i OX MOLLUSCA OF THE WEST COAST OF NORTH AMERICA, 5 i7 



ngrees with Pi/rami'della, sp. ind., C. B. Ad., no. 293 (not 294), and may b* 



quoted as Obeliscus AdamsiL 

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

 489. Is a Syrnola, A. Ad. 

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



discovery of an adolescent and several adult specimens. It -probably belongs 



to Dinla, A. Ad., and= Cingula paupercula, C. B. Ad., no. 253. 

 498-500. Belong to Miralda, A. Ad. Parthenia quinquecinda = ? Cingula turrit n f 



C. B. Ad.,4.jR&sa0 notabilis, C. B. Ad. 



501, 502. Belong to Oscilla, A. Ad. Parthenia exarata^? Cingula terebeUum,C.ft.A<l. 

 503-506. The " Odostomoid C/irysallidee " probably rank best with Mumiola, A. Ad. 

 512. GhrysaMida ovulum=? Cingula inconspicua, C. B. Ad. ; non ?Rissoa inconspicua, 



C. B. Ad. nee Alder. 

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



like Parthenia, no. 497. 

 517. Is a Stylopti/gma, A. Ad. 

 520. This is not the Chemnitzia similis of C. B. Ad. j and is probably a variety of 



Ch. Panamensis. 



523. = Chemnitzia qffinis, C. B. Ad., pars : pars= Ch. ttndata, no. 53]. 

 535. Is perhaps a Mormula, A. Ad. 

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



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



549. Ranks best with Eulimella. 



550. This is not Leiostraca recta, C. B. Ad., and may be called Mucronalia involute. 



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



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



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



555. L.retexa-, distinct from L. iota, C. B. Ad. 



556. Should be Eidima, teste A. Ad. 



557. Vide note to 393. 



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



568. Scalaria raricosta is perhaps the young of 8. JElenensis. 



569. S. funiculata and 8. 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 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- 

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

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



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

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

 Eucosmia may be given. 



580. Appears under genus " Lagena, Klein,"* in Mils. Cuming; the Argobuccina 

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



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



* The names of Klein in his 'Tentaraen' 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-phonurgica, Cochlea-lunar -w, 

 Cochlea-ccelata, &c. ; jBuccinum-lacerum, Buccinum-murivatum, Thema-musicum, &c. ; 

 Ostreum-imbricatum, Ostreum-muricatum, &c. ; Musculus-latus, Mwculus-mammarius, 

 &c. ; Tellina-arcinata, Tellina-virgata, &c.; Concha-long a-Hjoris, Coneha-longa-uniforis; 

 Concha-rpiXofios ; " and, in p. 167, " Musculus-polylepto-gingtymus" under which re- 

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

 fashionable transformation of malar-ological nomenclature into a branch of archaeological 

 research, under pretence of justice to ancient writers, the hithevto unirersully understood
