Shell high, narrow, conical, with a small apex, a contracted, conical base, and a longish narrow snout; carinated, ribbed, with spiral threads, pale buff. Sculpture: the whole surface is frosted over with microscopic tubercles. Longitudinals: there are on the last whorl 16 narrow, raised, dextrally convex, and rather oblique ribs; originating at the angle of the whorls, where they are a little tubercled and swollen; they are parted by furrows of about the same breadth as themselves; they die out across the base, and do not appear on the snout. There are about 13 on the penultimate whorl, and they diminish rapidly up the spire; the lines of growth are exceedingly faint and few, but sharp; they are most visible in the sinus-area and on the snout. Spirals: the suture is marginated above by a minute thread, which lies at the bottom of the superior whorl. The sinus-area is bare. Slightly above the middle of the whorls is the strong angulation, to which the prominence of the ribs originating at this point gives great additional sharpness and distinctness. From this to the point of the shell the surface is scored by rounded and prominent threads ; of these there are three, pretty equal, on the earlier whorls, the third forming the supra-sutural margination; a fourth appears on the penultimate whorl, and 19 or 20 on the last, with one or two fainter ones between; the first two are feebler and closer set than the rest; on the body they are rather distant, on the front of the shell rather stronger and close set. Colour a pale buff, but not improbably white when fresh. Spire conical, subscalar in consequence of the prominence of the keel. Apex is small, roundedly sharp, consisting of 3,25 carinated, but otherwise perfectly smooth, whorls, which form a short compact little cone, of which the extreme tip is a little obliquely flattened down on one side. Whorls 10 in all; there is a drooping and very slightly concave shoulder below the suture; the greatest breadth is at the keel, below which the whorls begin faintly, and with a very slightly convex profile, to contract into the inferior suture; the last contracts rather rapidly into a short conical base, running out into a narrow, straight, somewhat one-sided, and not very long snout. Suture invisible but for the marginating threads above and below it. Mouth club-shaped, being pointedly ovate above, and running out below into a well-marked canal. Outer lip concave below the suture and angulated at the keel; it is convex in its sweep to the edge of the canal, from which it runs directly and obliquely to the rounded and open point of the pillar. In leaving the body it retreats at once to the right to form the rounded sinus, which has an excessively short upper side, but becomes large (though hardly deep) from the great forward wing-like sweep of its lower margin, whose course is quite independent of the ribs; toward the edge of the canal this curve again retreats to the point of the shell. Inner lip is a thin narrow glaze margined with a minute furrow; it is oblique, but scarcely convex across the body, direct on the short pillar, and cut off with a long slope to the point of the canal, its edge being narrow, rounded, and scarcely at all twisted. H. 0,43 inch. B. 0,17 inch. Penultimate whorl, height 0,07 inch. Mouth, height 0,2 inch, breadth 0,08 inch.

Description. Shell high, slender, white, reaching 14.09 mm. Protoconch with 3 whorls, light yellow, Protoconch 1 granulose. Protoconch 2 with a spiral keel on its lower portion and a delicately nodulose suprasutural cord. The spiral keel itself is sculptured with tiny slanted riblets, giving it the appearance of a braid. Clear-cut protoconch-teleoconch transition. Teleoconch with 7 middle-angled whorls. Sculpture consisting of 18 axial ribs (on the 7th whorl), beginning on the shoulder and extending below it. Spiral sculpture consisting of 5 thin equidistant cordlets that spread from the shoulder to the lower suture. Area between the shoulder and the upper suture smooth. The entire shell surface is covered by growth scars and a rather thick, spirally arranged granulation, thinner at the protoconch and the first whorl of the teleoconch. Suture shallow. Base lightly convex, with slight inflection to form the siphonal canal, with about 17 evenly spaced spiral cords. Labial sinus deep, curved at the zone between the shoulder and upper suture. Inner lip almost straight, reflected over the parietal wall. Outer lip crenulated by spiral ornamentation. Siphonal canal long and narrow. Aperture elongated.

Geographic distribution. Southwest Atlantic: Pernambuco, northeast Brazil (Watson, 1886); - Bahia, Brazil (Absalao et al., 2005); West Indies and Brazil, Amapa to Rio de Janeiro (Rios, 2009); Campos Basin, southeast Brazil (this paper). From 27 m (Rios, 1994) to 750 m (this paper).

Absalao et al. (2005: 30) proposed to transfer Granoturris rhysa (according to Rosenberg, 2009) or Kurtziella rhysa (according to Rios, 2009) to the genus Corinnaeturris, arguing that the protoconch with axial riblets and 3-4 spiral threads typical of Kurtziella is not observed in this species, which has a macroscopically smooth protoconch with a spiral keel present from the second whorl. However, Granoturris is characterized by a protoconch that may have "a few weak axial riblets on the last turn, followed by a weak submedian peripheral keel" and "the anal sinus shallow or absent" (Fargo, 1953: 394); whereas C. rhysa has a deep anal sinus. Moreover, Granoturris padolina Fargo, 1953 (Fargo: pi. 23, Figs. 5, 5a), the type species of Granoturris, has a spire that is taller than the body whorl and a subcylindrical profile, whereas C. rhysa has a spire that is shorter than the body whorl and a biconic profile. Therefore, Granoturris proves to be a dubious taxonomic placement for rhysa. However, C. rhysa fits the characters of Corinnaeturris well.
