Parisis ?brevis (D'Acliiardi) 



fisis brevis D'Achiardi, 1868, p. 75, pi. 1, figs, la, lb. 

 Isis brevis Reuss, 1869, p. 292, pi. 28, figs. 14-16. 



Reuss' specimens are clearly referable to Parisis, and his figures 

 correspond very closely with P. fruticosa Verrill. The identity of 

 Reuss' material with D'Achiardi's is still open to question. 



Horizon and locality: Terebratulinenschichten von San Martino 

 (Reuss); Sassello (Miocene); Castelgomberto (Oligocene) (D'Achi- 

 ardi) ; all Italy. 



Suborder HOLAXONIA Studer, 1887 



Family Plexauridae Gray, 1859 



Genus Eunicea Lamouroux, 1816 



Because doubtful species are excluded from consideration in the 

 subsequent designation of generic types, the usually accepted type 

 species of Eunicea {Gorgonia succinea Pallas, 1766; designated by 

 Kiikenthal, 1917, p. 335) is ruled out. Lamouroux himself consid- 

 ered Eunicea succinea "une espece douteuse." Inasmuch as no 

 other typo designation appears to have been made, I here select 

 Eunicea mammosa Lamouroux, 1816, as genolectotype of Eunicea 

 Lamouroux, 1816. 



Rumphella, new genus 



Plate 2,a,b 



Plexaurids with moderately thick branches often terminally clavate, 

 calyces low or absent, anthocodiae armed with a crown and points. 

 Base of axis secondarily enlarged to form a dense calcareous mass, 

 especially in old specimens. Cortical spicules in the form of spindles 

 and clubs; the clubs are symmetrical wart-clubs only, derived from 

 capstans. There are no long rods as in Hicksonella Nutting; no 

 thorny clubs as in Psammogorgia Verrill; no large spheroids as in 

 Ewplexaura Verrill; no foliate clubs and torches as in Plexaura 

 Lamouroux. Spicules of the inner cortex never purple or lavendar. 



Type species: Plexaura aggregata Nutting, ldlOsi= Rumphella 

 aggregata, new combination (pi. 2,a,b). Sj'^ntype, USNM 43461, 

 Flores Sea and envhons, station data illegible (Siboga Exped.). 



Remarks: Also referable to Rum'phella are Gorgonia antipathes 

 variety /3, Esper, 1792 (including also Plexaura antipathes Klunzinger, 

 1877 and Euplexaura antipathes Hiles, 1899) and Gorgonia suffruticosa 

 Dana, 1846. Esper's, Klunzinger's, and Hiles' specimens seem to 

 represent a shigle species in all probability identical with the Coral- 

 lium nigrum of Rumphius and the Gorgonia antipathes of Linnaeus.
