 described by Ib'oderip, Tiiey are striped lon^ilndinally with a mixture 

 of slate color and brown, wit-li here ami thert> some jtale str(>aks: and 

 some si>ecimens have a distinct pale band around the middle of tlie 

 body-whorl; and the four apical wluuls art> bluish black. 



"This species is considerably \ariable in form, stune e\ainpl(>s Ixmu.o-

''The followiuii" measurenu'uts show how ^reat is tli«' variation in 

 leuii'th. Oiu' shell is '20 millims. lonii' ami 10 in diameter, and another 

 very short one has a lenutli of only 1(» millims.. and y«'t is the same 

 width as the louut'i' specinuai."

"'•Both tho ui>rmal form and tho varioty (/*. cohimi'llnrh) ociMirat I'harlos Ishuul." 

 Mr. Smith iiotioos tho diminntivo size of occasional adnlt examples of the latter form. 



t The anthor says '-it hears a faint relationship to T. orciillns I'hil., hut \s more 

 conoid and more strongly senlptined." .\s the numhor of examples is not stated, it 

 may he assnmed that the author had Init a single specimen as the basis of his descrip- 

 tion.
