better claim to be considered the type of E. drewi than has the shell chosen 
by Suter. Further, in the original description Hutton says there are about 
22 spirals on the body-whorl; Suter's lectotype has 12, while the smaller 
specimen — below has 18. 
Height, 13mm. ; diameter, 7 mm. 
Generically this shell iint be separated from Xymene plebeius (Hutton), 
from which it differs in the non-carination of the whorls.

Shell small, fusiform, imperforate; spire acute, equal to aperture and 
canal; whorls 6, convex, body-whorl with a high blunt shoulder, base 
contracted fairly quickly to short slightly curved neck ; protoconch broken 
in all specimens seen ; sculpture on early whorls two strong spirals with 
weaker one above, later another cord appears just above suture, body- 
whorl with 11 cords, with slightly wider flat пинен, each whorl has 
about 15 axial ribs 9 4 a variciform nature as they are traversed longitu- 
former aperture; suture well foe ssed ; aperture oval, produced below 
into short oblique recurved canal very slightly notched at end ; outer lip 
constricted suddenly to canal, varixed on outside with a sharp edge bevelled 
within and crenulate or dentic ate; columella slightly arched, meeting 
canal in prominent angle; inner lip smooth, calloused, extending half-way 
along canal.

Remarks. p amt s classification of this shell under Gould's species, 
which belongs to Tierra del Fuego, was quite tentative. both occasions 
uoted above he says that the New Zealand shell “may be distinct.” 
q 
, Evidently he was judging from figures. It is most unlikely that the shells 
should be specifically the same, considering their SUD. An exami- 
nation of Gould's description (1852) shows important differences, among 
which are “length nearly an inch . . . 8or9 ош subangular 
varices." The New Zealand shell is less than halt this length, and has 
about 15 variciform axials; it should therefore be regarded as a distinct 
species. Cossmann (1903, p. 54, footnote) changed Trophon crispus (Gould) 
to Trophon i, giving as his reason, “Cette denomination fait double 
emploi avec celle d'un Murex bien antérieur, dans l'Eocene du Bassin де 
'espéce néozélandaise doit donc recevoir un autre nom." Now, the 
shell in question was described originally (Gould, Proc. Boston Soc. Nat. 
ist., 3, р. 141, 1849) as Fusus crispus, so there is no justification for 
changing the specific name, as the Parisian shell is still retained under 
Murex. T. gouldi cannot, however, be applied to the New Zealand shell ; 
it was definitely proposed as a substitute for T. crispus, and must 
associated with that South American species.
