314 APPENDIX. 



Fusu3 FoRBESi. Strickland. 



" According to ^Ir. G. B. Sowerby, identical with Fimis cinereus, Say, an American species, synonymous 

 with Jiuccinum jilicosumoi "Slcnke." — Forbes, 'Mem. Gcol. Surv.,' vol. i, p. *12C. 

 LocaUty. Isle of Man. 



"Fusus Bakvicensis. Johnston. 



"Locality. Fossil, Irish Drift. 



Living, Northern Coasts of Britain." 



"Fusus Bamffius. Donovan. 



"Locality. Fossil, one of the most generally difl'used and abundant species in the British and Irish 

 Glacial Beds. 

 Living, Northern and Arctic Regions of the European Seas, common on the Scottish 

 Coasts, Greenland, Seas of Boreal America." — Forbes, ' Jlem. Geol. Surv.,' vol. i, p. 425.

p. 15G, No. 20. 



" F. Testd oblongd, crassinsculd, Icevigatd, spiraliter striatd ; un/ractibus subrotundatis quinque, ultimo 

 majori ; aperlurd oblongd, magnd ; canali brevissimo obtuso. Long. 0'3, lat. 0'12, poll." 



"This species has the form of many Pleurolomata, particularly of PL fdosa, 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 Fusi ; 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 Jlr. 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 PI. reticulata. Brown. PI. Trevelliunum, 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 prouiineut 

 ribs, which are traversed by raised spiral ridges. The characters are those of F. crispus, 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. 



"Locality. Fossil, Wexford.* 



Living, F. crispus is at present a Jlediterrancan species. 



"It occurs fossil in the Sub-Apenninc beds." — Forbes, '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. 

 Mioc. de I'ltal. Septen.,' p. 272, No. 3, pi. 9, figs. I", 18, who refers to Borson, ' Oritt. Piemont,' p. 31". 



It is not mentioned by I'rocchi. 



* Every possible assisiance lias been most obliguiijly n-ndcred 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.
