r2:rees witli Pi/nintidclla, sp. iud., C. B. Ad., no. 293 (not 294J, and may bs 



quoted as ObeU'^cits Adamsii. 

 4S7, 488. Belong to Evcdca, A. Ad. 

 4'- 9. Is a Si/rnola, A. Ad. 

 492. The jjeculiar appearance of the apex is due to decollation, as proved by the 



discovery of an adolescent and several adult specimens. It ] roljably belongs 



to Di(da, A. Ad., (inA= Ciiifjida ^JfU'pcrcida, C. B. Ad., no. 2-'33. 

 498-500. Belong to Miralda, A. Ad. Parfhenia quinquecinctu^':^ Ciiu/ula turn'tn, 



C. B. Ad., + Ms-wa notahUis, C. B. Ad. 

 501, .502. Belong to OscUla, A. Ad. Parthoiia e.rarafa:=? Cingida tercheUinn, C. B. Ad. 

 50.3 -50G. The " Odostomoid Chn/sallido! " probably rank best with Mnmiola, A. Ad. 

 512. Clirysallida oi-idum = ? Cinyula mconsjiicua, C. B. Ad. ; non YHissoa incon^picua, 



C. B. Ad. nee Alder. 

 513-515. Are Pi/rgidina, teste A. Ad. The Japanese species, however, seem more 



like Parthenia, no. 497. 

 517. Is a StyIopfi/(/ma, A. Ad. 

 520. This is not the Chenmitzia similis of C. B. Ad, ; and is probably a variety of 



Ch. Paiiatnensis. 

 523. = Chemiiitzia affims, C. B. Ad., pars : pars= Ch. undata, no. 531. 

 5!5. Is perhaps a 3Iurmida, A. Ad. 

 645. The various shells grouped under Aclis require revision. Comp. Onoba, A. Ad., 



and Ebala, Gray, which is tigured as Aclis in Add. Gen. 



549. Banks best with EuUmella. 



550. This is not Leiostrnca recta, C. B. Ad., and may be called 3Iuc nnaUa involntci, 



551. This is not L. solitaria, C. B. Ad., and may be called L. producta. 



552. = Miicronalia solitaria, C. B. Ad. 

 5-'>3. Ifanks best with Eidima, teste A. Ad. 

 555. L. retexn ; distinct from L. iota, C. B. Ad. 

 S.-jG. Should be Eidima, teste A. Ad. 



557. Vide note to 393. 



563. Belongs to the subgenus Seila, A. Ad. 



568. Scalaria raricosta is perhaps the young of S. Elenensis. 



569. S. fimiculata and S. diadema, with their congeners, should be removed from 



Cirsotrema to Opalia. 



670. Dr. Gould dissents from the affiliation of this shell to the West African species 

 on the ground that "he can separate the African from the Pacific shells as fast 

 as we can hand them to him." So easily can anj' ordinary naliu-al'sfc separate 

 conspecitic British and Mediten-anean specimens, or Mazatlan and Panama 

 specimens. It is not found in the West Temperate fauna ; the " var. Cali- 

 fornica " being the ordinary type from the Pacific Islands, which is much 

 more entitled to be regarded as distinct than are the'West Amencan forms. 



572. Is shown by perfect Cape St. Lucas specimens to belong to a natural group 

 of species, resembling flattened, perforated Phasianellce, to which the name 

 Eucosmia may be given. 



580. Appears under genus '■'■ Lagena, Klein,"* in Mus. Cuming; the Argobiiccina 

 canccllatum, Oreyonense, &c., having received a new name, Priene, H. & A. Ad. 



589. This belongs to Closia, Gray, = Vohdella, Swains., non D'Orb. 



* The names of Klein in his 'Tentamen' and ' Lucubratiuncula,' 1773, are not entitled 

 to precedence (according to the Brit. Assoc, rules), because he evidently did not adopt the 

 Linnean mode of binomial nomenclature. What he calls a " genus " answers more to the 

 modern idea of chapter or section. By chance, some of his names are allowable; but, if 

 used, the genus must be regarded as that of Adams, Gray, Morch, or other writer who 

 defines it. The following will serve as illustrations of Klein's "genera" — "Sol, Luna, 

 Stella, &c. ; Auris, Anas, Tigris, Pes-anserinus, Tuba-phoniirgica, Cochlea-lunarl^ , 

 Cochlea-calata, &c. ; Buccinum-lacerum, Buccinum-muricatum, Thema-miisicvm, &c. ; 

 Ostreum-imhricatum, Ostreum-mtiricatum, &c. ; Muscidiis-latus, Musculus-mammarius, 

 &.C.; Tellina-arcinata, Telluia-virgata, &c. ; Concha-longa-hiforis, Concha-long a-unif oris; 

 Cow(v'i«-rp(Xo/3os; " and, in p. 167, " Musculus-polglepto-ginglymus," under which re- 

 rwivVxhXi^ generic name is given as the first species " Arca-Noee." According to the now 

 fashionable transformation of malacological nomenclature into a branch of archseoiogical 

 research, under preteuce of justice to ancient writers, the hitlic^lo luii^ fr.i:illy uuderslood
