Species 6. (Mus. Cuming.) 



Bdccintjm signum. Buc. testa, ovatd, suhventricosd, mtb- 

 Pyndceformi, contortd, hasiproductdet oblique recund; 

 anfractibm tmusversim peculiariter mimitksime undu-

 nodosis, nodis promineiiiibus ; aperturd ampld ; cinered,

The rL.\G Buccinum. Shell ovate, ventricose, somewhat 

 Pyi'ula-shaped, contorted, produced and obliquely re- 

 ciured at the base ; whorls transversely peculiarly 

 very minutely striated in a waved manner, angulated 

 round the upper part, plicately uoduled on the angle, 

 nodules prominent, apertiu-e large ; ash-colour stained 

 with yellowish brown, encircled with rather distant 

 chesnut brown lines. 



Eab. ? 



A remarkable shell having somewhat the aspect of the 

 Purpura Uneata, but of quite a different form ; the general 

 character of this species, and of those which accompany it 

 in the present plate, has almost tempted me to introduce 

 them in a new imA separate genus. 



Species 7. (Mus. Cuming.) 



BucciNUM TROCHULUS. Buc. testd oblongo-ovatd, bast 

 contortd, cnnaUculatd el recurvd, spird aculd ; a/i- 

 fractibus rotimdalis, undique creberrhiie teimiUralk, 

 prope apicem nodosis ; aperturd oblongd, fauce irregu- 

 lariter el inlerrupte liratd; Inleospadiced, lineis albis 

 distantibvs cingulatd. 



The little top Buccinum. Shell oblong-ovate, twisted, 

 channelled and recurved at the base, spii'e shaqi ; 

 whorls rounded, very closely finely ridged tlu'ough- 

 out, nodided near the apex ; apertm-e oblong, interior 

 iiTegularly and interi-uptedly ridged ; yellowish bay 

 colom-, encii-cled with distant white lines. 



Bab. ? 



Another characteristic species of rarity which does not 

 appear to have been hitherto recorded. 



Species 8. (Mus. Brit.) 



Buccinum impeeiale. Buc. testd ovatd, tenuiculd, 

 injlatd; anfractibm transversim strialis et obscure 



liratis, supeme cowcavo-angnlatis, ad anguUim obtuse 



carinatis ; aperturd perampld ; sordidi albidd, auran- 

 tio-fusco, prtEcipue ad anguliim, muculald et punctata. 



The imperial Buccinum. Shell ovate, rather thin, 

 inflated ; whorls transversely striated and obsurely 

 ridged, couoavely angulated round the upper part, 

 obtusely keeled at the angle ; apertm-e very large ; 

 dull white, blotched and dotted, especially at the 

 angle, with orange-brown. 



Eab. ? 



A species of very peculiar form and coloming, unique, 



as far as I can ascertain, in our national collection. 



Species 9. (Mus. Cmning.) 



Buccinum FusoiDEs. Buc. testd fiisiformi, basi canali- 

 culatd et recurvd, transversim undique liratis, liris 

 angustis, conferfiusculis, interstitiis longiludinaliter 

 strialis ; aperturd oblongd, fauce liratd ; fuscescerde, 

 liris maculis pai'vis saturatioribus profuse tinctis. 



The Fusus-like Buccinum. Shell fusiform, channelled 

 and recm-ved at the base, transversely ridged through- 

 out, ridges narrow, rather close-set, interstices longi- 

 tiulinally striated ; aperture oblong, interior ridged ; 

 light brown, ridges profusely stained with small spots 

 of a deeper coloiu'. 



Eab. ? 



If it were not that this species falls into the present 

 series, distinguished by the recurvature of the channelled 

 base, it might be referred with propriety to the genus 

 Fusus. 



Species 10. (Mus. Cuming.) 



Buccinum varicosum. Buc. testd subfusiformi-turritd, 

 basi canaliculatd el recurvd, spira suturis snbimpressis, 

 avfractibus subrolundis, tramversim couspicue elevato- 

 striatis, longiludinaliter costalis, costis obtusis, subdis- 

 tantibus ; aperturd parvd ; sordide fuscescente. 



The varicose Buccinum. Shell somewhat fusiformly 

 tm-reted, channelled and recmwed at the base, 

 sutm-es of the spire rather impressed ; whorls nearly 

 roimd, transversely conspieuously elevately striated, 

 longitudinally ribbed, ribs obtuse, rather distant ; 

 aperture small ; dull brown.
