Hey Gord,
I've never heard of either of those either. Can you give us an idea of size and body color, as well as shape (head vs body proportions). For example, sleeper gobies have a fairly large head in comparison to their bodies. I have noticed that the larger headed ones seem to be sand sifters. Other gobies are more streamlined like a neon goby or redheaded goby (I'm just speaking on the ones I have).
You could also try gobyfrontiers
http://uri.sakura.ne.jp/~dd/goby.htm They have an awesome site with tons of pictures. If you don't find it there try picking one that has the general body shape.
Hope this helps. Let me know if you do find it
