Cryptozoology has a bad name due to its association with such oddities as Bigfoot and the Lochness Monster. However, some crypto-zoology does involve looking for known species in places they are not known to inhabit.
When I went looking for Muhlenberg's Bog Turtle in Vermont this is an excersize in cryptozoology. This species does exist and is rare but as of yet has not been found in Vermont. It does appear in Maine and in places in NY State. My odds of finding one are not good as it is nocturanal. This combined with its habitat could be the reason it has not been found thus far.
Remember most Vermonters have seen a Moose once or twice in their lives and have never seen a Black Bear and both live in the State. It may not be so far fetched that a six inch nocturnal reptile may be present in the state, especially given that it inhabits bogs.
