T. LIRATUS. Couthouy. PL 31, tig. 333. 



Animal and shell pale yellow ; operculnm fusoid. Shell fusi- 

 form, polished, with traces of a thin epidermis ; the whorls are 

 crossed by about twenty close-set, angular ridges, and the inter- 

 stices have deep-cut revolving stria?. Aperture white, clouded 

 with purple ; columella with a purplish callus ; lip simple, but 

 bordered with the last angular ridge. Length, '75 inch. 



Dredged at Orange Harbor (Terra del Fuego), 15 fathoms, Couthouy. 

 Castle Point, Manchuria, Japan, 20 fathoms, A. Adams. 



It is not probable that both these localities are correct. The 

 external appearance of the shell is somewhat like a Urosalpinx. 



T. CRISPUS, Gould. PL 31, figs. 321. 323, 328, 329; PL 70, 

 fig. 437. 



Animal yellow. Shell ashy, polished and purplish within; 

 lip evasive, deeply furrowed within. Length, 1 inch. 



Dredged at Orange Harbor, 16 fathoms. 



Arthur Adams quotes this species also from Japan probably 

 an error in identification. Animal very timid ; when fully pro 

 truded, the head is not advanced beyond the foot. A scalariform 

 monstrosity occurs. 



Murexpallidus^i'od. (fig. 329), from Falkland Islands, appears 

 to be the young of this species; Fusu-sfasciculatu*, Hombr. (fig 

 328), and F. fitnbriatm?, Gay (PL 70, fig. 437), are also the same 

 species. 



T. LACINIATUS, Martyn. PL 31, figs. 330-332. 



Shell whitish, chestnut within the aperture; animal yellow. 



Length, T5-2 inches. 



Magellan's Sts., Falkland Isles. 



1 do not hesitate to unite with this species T. antarctic us, Phil. 

 The single specimen on which the description is based is said to 

 be narrower, the lamellar spines on the shoulder shorter, etc. I 

 have before me specimens which answer well to this description, 

 as well as intermediate forms.
