Type-locality. — ^U. S. Fish Commission station 3346, off Tillamook 

 Bay, Oregon, in 786 fathoms, ooze; bottom temperature, 37.3° F. 



BORSONELLA CIVITELLA, new species. 



Shell fusiform, elongate, acute, of a pale buff color, of eight or 

 more whorls, the nucleus defective, the suture distinct, not appressed; 

 axial sculpture of (on the penultimate whorl, 9) short prominent 

 ribs conspicuous only on the periphery and obsolete on the later 

 part of the last whorl, the incremental Imes are also rather con- 

 spicuous; there is no spiral sculpture except a few faint lines on the 

 anal fasciole which is adjacent to the suture; in addition to the 

 above there are minute oblique striae often punctate, with wider 

 interepaces which cross the incremental lines almost at right angles; 

 these, hardly visible except under a lens, give the surface a vermi- 

 culate aspect; aperture rather narrow, the anal sulcus wide and 

 shallow, the outer lip strongly protractively arcuate, thin, simple; 

 inner lip with a thin wash of callus, pillar straight with a single 

 plait, throat yellowish, canal wide, straight; height of shell, 19; 

 of last whorl, 11.5; of aperture, 8; diameter, 6.5 mm. U. S. Nat. 

 Mus. Cat. No. 209034. 



Type-locality.— {]. S. Fish Commission station 4310, off Point 

 Loma, California, in 71 to 75 fathoms sandy mud. 



The plait on the pillar is mvisible from the aperture. 



LORA FIOSA, new species. 



Shell small, grayish white, acute, with a small subglobular nucleus 

 and six subsequent whorls moderately rounded and with a slight 

 shoulder; suture distinct, not appressed; spiral sculpture of (on the 

 penultimate whorl in front of the shoulder about 6) incised lines, 

 with wider mterspaces, overrunnuig the ribs; on the last whorl tliia 

 sculpture extends to the canal; axial sculpture of (on the last whorl 

 about 17) short rounded ribs extendmg from the shoulder, where 

 they are most prominent, over the periphery and obsolete on the 

 base; there are also fairly distinct incremental lines; aperture short, 

 wide, with a feeble anal sulcus and hardly differentiated canal; 

 outer lip thin, simple, inner lip erased; throat whitish; height of 

 shell, 9.75; of last whorl, 6; of aperture, 4; diameter, 4 mm. U. S. 

 Nat. Mus. Cat. No. 220399a.
