Plate 3, fig. 6. 



Shell fusiform, varying in ground color from lavender to orange or 

 even light brown. The shoulder usually is dark brown, while the rest 

 is lightly dotted with the same color. Extreme apex of nucleus decol- 

 lated; the first turn remaining is depressed and smooth. Postnuclear 

 whorls appressed at the summit, strongly, slopingly shouldered. The 

 shoulder, occupying the posterior half of the space between the sutures, 

 is marked by about fifteen unequally developed and unequally spaced, 

 punctate, spiral striations. Anterior half of whorls between the 

 sutures ornamented with feebly expressed, low, broad riblets, which 

 terminate at the anterior edge of the shoulder, where they appear as 

 slight tubercles. Of these, 17 occur upon the last turn. Rostrum 

 and posterior half of base finely, evenly, spirally Urate, the lirations 

 being developed at the insertion of the columella. Posterior angle of 

 aperture acute; columella sigmoid. 



The type, Cat. No. 187020, U.S.N.M., came from Port Alfred (Coll.

COLUBRARIA ALFREDENSIS, new species. 

 Plate 4, fig. 5. 



Shell elongate-conic, white, banded and lined with rust brown. A 

 series of short protractive streaks extend from the summit down on 

 the posterior fourth of the whorls. The streaks are about one-half as 

 wide as the spaces separating them. A spiral line of interrupted 

 dashes extends about the whorls a little posterior to the sutures, while 

 a broad dull rusty belt covers the anterior half between the sutures 

 and another, equally wide, the middle of the base. In addition to these 

 decided markings there are others less strongly denned, all of varying 

 shades of rust brown. Nuclear whorls decollated. Postnuclear 

 whorls moderately rounded, appressed at the summit and slightly 

 constricted at the sutures, marked by low, poorly defined, and irregu-
