Epitonium (Ferminoscala) ferminianum Dall. 



Flate 8, figure 8. 



Shell large, solid, acute, mth 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 wliich 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 beliind. Length of shell, 38 ; of last whorl, 21 ; diam. of disk, 15.5 ; of 

 last whorl, 17 mm. 



U. S. S. " Albatross," station 2804, in 27 fathoms, mud, Panama Bay, U. S. N. 

 Mus. 96,628. Also station 3391, in the Gulf of Panama, in 153 fatlioms, mud, 

 bottom temperature 55°.8 J. ; station 2834, off Lower California, in 48 fathoms, 

 mud, bottom temperature 56°.4 (figured type, U. S. N. Mus. 96,818); and 

 station 3034, in the Gulf of California, oS" Point Fermin, in 24 fathoms, tem- 

 perature 63°. 5. 



The fragment collected at station 3391 was the only specimen showing the 

 fully mature varicose hp. 



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 Dall, n. Bp. 



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, wlicn 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. S. S. " Albatross," station 2835, in 5^ fathoms, mud, off Lower Califoniia. 

 U. S. N. Mus. 97,084. 



This and the preceding species present an assemblage of characters not pro- 

 vided for in tlie existing scries of sections proposed for members of this genus.
