4.29.11

nalinī nālinī nāse gandhaḥ saurabha ucyate /
ghrāṇo 'vadhūto mukhyāsyaṃ vipaṇo vāg rasavid rasaḥ //

11. Nalini and Naalini are the nostrils, and smell is called Sourabha; the ever open sense of smell is called Avadhuta (the free Vayu) (associated with that organ) and *mukhya* is the mouth; and Vipana is the organ of speech and taste (the sense of taste at the tip of the tongue) capable of determining tastes.
