REPORT ON THE GASTEROPODA. 201 



15. Fusus valedictus, 1 n. sp. (PL XVII. fig. 7). 



Station 166. June 23, 1874. Lat. 38° 50' S., long. 169° 20' E. 200 miles west of 

 Cape Farewell, New Zealand. 275 fathoms. Globigerina ooze. 



Shell. — Strong, feebly ribbed, regularly spiralled, fusiform, attenuated, with a long 

 body whorl, a subscalar spire, a small mamillated apex, and a protracted snout. Sculpture : 

 Longitudinals — there are on each whorl 10 or 12 short oblique riblets, which do not 

 extend to either suture, and are rather flatfish elongated tubercles than ribs ; they are 

 parted by shallow open furrows ; down the spire they become feebler, and all but dis- 

 appear on the last whorl ; besides these riblets there are numerous coarsish lines of growth. 

 Spirals — the surface is scored with distinct equal flat threadlets, pretty equally parted by 

 flat shallow furrows of about three times their width ; of these threadlets there are 9 or 10 

 on the penultimate whorl ; they are absent immediately below the suture. Colour white, 

 but the shell is bleached. Spire high, subscalarly conical. Apex small, mamillary, the 

 extreme tip immersed; it consists of 2^ smooth rounded whorls. Whorls 8^ in all; they 

 are slightly carinated by the prominence of the tubercled riblets, shouldered and a very 

 little concave below the suture, and cylindrical, but to a very small extent contracted into 

 the lower suture ; the last is somewhat elongated, rounded, but hardly tumid, and with a 

 long contracted concave base. Suture linear, in a broad open depression. Mouth oval, 

 oblique, bluntly pointed above, and running out into an open, very oblique, longish canal 

 in front. Outer lip strong and blunt, very feebly scored within, with long narrow teeth ; 

 from its insertion it retreats very much, here it is flattish ; in the middle it runs straight 

 in the line of the axis. Inner lip concave to the beginning of the canal, where it is 

 angulated and has a twisted keel ; on the body there is a thin glaze, which becomes a 

 little thicker at the side of the canal. H. 2 in. B. - 85. Penultimate whorl, height 0"37. 

 Mouth, height 1*2, breadth 0-39. 



This species is like the young of Fusus mandarinus, Duclos, but is much more narrow and com- 

 pact, of many more whorls, more numerous riblets, and wants the many intermediate spiral threadlets 

 which lie in the interstices of that species ; the apex, too, is not nearly so large, and has fewer whorls. 

 It is a very much smaller species.

 Island and the Crozets. 1600 fathoms. Diatom ooze. Bottom temperature 34 - 2° F.

 prolonged into a short, small-pointed, lop-sided snout. Sculpture : Longitudinals — there
