Epitonium (Ferminoscala) ferminianum Datu. 
Plate 8, figure 8. 
Shell large, solid, acute, with eleven or more closely adherent whorls, of a livid 
flesh-color, fading to white, the terminal varix white; surface dull, not polished ; 
axial sculpture of numerous low, small, sharp lamellae, slightly more prominent 
before the suture in the last two whorls; these are reticulated by half a dozen 
prominent, flattish spiral threads with wider interspaces in which run much finer 
threads; the basal disk is also covered with close-set, very fine spiral threads, and 
the suture is laid on its posterior margin; aperture rounded, slightly patulous in 
the prolongation of the axis, and in the fully adult shell with a thick, white vari- 
cose peritreme bevelled away from the actual aperture to the thicker portion of 
the varix behind. Length of shell, 38; of last whorl, 21; diam. of disk, 15.5; of 
last whorl, 17 mm. 
U.S. 8. “ Albatross,”’ station 2804, in 27 fathoms, mud, Panama Bay, U. 8. N. 
Mus. 96,628. Also station 3391, in the Gulf of Panama, in 153 fathoms, mud, 
bottom temperature 55°.8 F.; station 2834, off Lower California, in 48 fathoms, 
mud, bottom temperature 56°.4 (figured type, U. 8. N. Mus. 96,818); and 
station 3034, in the Gulf of California, off Point Fermin, in 24 fathoms, tem- 
perature 63°.5. 
The fragment collected at station 3391 was the only specimen showing the 
fully mature varicose lip. 
I wrote a description of this species and had the present figure prepared about 
1892, but although I have a strong impression the diagnosis was published, I 
have mislaid the reference to it and so give a brief description. 
Epitonium (Ferminoscala) brunneopictum Datt, n. sp. 
Plate 8, figure 10. 
Shell slender, acute, pale brownish, with broad peripheral band and basal disk 
of darker brown, and about eleven whorls, exclusive of the (lost) nucleus; 
sculpture of the same type as in the preceding species with, between the sutures, 
three primary and about six secondary spirals beside the spiral striae; the axial 
lamellae are very small and sharp, regularly spaced, little raised and about 
thirty-six on the penultimate whorl, they appear as whitish lines on a brown 
background; basal disk sharply spirally threaded, little raised; aperture as 
figured, when fully grown probably with a thick varix. Length of shell, 37; 
of last whorl, 14; of aperture, 8; diam. of basal disk, 9; max. diam. 10 mm. 
U. 58.58. “ Albatross,” station 2835, in 53 fathoms, mud, off Lower California. 
U.S. N. Mus. 97,084. 
This and the preceding species present an assemblage of characters not pro- 
vided for in the existing series of sections proposed for members of this genus.
