external sculpture within; inner lip very slender, decidedly curved and 

 reflected; free only at the extreme anterior portion, the rest ap- 

 pressed ; parietal wall glazed with a thin callus. 



The type and two specimens, Cat. No. 187054, U.S.N.M., come 

 from Port Alfred (Coll. No. 592). The type has nine postnuclear 

 whorls, and measures: Length, 4.2 mm.; diameter, 1 mm. 



TURBONILLA (CARELIOPSIS) CARIFA, new species. 

 Plate 20, fig. 4. 



Shell small, elongate-conic, semitranslucent, bluish-white, nuclear 

 whorls, at least two, large and smooth, forming a depressed helicoid 

 spire, which is a little more than half obliquely immersed in the first of 

 the succeeding turns. Postnuclear whorls well rounded, feebly shoul- 

 dered at the summit, marked by quite regular, equal and equally 

 spaced, fine spiral lirations, of which 9 occur upon the first and second, 

 10 upon the third, and 11 upon the penultimate turn between the 

 sutures. Suture decidedly constricted. Periphery of the last whorl 

 well rounded. Base moderately long, very narrowly umbilicated, a 

 little less strongly rounded than the space between the sutures, marked 

 by about 11 spiral lirations of about the same strength and spacing 

 as those occurring on the spire. In addition to the spiral sculpture, 

 the whorls are marked by exceedingly fine, decidedly retractively 

 slanting lines of growth. Aperture moderately large, oval; posterior 

 angle obtuse; outer lip thin, showing the external sculpture within; 

 inner lip strongly curved, very slender, reflected over and attached 

 to the body whorl, except the extreme anterior portion, which is free; 

 parietal wall covered by a thick callus. 



The type, and another specimen, Cat. No. 250390, U.S.N.M., comes 

 from Port Alfred (Coll. No. 1263). The type has five postnuclear 

 whorls, and measures: Length, 2.1 mm.; diameter, 0.7 mm. 



TURBONILLA (MORMULA) CIFARA, new species. 

 Plate 16, fig. 5. 



Shell large and robust, elongate-conic, bluish white. Nuclear 

 whorls decollated. Postnuclear whorls slightly rounded, roundly 

 shouldered at the summit and weakly contracted at the suture, 

 marked by rather strong, somewhat irregular, slightly retractive, 

 axial ribs and an occasional vanx, marking the fusion of a number 

 of ribs. The varices are irregularly disposed. Of the axial ribs, 22 

 occur upon the first and second, and 20 upon all the remaining turns 

 but the penultimate, which has 22 ; on this turn they are rather irreg- 

 ularly disposed and less strongly developed. In addition to the axial 

 ribs the whorls are crossed by weakly incised spiral lines, which are of 

 somewhat varying strength. There are probably 50 of these between 

 the sutures. These lines and the feeble lines of growth between the
