group. Reginald Innes Pocock revised the classification of this genus in 1916 as comprising the tiger (P. tigris), lion (P. leo), jaguar (P. onca), and leopard (P. pardus) on the basis of common cranial features. Results of genetic analysis indicate that the snow leopard (formerly Uncia uncia) also belongs to the genus Panthera (P. uncia), a classification that was accepted by IUCN Red List assessors in 2008. The tiger, lion, leopard, and jaguar are the only cat species with the anatomical structure that enables them to roar. The snow leopard is the only one that cannot roar in this genus. The primary reason for this was formerly assumed to be the incomplete ossification of the hyoid bone. However, new studies show the ability to roar is due to other morphological features, especially of the larynx." - (en.wikipedia.org 23.05.2021)
