No 3DS games sold enough in the US to place in the top ten last month, according to NPD data. But 3DS sales were happening just under the surface, with many 3DS games making it into the (undisclosed) top 25 games of February.

The NPD told Joystiq that "some examples" of the 3DS titles that made the list include Skylanders: Spyro's Adventure, Mario Kart 7, Super Mario 3D Land, FIFA Soccer, Lego Star Wars 3: The Clone Wars, Lego Pirates of the Caribbean, Resident Evil: Revelations, and Mario & Sonic at the London 2012 Olympic Games -- the last two on that list being February releases.

That's ... a significant portion of the top 25. It's also evidence of a reasonably engaged 3DS install base, and therefore stiff competition for the PS Vita, which came out in February. The Vita's Uncharted: Golden Abyss placed somewhere in the top 20 (at least in retail; Vita games also have digital sales not charted by NPD).
