MOLLUSCAN FAUNA FROM DELAND* 
119 
The basal member of this section furnished the fossils listed below : 
Melampus lineatus Say. 
Terebra concava Say. 
Olivella mutica Say. 
Oliva liter at a Lam. 
Fiilgur pyriformis Conrad. 
Littorina irrorata Say. 
Leda acuta Conrad. 
Area transversa Say.” 
A later small collection about }i mile north of the railroad at 
Orange City was not reported in the Second Annual Report of the 
Florida Geol. Survey. 
A comparison of the faunas obtained respectively Fl mile north 
and south of Orange City with that near DeLand, listed in this 
paper, shows a very close relationship and probably represents 
nearly if not quite the same geological horizon. Of twenty forms 
collected near Orange City, fifteen are also found at DeLand. 
The following species, identified by Dr. T. W. Vaughan, were 
found eleven to seventeen feet below the surface one-half mile ( + ) 
south of DeLeon Springs Station, Fla.* 
Marginella contracta Conrad. 
Terebra dislocata Say. 
Oliva literata Lam. 
Melongena corona Gmel. 
Crepidula aculeata Gmel. 
Crepidula convexa Say. 
Crepidula plana Say. 
Cryptonatica pusilla Say. 
Area transversa Say. 
Area ponder osa Say. 
Area limula, var. platyura Dali. 
Area plicatura Say. 
Pecten gibbus Linn. 
Carditamera arata Conrad. 
V enericardia tridentata Say. 
Phacoides multiline afus T. and H. 
Phacoides waccamensis Dali. 
Phacoides radians Conrad. 
Cardium robustum Solander. 
Cardium isocardia Linn. 
Venus campechiensis Gmel. 
Chione cancellata Linn. 
Mulinia lateralis Say. 
Corbula inaequalis Say. 
Geologic Horizon — “Pliocene (compare Dr. Dali’s previous reference to 
Miocene at DeLeon Springs, Wag. Free Inst. Sci.)” (Vaughan). 
About 53 per cent of the species in this and other collections 
from DeLeon Springs occur also at DeLand.
