I found this little guy yesterday. Not as familiar with salamanders as I am with snakes. Looking it up on the web produced…. http://www.californiaherps.com/salamanders/pages/b.nigriventris.html an excellent web page that shows many of the difference between very similar species. I forgot to take a picture of its belly. That is how you distinguish between Batrachoseps major major, Garden Slender Salamander and B. nigriventris according to the website. Maybe I can find the little guy again.
