REPORT OX THE GASTEROrODA. 197 



This very beautiful little shell is probably not full-grown, but possesses very marked features in 

 the short conical spire, sharp stellate keel, and enormously long snout. The only form which 

 seems to approach it is the Fusus spiralis, Ad., which has a curious geminately carinated and 

 flattened form of whorls and a long canal ; but the keel is median, the suture wide and deep, and 

 the apex is broad and blunt, while the spire is much less broadly conical.

Station 164b. June 13, 1874. Lat. 34° 13' S., long. 151° 38' E. Off Sydney. 

 410 fathoms. Green mud. 



Shell. — Kather thin, chalky to poreellanous, pale, oval, with a high scalar spire made 

 up of small sharp-flanged whorls, with a mamillate apex and a very long fine suout, down 

 which from the round mouth runs a thread-like cleft. Sculpture: The surface is scored 

 with extremely sinuous fine lines of growth formed by the subimbricated edges of scarcely 

 raised lanielke. Spirals — in the middle of each whorl is a sharp keel, which runs out 

 into an excessively sharp, prominent, compressed, and upturned flange ; though so sharp 

 and compressed, this flange is really double, and consists of a multitude of very minute 

 hollow arches, imbricated on one another. On the base of the body-whorl, coincident 

 with the upper corner of the mouth, is a small cord-like keel closely beset with minute 

 arched points. The upper third to half of the snout is obliquely scored with remote 

 raised threads rising into high, sharp, arched scales. There are a few faint microscopic 

 spiral scratches. Colour a dead, faintly yellowish, semiporcellanous white. Spire high 

 and conical. Apex smooth, small, but very blunt and mamillate, consisting of little 

 more than one embryonic whorl, which is turned up on end, bent right over and spread 

 out on the. next, in which the characteristic keel appears almost immediately. Whorls 7, 

 small, of very slow increase, excessively keeled, with a hollowed shoulder above, rounded 

 and constricted below; the last is contracted very much from the middle of the base, which 

 is produced into a very long and very narrow, slightly flexuous, conical snout. Suture 

 small but distinct, and sharp, in the bottom of the wide constriction between the keels. 

 Mouth angularly rounded, running out into a small canal at the keel, and prolonged 

 below into the long, narrow, sinuous slit of the front canal. Outer lip thin, roundly 

 arched, sharply cut by the carinal canal, and again on the base by a little canal on the 

 basal thread ; it is very much pinched-in in front, and then run.s down straight along the 

 edge of the slit of the front canal. Inner lip rounded at the very top ; it then runs 

 straight to the point of the pillar ; somewhat thickened above it joins the outer lip and 

 stands out prominently from the body with a deep cleft behind it ; it is continued down 

 the whole pillar, standing out as a sharp thin lamina. .Operculum large for the aperture, 



1 So called from its likeness to Fusus pagoda, Less.
