ngrees with Pyramidella, sp. ind., C. B. Ad., no. 293 (not 294), and mav be 



quoted as Obeliscus Adumsii. 

 487, 488. Belong- to Evalea, A. Ad. 

 Af^Q. Is a Syrnola, A. Ad. 

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



discovery of an adolescent and several adult specimens. It rroljably belongs 



to Diala, A. xVd., miA^ Cingula paupercula, C. B. Ad., no. 2-53. 

 408-500. Belong to Miralda, A. Ad. Parthenia quinquecincta=? Cingula turriUt, 



C. B. Ad., +i?issoa notabilis, C. B. Ad. 

 501, .502. BelongtoOsejV/fj, A. Ad. Parthenia exarata=^Cingulaterehellum,C'R.AA. 

 503-506. The "Odostomoid C/jn/sa&'rf(E"probably rankbest with J/timiWa, A. Ad. 

 512. Chrysallida omdmn=^? Cingula inconspicua, C. B. Ad. ; non ?Itissoa inconspicua, 



C. B. Ad. nee Alder. 

 513-515. Are Pyrgidina, teste A. Ad. The Japanese species, however, seem more 



like Parthenia, no. 497. 

 517. Is a Styloptygma, A. Ad. 

 520. This is not the Chemnitzia similis of 0. B. Ad. ; and is probably a variety of 



Ch. Panamensis. 

 523. = Chemnitzia affinis, C. B. Ad., pars : pars= C%. undata, no. 531. 

 535. Is perhaps a Mormula, A. Ad. 

 545. The various shells grouped under ylcZis require revision. Comp. 0»o5b, A.Ad., 



and Ebola, Gray, which is figured as Aclis in Add. Gen. 



549. Ranks best with EulimeUa. 



550. This is not Leiostraca recta, 0. B. Ad., and may be called MucronaMa invohda. 



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



552. =Miicronalia solitaria, 0. B. Ad. 



553. Ranks best with EuUma, teste A. Ad. 



555. L. retexa ; distinct from L. iota, 0. B. Ad, 



556. 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. funieulata 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 gTOund that "he can separate the African from the Pacific shells as fast 

 as we can hand them to him." So easily can any ordinary naturalist separate 

 conspecific British and Mediterranean specimens, or Mazatlan and Panama 

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

 forniea " being the ordinary t3^e from the Pacific Islands, which is much 

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



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

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

 Eucosmia may be given. 



580. Appears under genus " Lagena, Klein," * in Mus. Cuming ; the Argohuccinu 

 cancellatum, Oregonense, &c., having received a new name, Priene, H. & A. Ad. 



689. This belongs to Closia, Gray, = Voluiella, Swains., non D'Orb. 



* The names of Klein in his 'Tentamen' and ' Luoubratiunoula,' 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, Morob, or other writer who 

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

 Stella, &e. ; Auris, Anas, Tigris, Fes-anserinus, Taha-phonurgica, Cochlea-lunoA'ls, 

 Cochlea-ccelata, &c. ; JBuceinum-lacermn, Bueeinum-mitHcatum, Thema-mwsieum, &c. ;. 

 Ostreum-imiricatmn, Ostreum-muricatnm, &e. ; Musculus-latus, Musculus-mamma/rius,. 

 &c. ; Tellina-arcinafa, Tellina-virgata, &o.; Concha-longa-liforis, Concha-longa-uniforis;. 

 Co»cAa-rpiXo/3os ; " and, in p. 167, " Museulus-polylepto-ginglymus," under which re- 

 markable generic name is given as the first species " Arca-Noce." According to the now 

 fashionable transformation of malacological nomenclature into a branch of archseological 

 research, under pretence of justice to ancient writers, the hitherto unirersally understood
