"Shell long-conic, of about a dozen slowly increasing whorls, which 

 are but slightly convex, but become decidedly so below, the latter two or 

 three being well rounded. Sculpture on the lower whorls of 5 rounded 

 and subequal spiral cords separated by intervals of about the same width, 

 traversed by one to three (generally two) sharp threads. Earlier whorls 

 have three primary spirals parted by intervals bearing a single strong 

 thread, and still earlier the threads disappear from the intervals." (Pilsbry) 



Remarks : This species is closely allied to the foregoing ( T. patagonicd] : 

 the external form, the suture, and the ornaments are essentially the same. 

 The only difference I can discover is found in the more rounded lower 

 whorls, which produce a more distinct suture, and in the increase of the 

 spiral ribs to 5 on the last whorl. Whether there were any granulations 

 on the principal spiral cords, is hard to say; the external casts are too 

 imperfect to render it certain, but sometimes there is the appearance of 

 granulations. 



T. cingulatif omits of Moericke (1896, p. 556, pi. 11, f. 4) from the 

 Pliocene Coquimbo beds of Chili seems to be closely allied, but it has 

 only 3 principal cords, and the suture is more depressed. 



Record of specimens : Cape Fairweather, numerous internal and exter- 

 nal casts.
