^ TERTIARY FAUNA OF FLORIDA 



Two other forms have been described which are referable to this genus, 

 though possibly not distinct from each other. Coralliopliaga Bryani Clark, 

 Bull. U. S. Nat. Mus. No. 141, p. 73, pi. xv., figs. 2a-b, 1896, from Pamunkey 

 Neck, Virginia, should, strictly speaking, be called 0. Briani, since the collector 

 for whom it was named spelled his name in this fashion ; it is a shorter, higher, 

 and more equilateral shell than the Claiborne species, but appears to agree 

 better with Coralliopliaga prima Harris, Bull. Pal., ii., p. 252, pi. xiii., figs. 

 4, 4a, 5, 1897. The latter is from the Chickasawan or Lignitic Eocene of 

 Hatchetigbee Bluff, Alabama, and may also, according to Professor Harris, be 

 found at Wood's Bluff. 



The Coralliopliaga arata of Conrad (Fos. Tert. Form., p. 20, pi. v., fig. i) 

 is a species of Carditamera. The Cypricardia pedroana of Cooper (Bull. Cal. 

 State Mining Bureau, No. 4, p. 25, 1894) is probably a Calyptogena; it is from 

 the Neocene of Los Angeles, California. The original Petricola pedroana of 

 Conrad (Pac. R. R. Reps., v., p. 324, pi. iii., fig. 24, 1856), which by some 

 inadvertence has been identified with the former, is almost certainly only an 

 imperfect specimen of Venerupis lamellifera Conrad. 



The above comprise all the American Tertiary species which I have been 

 able to find referred to this general group. 



So far as known Trapezium and Coralliopliaga are not represented in the 

 recent fauna of the west coast of America, the californiciim Conrad being an 

 Indo-Pacific shell described as Californian by an error of labels.
