More wildlife at work

It appears the cold weather is driving the critters indoors at work.  Yesterday I was sitting at my computer when I noticed a spider crawling on my lap.  The leg span of the thing was about 2".  I looked down, saw it, then jumped up to brush it off me!

Today I was closing up the lab for the weekend when I saw something on the floor move.  It was a baby snake, which I scared into this resting spot:

I didn't see any rattles, but I still didn't want to get bitten, so I got the broom and swept it outside.  Here it is on the way down the hallway:

And here it is coiled up on the mat by the door before I swept it outside:

From what I can find online, this looks like a gopher snake or a bullsnake.
