314 APPENDIX. 
Fusus Forsgst. Strickland. ¥ 
“ According to Mr. G. B. Sowerby, identical with Fusus cinereus, Say, an American species, synonymous 
with Buccinum plicosum of Menke.” —Forbes, ‘Mem. Geol. Surv.,’ vol. i, p. 426. 
Locality. Isle of Man. 
«Fusus Barvicensis. Johnston. 
“ Locality. Fossil, Irish Drift. 
Living, Northern Coasts of Britain.” 
‘«“Pusus Bamrrius. Donovan. 
“Locality. Fossil, one of the most generally diffused and abundant species in the British and Irish 
Glacial Beds. 
Living, Northern and Arctie Regions of the European Seas, common on the Scottish 
Coasts, Greenland, Seas of Boreal America.”—Vordes, ‘Mem. Geol. Surv.,’ vol. i, p. 425. 
«“Fusus curtus. Smith. MS. Tert. Dep. of the Basin of the Clyde, Trans. Geol. Soc., 2d ser., vol. vi, 
p. 156, No. 26. 
“F. Testd oblongd, crassiusculd, levigatd, spiraliter striata ; unfractibus subrotundatis quinque, ultimo 
majori ; aperturd oblongd, magnd ; canali brevissimo obtuso. Long. 0°3, lat. 0°12, poll.” 
“This species has the form of many Pleurotomata, particularly of Pl. filosa, but it has not the notch 
near the posterior part of the outer lip which characterises that genus. I have, therefore, found it necessary 
to place it with the Fwsi ; the very short, scarcely evident canal, however, tends to separate it from the more 
typical species of Fusus.” 
The above description of the Clyde Beds fossil has been obligingly forwarded to me by Mr. Smith, of 
Jordan Hill; it was drawn up by the late Mr. G. B. Sowerby. From what I can learn of this shell, which 
I have not been able to see, it probably belonged to Pl. reticulata, Brown. Pl. Trevellianum, Turt. 
Mangelia Trevelliana, Forbes and Hanley. 
‘“« Fusus nov. sp.? or variety of F. crispus, Brocchi (*). 
«A shell measuring above an inch in length, fusiform, the whorls narrow, and crossed by prominent 
ribs, which are traversed by raised spiral ridges. The characters are those of F’. erispus, of which it is 
probable an extreme form; but more perfect specimens are required for accurate determination. It is very 
distinct from any recorded Drift fossil. 
“Tocality. Fossil, Wexford.* 
Living, F. crispus is at present a Mediterranean species. 
“Tt oceurs fossil in the Sub-Apennine beds.”—Forées, ‘Mem. Geol. Surv.,’ vol. i, p. 426. 
There is a specimen from the Red Crag in my cabinet, which resembles this species; but it is in a 
worn and mutilated condition, and undeterminable. /F. crispus is figured by Michalotti, ‘ Desc. des Terr. 
Mioe. de I’Ital. Septen.,’ p. 272, No. 3, pl. 9, figs. 17, 18, who refers to Borson, ‘Oritt. Piemont,’ p. 317. 
It is not mentioned by Brocchi. 
* Every possible assistance has been most obligingly rendered to me by the officers of the Geological 
Survey, in their endeavours to discover this and some other Fossils, but all their exertions have been 
unsuccessful. Not anticipating the calamity that has deprived us of our lamented associate and friend, 
the late Professor E. Forbes, I did not think it necessary to apply to him respecting these species until I 
began to work upon the Appendix, knowing his ever-ready willingness to assist whenever occasion might 
require. My application has been thus unfortunately delayed, which I should the more regret were it not 
that his authority for the existence and correct determination of these species is quite sufficient without any 
endorsement I could give them.
