only 11 whorls and 43 mm. long, or-in 1 with 17 whorls 
and 7°99 mm. long. 
Locality.—Type from 55 fathoms off Cape Borda, with 
56 others in good condition and about 90 poor; also in 62 
fathoms, 2 poor; also off Beachport in 40 fathoms, 2 good; 
in 110 fathoms, 4 good and 5 moderate; in 300 fathoms, 3 
poor: cif Cape Jaffa in 130 fathoms, 2 moderate; in 300 
fathoms, 1 poor. Its habitat would therefore appear to be 
in 50 fathoms, extending up to 40 and down to 110. 
Obs.—Although this shell is dextral it has been placed in 
the genus Triphora, because it has the three apertures in 
its body-whorl. But for this it would have been called a 
Cerithiopsis, and if immature it would have been placed in 
this genus. In the Bull. Mus. Compar. Zool. of Harvard 
Coll., vol. xviil., “Blake” Dredging, xxix., Report on the 
Mollusea, 1889, part 2, p. 242, W. H. Dall writes: —“There 
are probably,” in Triforis, “some dextral forms, though such 
are apt to be referred to Cerithiopsis.” This suggestion is 
the justification for calling my new species a Triphora. Sub- 
sequent examination of the animal may settle its final gen- 
eric location. 
EUTriphora epallaxa, n. sp. Pl. xxii., fig. 1. BLS 
Shell dextral, elongate-conical in the earlier half, cylin- 
drical in the later. Protoconch absent. Suture indistinct, 
minutely appressed. Whorls 18, flat, with two spiral rows 
of tubercles, axially alternating, much larger in the lower 
row; with a faint spiral cord joining the tubercles. The last 
whorl has its aperture round, projecting as a free tube, with 
a thin expanded border, also two other tubes—one standing 
out from the centre of the base, the other immediately below 
the suture of the penultimate whorl. The base is flatly con- 
vex and is slightly margined by the lower row of tubercles, 
which then passes between the two tubes and fades out on 
the dorsum of the projecting trumpet-shaped apertural tube. 
The upper row of tubercles ends at the base of posterior tube. 
Dim.—ULength, 79 mm.; width, 1°7 mm. ; including the 
projecting aperture, 2 mm. 
Locality.—130 fathoms off Cape Jaffa, 2 dead. 
Diagnosis.—It resembles 7. devia in being dextral, in 
its general shape, and in having three well-formed tubes, but 
is plainly distinguished by the two rows of alternating 
tubercles. 
Triphora subula, n. sp. Pl. xxiii, figs. 5 and 6. 
Shell sinistral, elongate-subulate-pyramidal. Protoconch 
of 34 turns; the first has two high, narrow, smooth, rounded
