THE VOYAGE OF H.M.S. CHALLENGER. 



highest and broadest lies close to the suture, is flat, and is made up of about four threads 

 parted by minute superficial furrows ; the second baud lies above the middle of the whorl, 

 is made up of about two threads, parted by a distinct furrow, and is separated from the 

 first band by a strongish depression in which lie two minute threads ; the furrow below 

 this second band is deeper and squarer than the first, and has one distinct thread in the 

 bottom of it ; the lowest band is more or less distinctly double, and has a distinct sutural 

 constriction below it ; on the base are many small rounded threads, of which those round 

 the pillar are feeble. Colour : the upper part of each whorl is whitish chestnut, the lower 

 ruddy chestnut ; the base and apex are pale. Spire long and narrow, bent near the top. 

 Apex unusually large and mamillate ; the extreme tip is flattened down on one side ; the 

 first whorl-and-half is smooth, the next half-whorl longitudinally barred. Whorls 17 to 

 18, rather short, and of regular increase. Mouth small (much broken). Pillar short, 

 much twisted, and with an anterior double fold. H. 1"35 in. B. 0"25. 



There is no species with which this can be very well compared. (Terebra bathyraphe, E. A. Sm., 

 has some resemblance, but in all details is different.) The coarse, abrupt, smooth, round apex 

 distinguishes it from all others. Tercbra jcffreysi, E. A. Sm., and Terebra torquata, A. Ad., have both 

 a large blunt apex, but the former has the very tip smaller and the next whorls larger — this besides 

 being in a general way a smaller narrower species of different sculpture ; the latter is very like 

 (though not identical) in sculpture, the apex is smaller and the spire finer.
