The identification of this species is difficult. Authors don't agree about its specific value. 

 Tryon cites as synonyms: disjunctus Anton, concinnus Phil., articulatus Reeve, elegans Phil., 

 radiatus Reeve, v. Martens wrote me, that 7\ Winteri Phil, is identical. The largest specimen 

 from Stat. 193, has squamous lirae, that from Makassar, though collected alive, is much worn 

 and remains uncertain. The other specimens are mere shells.

It is often very difficult, to separate the species of the subgenus Senectus^ after shell 

 characters ; the specimens mentioned above are not umbilicate, and only show in some specimens 

 a very small umbilical slit, which character seems to distinguish this species from T. concimms 

 Phil, and intercostalis Mke. After having examined the radula of a rather doubtful specimen,
