My local natural history museum has given up on subspecies level identification of their stock.
The reason - when I talked to them, they said almost every herp they get is donated or rescued.
Many are mis-identified when they get them.
Species level is all they concern themselves with as subspecies can be difficult in some cases to determine without locality data.
Both their gopher snakes are clearly pac gophers - and are just identified as Pine/Bull/Gopher snake - Pituophis melanoleucus
They have about 4 or 5 california kingsnakes (kept together, btw - well fed adults) labeled simply as Common Kingsnake - L getula
Their Southern Alligator Lizard collection looks to contain both California and San Diego subspecies.
I have no idea what subspecies their zonata is, it is always hidden.
They just don't care about subspecies level of identification.
I suspect many small museums don't care about precise identification unless they have a biologist on staff who is a herp nut him or herself.
They don't even have their western pond turtles identified to the subspecies level, and they regularly breed them - supplying other museums with hatchlings. I think they are all northwestern, but I'm not positive.
