Liguus fasciatus matecumbensis
Pilsbry, 1912
Collected on Upper Matecumbe Key, FL.
This is a shell from the colony on Upper Matecumbe Key.
The matecumbensis together with form subcrenatus
are devoid of any pink pigmentation. Pilsbry considered
these two shells to be difficult to place in his classification
scheme because of a lack of definite characters referenced
to other color patterns within the South Florida populations.
L= 50.2 mm ,  W= 26.7 mm

Liguus fasciatus matecumbensis
form subcrenatus

Lower Matecumbe Key, and sympatric in other Liguus
colonies of the Key except with dohertyi.
It is believed to be extinct in its native location,but survives
in transplanted colonies in the Everglades National Park.
