Type-locality. — U. S. Fish Commission station 4515, off Point Pinos, 

 California, in 198 to 495 fathoms mud and shell. 

 This is closely related to N. tenuisculpta Carpenter. 



TYPHIS LATIPENNIS, new species. 



Shell large for the genus, solid, heavy, with four varices to a whorl, 

 the tubes retractive, nearer the preceding varix, and about six whorls, 

 the nucleus rounded, small; suture obscure, the spaces between it and 

 the shoulder excavated ; sculpture of a keel at the shoulder and lines 

 of growth elsewhere ; terminal varix wide, with a prominent retractive 

 spine at the shoulder and the outer edge recurved; aperture ovate, 

 entire, canal (defective) closed, not very long; height of shell (esti- 

 mated), 30; of spire, 8; of aperture, 7; maximum diameter, 24 mm. 

 U. S. Nat. Mus. Cat. No. 96653. 



Type-locality. — U. S. Fish Commission station 2822, off Lower Cali- 

 fornia, in 21 fathoms, sand. 



Although the specimen is defective about the end of the canal, it 

 is obviously distinct from either of the species yet described from this 

 region. 



CORALLIOPHILA STEARNSIANA, new species. 



Shell large, solid, white, of about six very rapidly enlarging whorls, 

 with an acute apex, the nucleus decorticated; suture distinct, very 

 deep and narrow, but not channelled; axial sculpture of about 16 

 rounded ribs with subequal interspaces, chiefly prominent on the 

 periphery, much obscured by the spiral sculpture and obsolete on 

 the last half of the last whorl; spiral sculpture of (on the last whorl) 

 in front of the suture about 15 close-set small cords not undulated by 

 the ribs, next follow 10 or more much coarser ribs of irregular promi- 

 nence with subequal interspaces carrying each an intercalary thread, 

 all with the rasp-like lamination peculiar to the genus and extending 

 to the verge of a narrow, axially striated umbilicus; aperture wide, 

 rounded, the outer lip simple, the body with a lamina of w^hite enamel, 

 the pillar lip short, with a Trichotropis-like notch at its base; height 

 of shell, 23; of last whorl, 18; of aperture, 15; diameter, 24 mm.

COBALLIOPHILA (PSEUDOM UREX) KiNCAIDl, new species. 



Shell fusiform, dirty white, with about six shouldered whorls, the 

 nucleus decorticated, the suture deep, very narrow; axial sculpture 

 of nine rather sharp vertical ribs extending from the suture to the 

 canal with wider mterspaces ; spiral sculpture of (on the penultimate 

 whorl eight) strong subequal cords, with narrower deep interspaces 

 covering the whole shell, all furnished densely with short guttered 

 lamination as usual in the genus; aperture ovate, outer lip simple,
