Edisto Island Fossil Vertebrates

collection of Mrs. Eddie Gue, RP 3 and one molar fragment. 
Remarks.— The limited available Mylohyus material prevents definite 
specific determination. Lundelius (1960) recognized Mylohyus nasutus 
and M. fossilis, based on differences in size and geographic distribution. 
Mylohyus fossilis is characterized as a smaller species from eastern North 
America, while M. nasutus is a larger species generally occurring west of 
the Appalachian Mountains. Ray (1967) did not support Lundelius’ con- 
clusions but suggested instead that the variation in size between supposed 
species of Mylohyus is the result of sexual variation within one species. 
The Edisto Island material compares well with material presently iden- 
tified as M. fossilis. Fossil localities include the Ashley River in South 
Carolina (Allen 1926), Ladds Quarry, Georgia (Ray 1967), and 
numerous sites in Florida (Webb 1974). 
Family Camelidae 
Palaeolama cf. P. mirifica (Simpson) — Pleistocene llama 
Material . — ChM.PV2411, right distal fragment of humerus; 
ChM.PV2409, right radius-ulna and associated carpals; ChM.PV2410, 
metapodial shaft fragment; ChM.PV2407, phalanx. 
Remarks.— The metapodial fragment and phalanx conform closely in 
size and morphology to Palaeolama mirifica from the Coleman II locality 
in Florida. But the two limb elements (ChM.PV2411, ChM.PV2409) 
seem larger and more massive than comparative P. mirifica material. 
Measurements taken from the radius-ulna are comparable to those 
recorded by Webb (1974) for P. mirifica (Table 3). The species has been 
reported from Florida (Webb 1974), Texas (Lundelius 1972), and the 
coast of Georgia (Frey et al. 1975). The record of Palaeolama at Edisto 
Island extends its geographic distribution northward.
