A small species, but distinguished, as the specific name chosen would show, by 

 its very attenuate, fusiform whorls, the last three or four swollen, caudate, shining, 

 smoothly costulate, not spirally crossed with granose line, as are the lower whorls ; the 

 columella is only slightly rostrate, the outer lip thin, the colour whitish straw. But 

 few examples occurred, (fid/epos oupa, long-tailed.)

As mentioned in our first paper, we issued a description of this species in 1907, 

 using, at Dr H. STREBEL'S request, the name he had given it in manuscript. The 

 following year it was redescribed by him as " sp. nov.," and we are of opinion that he 

 had not at that time seen our paper. The same remarks would apply also to Trophon 

 minutus, M. and S.

 and the body whorl, between the strong median keel and the base, possessing three such 

 spiral liratious.
