Vol. iii. p. 53. LiTTORiNA palliata. 



The remark, that the L. pctUiata must, probably, be included 

 in L. littoralis, is not to be understood as referring to the verit- 

 able N. American species, but solely to the British specimens 

 usually identified with it. The L. fahalis seems intermediate in 

 character between the two ; it differs from the former in the 

 breadth and concavity of the surface of the pillar lip ; from the 

 latter (littondis), in the roundness of its volutions, and the eleva- 

 tion of the spire in the more mature individuals. Our figures, 

 drawn from immature examples, are not characteristic, the aper- 

 ture of the adult not being so angular below, but well rounded 

 and diminished in expansion by the breadth of the liver-coloured 

 pillar lip. The specimens now before us measure a quarter of an 

 inch wide, and do not exhibit any nearer approach to littoralis 

 than those before described ; yet the aggregate of differences be- 

 tween the two is not comparable to that which exists between the 

 typical rudis and its variety tenebrosa. 



Vol, iii. p. 62. Lacuna vincta. 



We are disposed to refer to this species the Turbo cmricidaris 

 of Montagu (Test. Brit. vol. ii. p. 308, from which, Maton and 

 Back. Trans. Lin. vol. viii. p. IGG; Turt. Conch. Diction, p. 

 206 ; Dillw. Recent Shells, vol. ii. p. 844 ; Flem. Encycl. Edin. 

 vol. vii. pt. 2, pi. 205, f. 6 ; Cingida aiiricularis, Flem. Brit. 

 Anim. p. 307). 



Vol. iii. p. 72. RissoA. 



In the "Annals of Natural History" for October, 1852, our 

 friend, Mr. Clark, remarks upon the Rissoce, that cosddata, ru- 

 Jilabris, and possibly labiosa, are varieties of parva, that ptd- 

 cherrima is a dwarf nearly ribless inconspicua, and littor'ea 

 apocryphal as British. With every respect for his talents as a 

 malacologist, we are compelled very frequently to dissent from 

 his conclusions as a conchologist.
