4. OFF RIO DE JANEIRO. 



I. Turris fornwsissima n. sp. PL II, tig. 10. 



Shell elongate, fusiform, white, excepting a reddish keel below the suture, and a 

 faint reddish zone below the convex part of the body-whorl ; whorls 13 ? ; apex broken 

 oft': remaining volutions slightly convex, with three spiral keels, of which the central 

 one round the middle is thicker than the other two ; between the keels the shell is 

 sculptured with oblique divergent lines of growth, and a spiral thread in each inter- 

 carinal space ; the suture is also bordered above by a spiral thread ; last whorl with 

 five principal keels, and numerous other less pronounced lirse below them. The strong 

 raised lines of growth become much finer on the rostrate part of the whorl ; aperture 

 oval above, produced anteriorly into a long, narrow, straightish canal; labrum thin, 

 shortly siuuated above at the principal carina ; columella straightish, smooth. 



Length, if complete, about 26 mm. ; diameter, 7 ' 5. Aperture, with canal, 1 1 ' 5 mm. 



Station 42, off Rio de Janeiro : 40 fathoms. 



( hily two specimens. Allied to T. antillarum (Crosse),* but differing apparently 

 in the intercarinal sculpture. The uppermost keel also is not so strong as the central 

 one, whereas in the West Indian species they are described as equal. 



2. Dritlin braziliensis, u. sp. PL II, fig. 11. 



Shell slender, fusiform, light brown, with whitish nodules; whorls 11, slowly 

 increasing, the two apical smooth, forming a large rounded protoconch, the rest 

 longitudinally obliquely costate, the costae most prominent at the middle of the whorls, 

 where they are crossed by two spiral line, which form transversely elongate nodules 

 upon them ; a wavy carina passes along the upper margin of the whorls, and a finer 

 thread borders the lower suture. On the body-whorl the cost* are produced down- 

 wards below the middle, but do not extend quite to the end of the rostrum ; the 

 spirals are about eighteen, and about seven of the upper ones are more or less nodulous 

 on crossing the costfe, the rest below are finer and smooth ; between the nodulous 

 lirse, both on the spire and on the last whorl, there are fine thread-like lines, and the 

 whole surface exhibits delicate wavy growth-striae ; aperture brown within, not quite 

 one-third the length of the shell ; labrum thin at the edge, distinctly sinuate below the 

 sutural keel, and having a costa or varix, larger than the other costse, on the outside ; 

 eolumella straightish, covered with a pale callus, formed into a tubercle at the sinus. 



Length, 21 mm. ; diameter, 6. 



Station 42. off Rio de Janeiro : 40 fathoms.
