Brown; Large forward pointing chelicerae; cigar shaped abdomen. So I think it is Clubionidae.

Good reasoning!! However, Eutichuridae (family - Slender sac spider) also have quite similar characteristics (including the ones you have mentioned) so it's worth checking over them as well; they're both sac spider families (one is "slender" and one is "stout"). From the images and descriptions I've seen, generally, if the chelicerae seem to resemble tetragnatha sp (forward-pointing, long, point away from each other), then it's more likely to be Cheiracanthium sp. Also, I have noticed that the third pair of legs on Cheiracanthium sp are distinctly shorter than the others - especially in comparison to the first two pairs of legs. These features aren't always clearly different, but with this one, I'm quite sure that it's a male Cheiracanthium sp. Whyte & Anderson p.143-147 has good reference photos of Cheiracanthium sp.
