Shell fusiform, with rather long, conical spire and rather long curved canal. Ape.x eroded, 

 remaining whorls 9, slightly excavated below the suture, convex at the periphery, suture 

 conspicuous but not deep. Upper whorls with a few broad concentric ribs, disappearing on the 

 5''^ whorl. Spiral sculpture consisting of numerous lirae, which are subecjual on the upper ex- 

 cavated part of each whorl, and lower on alternating with stronger ones, so that between each 

 2 stronger lirae, runs a smaller one, in many cases with a very fine one, on one or on both 

 sides; the lower part of last whorl, has nearly regularly 3 thinner lirae between 2 stronger 

 ones; this spiral sculpture is crossed by stronger and finer concentric striae, producing a granular 

 appearance of the whole surface, also on the backside of canal, which is curved finst to the 

 left, then to the right side. Aperture oval, sharply angular above, the last whorl being appressed 

 to the penultimate one; canal rather broad, peristome inconspicuously crenulate; interior of 

 aperture smooth. Colour dirty white, shell covered in part by a brown epidermis ; interior of 

 aperture porcellaneous white. Operculum typical.

The radula has a median tooth (M) with a tricuspid base, the median cusp being the 

 longest, the base is as usual broader behind, the anterior margin is notched; the laterals (i) are 

 broad, strongly curved, with 9 denticles, of which 8 are subequal in length, the most proximal 

 one is much shorter, moreover I see in many teeth an intermediate cusp ; the distal margin is 

 angular below, but I think this angle should not be considered as a cusp. 



This species is nearly allied to F. siibangulahis v. Martens (Die beschalten Gastrop. der 

 deutschen Tiefsee-Exp. 1898 — 1899, p. 102, PI. 2, fig. 11) and I have repeatedly compared 

 the Siboga specimens with a type, received for comparison from the Berlin-Museum, as many 

 of the differences seem to be only gradual. The new species is not angular, the concentric 

 ribs occupy only the uppermost whorls, the apierture is broader, the canal much more curved. 

 The character which induced me to describe the species as new, is however the different 

 sculpture, which practically consists of alternately stronger and finer lirae, in F. szibangulahis 

 the sculpture is more diversified, as between 2 stronger lirae, I see 6 and even 8 thinner ones, 

 while there are by close examination only 3 intermediate ones in the new species ; the spiral 

 sculpture is consequently much more regular and less coarse ; in the new species the lirae are
