608 REV. E. BOOG WATSOlSr ON THE 



riblets, whose course is from right to left ; they extend to the 

 whole base ; at irregular intervals one of these swells to a varix. 

 Spirals — there are similar, but smaller, more numerous, and closer- 

 set spirals, over which the longitudinal ribs rise. Colour porcel- 

 laneous white. Spire high, narrow, conical. Apex consists of 4| 

 hardly rounded, glossy, conical whorls, parted by a scarcely im- 

 pressed suture, and rising to a very minute rounded tip. Whorls 

 10 in all, convex, of regular increase; the last is small, with a well- 

 rounded base. Suture rather deeply impressed, obliq[ue. MoutJi 

 encircled with a strong varix, a little oblong, slightly oblique in 

 both its planes. Outerlip well arched, rounded, contracted above, 

 patulous in front. Inner lip narrow, thick, continuous with the 

 outer lip. H. 016. B. 005. Penultimate whorl, height 0-02. 

 Mouth, height 0-04, breadth O'OS. 



This is a peculiarly narrow species, of a rather remarkable 

 style of sculpture. 



3. SCALAEIA ACTJS, n. sp. 



St. 73. June 30, 1873. Lat. 38° 30' IS"., long. 31° 14' W. W. of 

 Azores. 1000 fms. Glohigerina-oozQ. Bottom temp. 39°'4 P. 



Shell small, compact, long, sharp, solidly ribbed, deeply su- 

 tured, with no spiral markings whatever, but a strong thread on 

 the rounded base. Sculpture. Longitudinals — there are on the 

 last whorl about 17, and on the first regular whorl about 15, 

 strong, raised, rounded ribs, which cross from suture to suture in 

 the line of the axis, and extend, though less strongly, to the base. 

 Spirals — there are none except one sharpish thread, which comes 

 out exactly at the upper corner of the mouth, and encircles the 

 base. Colour ivory-white. Spire high, narrow, conical. Apex 

 consists of three brownish-yellow, glossy, broad, cylindrical 

 whorls, of which the first is very short and rounded, the second 

 short and slightly conical, and the third high and cylindrical; 

 they have very fine, microscopic, hardly raised, flexuous, longi- 

 tudinal threads, and still finer spirals. Whorls 12 in all, very 

 much constricted at the suture both above and below, and some- 

 what flattened in the middle ; after the apex they are of very 

 slow and regular increase ; the last is smallish, with a rounded 

 base, within the contraction of which lies the basal bread. Su- 

 ture wide and deeply impressed, oblique. Mouth broken. H. 

 0-22. B. 0'06. Penultimate whorl, height 0-037. Mouth, height 

 0-044, breadth 004. 



There is another Scalaria from St. 122, ofif Pernambuco, 350 

 fms., which extremely resembles this, but is quite distinct, being
