I believe it is a layout Genga. 

The following info on layout genga came from Brian Anime 
info page. If you have further question on genga or other
parts of the anime process, I would follow the link on the 
main cel.org page to his anime info page or to Ash's or
Yann's cel info pages. All three are quite useful and between
the three, they seem to have answered just about every
question I have thought involving the animation process.

Layouts

Layouts are usually easier to spot than other types of
genga. One of their trademarks is that they are almost
exclusively done on studio paper (with the studio name
on it), but I have seen some done on colored paper so
don't take that as a rule of thumb! The big thing to look
for in a layout is the presence of the background. As
you'll notice in this one the background is drawn in as
part of the sketch. This is a rather time consuming task,
and these sketches are done early in the production time
line. Layouts are the least plentiful of the different genga
types (if you don't count storyboards).
