Background information 

Before the logo and name "Aamaarazan" first appeared on a display graphic in "...But to Connect", this species was originally identified as the "Aammazaran", a name revealed by Teresa E. Victor, who portrayed one of the first two aliens to appear in The Voyage Home. Victor remembered, "Everyone [who worked on Star Trek IV] just called us 'the little bees because we looked like bees and Aammazaran was too hard to remember." (Star Trek: The Official Fan Club Magazine issue 56, p. 20) 

Wearing the costume and make-up required to play an Aammazaran was considerably difficult. "First I had a bald cap which went over my hair," reflected Victor. "They used gel to flatten my hair down. It took about 45 minutes to get ready. They had to paint the parts of my arms that were exposed yellow. That wasn't easy to get off either! We had a hard time breathing through the masks we wore. They just let us hang them down our necks in between takes. When we had to walk, we could barely see where we were going. We had to hold onto each other and have one person lead. We always couldn't wait till the assistant director would yell, 'Heads off!' We would say, 'Oh, thank God! We can breathe!" (Star Trek: The Official Fan Club Magazine issue 56, p. 20)

According to the reference book Star Trek IV Sourcebook Update, the pair of Aammazaran councilors were referred to as Zaranites, a species that appears in . Also according to that book, the pair of Star Trek IV aliens were depicted using reused Zaranite breathing masks from the earlier film.
