1872. Pustulopora proboscideoides Smitt, Floridan Bryozoa. Koogl. Svenska 

 Vetenskaps-Akademiems, vol. 10, p. 11, pi. 4, figs. 26, 27. 



Affinities. — Smitt compared his species with a species of Gabb and 

 Horn, 1862 (p. 170, pi. 21, fig. 60a), found in the Eocene of Alabama. 

 The figure of the American authors represents a very small fragment, 

 and it is very difficult to be certain of the identification, since we 

 have not discovered an analogous specimen in our immense amount 

 of material from Eocene and Miocene localities. 



Our specimens are quite similar to the figures of Smitt. 



Occurrence. — Recent: Florida, 110 meters (Smitt). Pliocene: Min- 

 nitimmi Creek, Bocas Island, Almirante Bay, Panama. 



Plesiotypes. —Cett. No. 70839, U.S.N.M.

 skaps-Akademiens Handlingar, vol. 10, p. 11, pi. 5, figs. 28-30. 



The synonymy of this species is in controversy, but as our materials 

 are not sufficient we have abstained from making any criticism. Our 

 specimens conform to Smitt's figures. 



We have been rather fortunate to discover a base which we have 

 figured. Up to the present the species appears restricted to America 

 around Florida.

Variations. — Most of our specimens correspond well to Smitt's fig- 

 ures; the tubes, nonadjacent, are arranged in oblique rows to the
