Order Proboscidea, gen. et sp. indet. 
Material. — ChM.PV2300, ChM.PV2307, four tusk fragments; 
ChM.PV2303, skull fragment; ChM.PV2306, scapular fragment; 
ChM.PV2733, vertebral fragment; HS.A-117, HS.A-121, HS.A-27, ver- 
tebral fragments; HS.E-26A, HS.A-86, fragmentary metapodials; HS.E- 
67, phalanx. 
Order Sirenia 
Family Trichechidae 
Trichechus (Linnaeus) sp. indet. — manatee 
Material. -ChM.GPV627, rib fragment; ChM.PV2315, ChM.PV2317, 
ChM.PV2453, ChM.PV2321, four rib fragments; ChM.PV2748, thoracic 
vertebral fragment; HS.E-75, rib fragment; HS.A-33, right mandible. 
Remarks. — Trichechus is totally aquatic and prefers sheltered bays or 
sluggish rivers. They are known to wander far inland in Florida rivers. 
Simpson (1932) indicated that Pleistocene sirenians commonly occur in 
inland fresh water deposits of Florida. Pleistocene Trichechus remains are 
known along t the Atlantic coast from Maryland to Florida (Simpson 
1932).
