Yeah, it was never given an official name...

Kirito simply compared it to a Lungfish

Sword Art Online, Volume 1, Chapter 19 : "Ooh, it's running on the ground... So it's a dipnoan...?" With a link to Dipnoans (lungfish) That's as far as any "confirmation"... So basically the category was wrongfully removed...
