 See the snake on the site: San Luis Obispo "Pacific form":

 

 As aforementioned, there are 2 to 3 rows of spots on the side of the Pacific Gopher Snake. However, the San Diego Gopher Snake (P. c. annectens) has 3 to 4 rows of smaller spots on their sides. The Pacific Gopher Snake's saddle spots do not have the barren characteristic as the San Diego Gopher Snakes do. Also, the second row of spots are much larger on P.c. catenifer compared to P.c. annectens. Finally, the Pacific Gopher Snake generally has more saddle spots than the San Diego Gopher Snake.[3]

 

 

 Below are 3 catenifer of two subspecies. The upper is catenifer annectens from San Luis Obispo County, the middle snake is catenifer catenifer from Kings County, and the lower snake is catenifer annectens from Ventura County. Images are from a slide by Patrick Briggs scanned to the computer and to this site.
