NEW ANTLLLEAN MOLLUSKS — REHDER 201 



Other Antillean species that belong in Pusia are the genotype P. 

 sulcata Gmelin (=microzonias Lamarck), histrio Reeve, trophonia 

 Dall, and albocincta C. 13. Adams. Three other West Indies species 

 that belong here, but have stronger spiral sculpture, are P. pulchella 

 Reeve, variata Reeve, and dermestina Lamarck. 



PUSIA EPIPIIANEA, new species 



Plate 20, Figure 14 



Shell in general similar to P, hendersoni but larger (apex broken, 

 but 9 postnuclear whorls remaining) , with spiral sculpture somewhat 

 more obsolete and the subperipheral white band more conspicuous; 

 below the band the shell is chocolate-brown and above the white band 

 the color is chocolate-brown between the axial ribs, fading to pinkish 

 on the ribs and becoming yellow just below the suture; on the pen- 

 ultimate whorls the color is in general fainter. 



The type, U.S.N.M. No. 414278, measures: Height, 23.7 mm.; 

 breadth, 9 mm. It was dredged in 15 fathoms off Tortugas, Fla., by 

 John B. Henderson, Jr. 



Genus PUSIOLINA Cossman, 1921 



This group, proposed as a substitute for Pusiola Monterosato, 1917, 

 not Wallengren, 1863, with the type tricolor Gmelin from the Med- 

 iterranean, was considered by Monterosato to be a genus distinct 

 from Pusia. Thiele, however (Handb. Syst. Weichtierk., vol. 1, 

 p. 337, 1929), gave it only sectional value under Pusia. An examina- 

 tion of the nuclear whorls of these two groups forces us to accept Mon- 

 terosato's dictum and Pusiola with its bulbous nucleus of one to one 

 and a half whorls must be restored to generic rank, distinct from 

 Pusia, which has a narrowly conical, straight-sided nucleus of about 

 four whorls. Mitra hanleyi Dohrn and genvmata Sowerby from the 

 Caribbean region may be placed here, agreeing in general character 

 with the genot3/pe but having four columella! 1 folds instead of three. 

 Until the radular characters are elucidated these species had better 

 not be separated solely on the difference in the number of folds. Here 

 we may also place the following new species. 



PUSIOLINA ^RfiSTA, new species 



Plate 20, Figure 1 



Shell rather large for the genus, narrowly ovate. Nucleus bul- 

 bous, consisting of 1% convex whorls, the first V/ 2 whorls brown, 

 the last half gradually becoming glassy gray. The following 5% 

 whorls slightly convex, subsuturally somewhat flattened, distantly 

 axially ribbed, and only very obscurely axially grooved. Color straw
