Magn. long. 30 lat. 18"”, apert. long. 15 diam. max. 
6mm, 
Forekomst: St. 124—350 F., St. 326—123 F. 
Dyret (Fig. 23) er hvidt, kun Sipho og Tentaklerne 
blaagraa. Foden har omtrent Skallens Længde, fortil 
truncat, bagtil bredt afrundet, Sipho middelmaadig lang, 
Tentaklerne lange og spidse og Øjnene sidde noget frem 
paa disse paa en svag Forhøining. 
Apex (Fig. 24 a, ) ligner nærmest N. gracilis. 
Operculum (Fig. 25) er stort, lukker for Mundaab- 
ningen, piriform og noget bøiet for nedre Ende. 
Denne Art staar Sipho Verkriizeni, Kobelt (Jahrb. 
Mal. Gesell. 1876 Pg. 70 Taf. 2 Fig. 1) nær, men foruden 
at Spiret hos den sidste er betydelig længere, saa er og- 
saa Sculpturen og Operculum væsentlig afvigende. 
Mr. Robert Bell i London har havt den Godhed at 
sende mig en Crag Fossil under Navn Fusus altus S. Wood, 
der ligner vor Art i den Grad, at Fig. 22 næsten er et 
correct Billede deraf. Der findes den samme fine Spiral- 
striering, de ejendommelige Længdefolde og den korte Canal 
(Apex er desværre brudt), kun er Vindingerne noget mere 
tumide. S. Woods Beskrivelse af Trophon altum (Crag. 
Moll. I Pg. 47) passer godt paa “volutions convex” nær, 
baade paa Mr. Bells Fossil og vor recente Form, men 
derimod ligner hans Tegninger (1. ce. T. VI Fig. 13 a, 5 
og endnu mindre Supp. T. II Fig. 17 a, b) meget lidet. 
Dersom Mr. Bells Cragfossil virkelig er S. Woods 
Trophon altum, hvad jeg ikke tør have nogen afgjørende 
Mening om, da jeg ikke kjender Woods Typeexemplarer, 
tvivler jeg ikke paa, at det af mig givne Navn virgata 
kommer at vige Plads for Woods. 
Tenderne (Tab. V, Fig. 3—4) synes ikke i nogen særlig 
Grad at adskille sig fra N. islandica. Hos det ene Exemplar 
(Fig. 4) var der paa Centralpladen snart? snart 3 Tænder. 
Rækkernes Antal er omkring 70.

Magn. long. 50°", lat. 137". apert. long. 157” diam. 
max. 6", 
Habitat: — Stats. 124 (350 fathoms) and 326 (123 f.). 
The animal (fig. 23) is white, the siphon and tentacles 
only being of a blue-grey tint. Foot about equal in length 
to shell, anterior extremity truncate, posterior extremity 
broadly rounded; siphon of moderate length, tentacles long 
and acuminate, with the eyes some distance out on aslight 
prominence. 
The apex (fig. 24 a, ») has most resemblance to N. gracilis. 
Operculum (fig. 25) large, closing the aperture, pyri- 
form, and slightly bent at the lower extremity. 
This’ species is nearly allied to Sipho Verkriizeni, 
Kobelt (Jahrb. Mal. Gesell. 1876, p. 70, Pl. 2, fig. 1); but 
the spire in the latter is considerably longer, and the sculp- 
ture and the operculum exhibit essential deviations. 
Mr. Robert Bell of London has had the kindness to 
send me a crag-fossil, named Fusus altus, S. Wood, so 
closely resembling virgata, that fig. 22 might almost serve 
as an accurate representation of both. The delicate stria- 
ture, the peculiar longitudinal folds, and the short canal 
(the apex is unfortunately broken) are no less characteristic 
of the fossil than of the recent shell; the only difference 
lies in the whorls of the former being a trifle more tumes- 
cent. S. Wood's description of Trophon altum (Crag. Moll. 
I, p. 47) agrees closely, save in “volutions convex,” alike 
with the characters of Mr. Bell’s fossil and those of our 
recent form; his drawings. ou the other hand (1. c., Pl. VI, 
fig. 13 a, b, and more especially in Supp. PI. II, fig. 17 
a, b), present very little resemblance to either. 
Should Mr. Bells erag-fossil really prove to be S. 
Woods Trophon altum, on the probability of which I cannot 
venture to pronounce, having never seen Wood's type- 
specimen, the name of virgata, which I have given to the 
form, will doubtless be dropped, and that given by Wood 
retained in preference. 
The dentition (Pl. VI, figs. 3, 4 would not appear to 
differ essentially from that im N. islandica. In one Radula 
(fig. 4), the central plate had now 2, now 3 cusps. 
Number of series about 70.
