Ethnologue's online language database has been really helpful over the years. Thank you very much for this service. I might be misreading your website or Rymer (2014: 340), but it looks like an alternative name for the Mexican language Seri might be "Cmiique Iitom." I am not sure that Ethnologue is listing that name as an alternative right now, so I thought that I would mention it in case you want to add it. Rymer, Russ. "Vanishing Voices."

We will add this name as an alternate name for Seri [sei] in the 19th edition database.
