316 REPORT ON ALBATROSS MOLLUSCA DALL. 



earlier whorls of up to fourteen little raised hardly flexuous transverse 

 waves extending clear across the whorls, rounded, equal throughout 

 their leugth, and separated by shallow slightly wider interspaces ; tbis 

 transverse sculpture becomes gradually fainter, and entirely obsolete 

 on the last whorl, which in the adult seems only marked by the tine and 

 slightly irregular incremental lines which give to the thin, smooth, pale 

 brown, and slightly fibrous epidermis a silky appearance; spiral sculp- 

 ture of numerous very fine, close, half obsolete grooves or scratches, and 

 six or seven deeper, stronger grooves encircling the canal; whorls 

 mostly flattened, the last slightly rounded; suture distinct, appressed; 

 aperture white, the outer lip thin, sharp, with no lira? in the typical 

 specimen; column with three plaits, the auterior one faint; canal shortj 

 nearly as wide as the aperture, hardly recurved; siphonal fascioie dis- 

 tinct; soft parts whitish, with no operculum. Longitude of shell 

 (nuclear whorls lost), 35; of last whorls, 17 ; of aperture, 12; maximum 

 latitude of shell, d 0101 . 



Hab.— One living specimen, at Station 2628, 100 miles southeast by 

 south half south from Cape Fear, North Carolina, in 528 fathoms, yellow 

 mud; bottom temperature 38°.7 F. 



The soft parts are so contracted that they could not be extracted 

 without breaking the shell. This species looks a good deal like a 

 Terebra in form. None of the described species at all resemble it. 



Mitra Hanleyi Dobrn. 



This species was dredged in 20 fathoms, 90 miles southeast from Cape 

 San Eoque, Brazil, at Station 2758. 



Subgenus CONOMITRA Conrad. 



Conomitra intermedia sp. nov. 



Plate v, Fig. 3. 



Shell elongated, white, polished, fusiform, with a large smooth shelly 

 nucleus and seven or more whorls ; suture distinct, not channeled ; 

 whorls with a slight shoulder a short distance in front of the suture, on 

 which are a series of short,. narrow, irregularly spaced little-elevated 

 riblets, which, except on the earliest whorls, become almost immediately 

 obsolete; other transverse sculpture only of incremental lines; spiral 

 sculpture of microscopic spiral strise, often obsolete, and a few fine faint 

 threads on the canal; aperture narrow, elongated; outer lip (broken) 

 thin, not internally lirate; pillar and body with a thin glaze of polished 

 enamel; plaits four, very horizontal, the posterior the highest; pillar 

 straight, attenuated in front; canal short, hardly differentiated from 

 the aperture; maximum altitude of shell, 15.5; maximum latitude, 5.7 mu \ 



Hab. — IT. S. Fish Commission Station L!750, off St. Bartholomew, 

 West Indies, in 496 fathoms, sand; bottom temperature 44°.4 F. 



This curious little shell very nearly bridges the gap between Cono- 

 mitra and Mitra. The large inflated nucleus is a common characteris-
