LICHENOPORA BUSKIANA, new name 



Plate 34, Figures 7, 8 



1875. Discoporella calijornica Btjsk, Catalogue Marine Polyzoa British 

 Museum, pt. 3, Cyclostomata, p. 32, pi. 30, fig. 5. 



In 1923 (p. 203) we noted that LicTienopora californica of Conrad, 

 1855, and of Robertson, 1910, was neither the species of Busk, 1875, 

 nor of D'Orbigny, 1852, and we preserved Conrad's name, D'Or- 

 bigny's specimen not having been figured yet. We now take the 

 occasion to change Busk's species to LicTienopora huslciana, new 

 name. Our determination is a Httle doubtful, for the specimen is 

 incompletely developed and very small, but it has the characters 

 cited by Busk in his diagnosis, "zoarium thick; fasciculi much raised 

 and biserial; mouths of cells less than the cancelli." The veinules 

 between the cancelli on the figure of Busk are here also quite 

 visible. 



It is interesting to discover in the Pliocene of Panama a species not 

 observed in the Gulf of Mexico, but which lives in the Pacific. In 

 addition to this one, we have already noted Callopora curvirostris 

 Hincks, 1881, Tremopora radicifera Hincks, 1881, and Hippopodina 

 feegensis Busk, 1884. The formation of the Isthmus of Panama 

 seems, therefore, quite recent. 



Occurrence. — Pliocene; Minnitimmi Creek, Bocas Island, Almirante 

 Bay, northwest Panama.

Genus DOMOPORA D'Orbigny, 1847 



DOMOPORA FLORIDA NA, new species 



Plate 30, Figures 5, 6 



The small specimen which we figure contains only two superposed 

 colonies. The center is concave and occupied by large polygonal 

 cancelli. The tubes are open on the circumference. They are adja- 

 cent and form little salient, indistinct, longitudinal lines separated by 

 polygonal cancelli of the same diameter. This specimen Vv^as fixed 

 on a nullipore. Our object in publishing this figure was to show 

 the persistence in the recent seas of the zoarial form observed fre- 

 quently in the ancient seas of the Cretaceous and Tertiary. We 

 have discovered another species of Domopora in the Philippines. 

 The extreme rarity of the material studied does not permit us, 

 unfortunately, to make a scientific study of the ancient genus 

 Domopora. 



Occurrence. — Albatross Station D. 2405, Gulf of Mexico; 28° 45' 

 00" N.; 85° 02' 00" W.; 30 fms.; gray sand, broken coral. 



Eolotype.— Cat. No. 7491, U.S.N.M.
