LENGTH IN MILLIMETERS 



Fig. 58. — Agassisia porifera (Ravenel). Height of test relative to length. 



ECHINOCARDIUM GOTHICUM (Ravenel) ? 

 Plate 11, figure 4 



Remarks. — There are 29 fragments that appear to belong to this 

 species of Ravenel (1848, p. 4). The petal arrangement and fascioles 

 are identical to Cooke's (1959, pi. 33, figs. 7-10) figured specimens. 

 Without having any complete specimens it is not possible to know the 

 shape of the test, and these fragments can be referred only provi- 

 sionally to this species. 



Occurrence. — Tamiami formation (barnacle-echinoid-oyster facies), 

 loc. 26, 32. 



Figured specimen. — U.S.N.M. 648144, loc. 32.
