a COOKE : ON Jeffreys British conchology. 



entitled Phasianella '"jmlhis" or "imlla"} But I have not attempted 

 to decide what the right name of any given species actually is. For 

 instance, it has been no part of my business to substitute Pecten pes 

 lutrae for Peden septemradiahis, or Chenojms serresiamis for Aporrliais 

 viacandreae. The references have been taken as they stand. 



One or two alterations, trivial in themselves, may be mentioned 

 here, and thus save space and time. All the references to Pennant 

 are to the 8vo edition of 1777. " Miiller" is O. F. Miiller throughout. 

 When the reference to Linne is undisturbed, it means that it is (unless 

 otherwise indicated) to the 12th edition of the Systema (1766 — 68). 

 The date of the loth edition is 1758. 



VOLUME II. 



P. 14. Terebratula caput serpentis. — For ca}mt-serpentis 

 .... ed. 12, p. 1 153 read Caput serpentis .... ed. 10, p. 703, no. 200. 



P. 19. Argiope cistellula. — The reference to Searles Wood, 

 Annals, vi, p. 253, is useless, no description is there given, only a 

 catalogue. Jeffreys doubtfully referred the species to Terehratula 

 seminulum, Phil., Ann. Mag. Nat. Hist., 1847, ^'■'^! P- 3^2. The proper 

 reference for the description is Argiopte cistelhda (S. Wood), Davidson, 

 Brit. Fossil Brachiop., pt. i, p. 10 (1852), pi. i, f. 13a — d. 



P. 21. Argiope capsula. — The right reference is omitted and 

 that given is wrong. Read Argiope cistellula var. ?, Jeffreys, Ann. 

 Mag. Nat. Hist., ser. 3, 1858, ii, p. 125, pi. v, f. 4 : Terehratula capsula, 

 Jeffreys, Ann. Mag. Nat. Hist.,, ser. iii, 1859, iii, p. 43, pi. ii, f. 7a, /*. 



P. 30. Anomia ephippium. — For p. 11 50 read ed. 10, p. 701, 

 no. 185. 



I venture to suggest that the accepted derivation of the word 

 Anomia (d not, vo/xos law, hence 'lawlessness', ' irregularity'), with 

 reference to the unsymmetrical growth of the shell, is a mistake. It 

 appears to me more likely to be from di'o/xoto?, unequal; the K6y\ri 

 avojioia will then be the shell whose two valves are unequal to one 

 another. From this it will follow that we should pronounce Anomia, 

 not Anomia. 



P. 34. Anomia p.-vtellifgriniis. — For Syst. Nat., p. 1151 read 

 Fauna Suec, ed. 2 (1761), p. 521, no. 2152. This species, Aeolis 

 jmjnllosa, and Lamellidoris hilamellata are the only three British 

 moUusca, the references to whose description, according to the present 

 rules of nomenclature, are from ed. 2 of the Fauna Suecica. 



P. 38. OsTREA edulis.— For p. 1148 read ed. 10, p. 699, no. 180. 



P. 51. Pecten pusio. — For Ostrea jmsio .... p. 11 46 read 

 Ostrea Pusio . . . . ed. 10, p. 698, no. 169.
