Jalrow

Jalrow is a Tok'ra who heard that Jack O'Neill had disappeared on the planet P5X-777. It promptly flew over the planet, scanning for life signs, and found none. Jalrow then notified Stargate Command and SG-1 of its results and apologized. Later, it may have flown the tel'tak that picked up O'Neill and Harry Maybourne from the planet's moon.

Behind the scenes
Jalrow is never seen; only its voice is heard in its transmission.
