehensive online database of the chromosome numbers of all living species most likely doesn't exist. This Wikipedia article is the best and most complete reference comprising animals that I can personally find on the internet.
This source in Spanish, which I've translated with Google Translate reads:
Canedo Delgado (1999) performed the karyotype description of the three species of the genus Pygoscelis , noting that there is a high homology both numerically and morphologically: Pygoscelis antarctica presented 2n = 92, Pygoscelis papua 2n = 94 and Pygoscelis adeliae 2n = 95 in females and 2n = 96 in males.
Also, note that chromosome number cannot be "guessed" or "assumed" for closely-related species. As shown above, the three Pygoscelis species have a high homology, but have very different chromosome numbers.
The other chromosome number you found for the species (38) is actually that of the Emperor penguin, as a simple Google search shows.
