i think he's a delta or super delta, although his dorsal and anal are typical of a veiltail, which you'd expect from a roundtail. their tails are shorter though, almost a perfect circular shape.

How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger-all down here on Earth.
