Forekomst: St. 124—350 F.. St. 326—123 F. 



Dyret (Fig. 23 1 er hvidt. kim Sipho og Teutaklerne 

 blaagraa. Foden har omtrent Skallens Længde. fortil 

 truncat. bagtil bredt afrundet. Sipho middelmaadig lang, 

 Teutaklerne lange og spidse og Øjnene sidde noget frem 

 paa disse paa en svag Forhøming. 



Apex (Tig. 24 a. b) ligner nærmest N. gracilis. 



Operculum (Fig. 2n) er stort, lukker for Mundaab- 

 ningeu. piriform og noget bøiet for nedre Ende. 



Denne Art staar Sipho Yerkruzeni, Kobelt (Jahrb. 

 Mal. Gesell. 1876 Pg. 70 Taf. 2 Fig. 1) nær. men foruden 

 at Spiret hos den sidste er betydelig hengere, 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 alius S. Wood, 

 der ligner vor Art i den Grad. at Fig. 22 næsten er et 

 correct Billede deraf. Der tindes den samme fine Spiral- 

 sti'ieriug. 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. c. T. VI Fig. 13 a, b 

 og endnu mindre Supp. T. II Fig. 17 a. 6) meget lidet. 



Dersom Mr. Bells Cragfossil virkelig er S. Woods 

 Trophon altum, hvad jeg ikke tor 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. 



Tænderne .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 2 snart 3 Tænder. 



Rækkernes Antal er omkring 70.

Magn. long. 30"' m . lat. 13 mm . apert. long. lo mm diam. 

 max. 6 mm . 



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 a slight 

 prominence. 



The apex (fig. 24 «. ><< has most resemblance to K. gracilis. 



Opercxdum (fig. 2.">) large, closing the aperture, piri- 

 form, and slightly bent at the lower extremity. 



This species is nearly allied to Sipho Yerlriizeni. 

 Kobelt (Jahrb. Mal. Gesell. 1876. p. 70, PI. 2. fig. L); 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 altas. 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 cannl 

 (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, on 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 Mi - . Bell's crag-fossil really prove to be S. 

 Wood's 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 (Pi. VI, figs. ;;. 4i would not appear to 

 differ essentially from that in N. islandica. In one Radula 

 (fig. 4). the central plate had now 2. now 3 cusps. 



Is umber of series about 70.
