As the type of this species I have united those specimens, which agree with such ones 

 named some years ago by Mr. E. A. Smith, though not quite agreeing in structure of the 

 upper postnuclear whorls, a few having them more squamous than the majority, which has them 

 more rounded. The deepwater specimen from Stat. 262 is an empty shell. If after all the 

 specimens prove to belong to 2 species, perhaps the plates of the projected work on Lamarck's 

 shells, will settle the question, which of both forms is the true ternispina^ they agree in pos- 

 sessing long, slender spines. E. A. Smith (Ann. and Mag. Nat. Hist. Ser. 7, Vol. XIII, p. 461, 462) 

 has made also observations on differences of sculpture "of the first three normal whorls". 



The radula of a female specimen from Stat. 5 1 has a median tooth (M) with a concave 

 anterior margin and prominent rounded angles at each side, with 3 large cusps at the posterior 

 margin, of which the lateral cusps are a little curved outwards, and much smaller intermediate 

 cusps. The laterals (i) have a broad base and terminate in a sharp point.

Differing from the type by the rufous colour of the lirae, which are stronger in accordance 

 with the strength of the corresponding spines.

The specimen from Stat. 274 is a rather young shell, a little bleached, but has the 

 coloured lirae sufficiently conspicuous, one specimen from Stat. 306 is very fine and has been 

 dredged with the soft parts, the other ones from the same locality are dead, worn shells, but 

 the dark lines may still be traced, especially in one specimen. It is somewhat uncommon that 

 the specimens from deeper water, should display the most pronounced colouring; the upper 

 postnuclear whorls are squamous.
