ON MOLLUSCA OF THE WEST COAST OF NORTH AMERICA. 547 
agrees with Pyramidella, sp. ind., C. B. Ad., no. 293 (not 294), and may be 
quoted as Obeliscus Adamsii. 
487, 488, Belong to Evalea, A. Ad. 
489. 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 probably belongs 
to Diala, A. Ad., and= Cingula paupercula, C. B. Ad., no. 253. 
498-500. Belong to Miralda, A. Ad. Parthenia quinquecincta=? Cingula turrita, 
C. B. Ad.,+ Rissoa notabilis, C. B. Ad. 
501, 502. Belong to Oscilla, A. Ad. Parthenia exarata=? Oingula terebellum, C. B. Ad. 
505-506, The “ Odostomoid Chrysallide” probably rank best with Mwmiola, A. Ad. 
512. Chrysallida ovulum=? Cingula inconspicua, C. B. Ad. ; non ? Rissoa inconspicua, 
C. B. Ad. nec Alder. 
513-515. Are Pyrgulina, teste A, Ad. The Japanese species, however, seem more 
like Parthenia, no. 497. 
517. Is a Styloptygma, A. Ad. 
520. This is not the Chemmitzia similis of C. B. Ad.; and is probably a variety of 
Ch. Panamensis. 
523. = Chemnitzia affinis, C. B. Ad., pars: pars= Ch. undata, no. 531. 
535. Is perhaps a Mormula, A. Ad. 
545. 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 Lulimeila. 
550. This is not Lezostraca recta, C. B, Ad., and may be called Mucronalia involuta, 
551. This is not L. solitaria, C. B. Ad., and may be called Z. producta. 
552. = Mucronalia solitaria, C. B. Ad. 
553. Ranks best with Hulima, teste A. Ad. 
555. L.retera; distinct from LZ. cota, C. B. Ad. 
556. Should be Eulima, teste A. Ad. 
557. Vide note to 393. 
563. Belongs to the subgenus Sela, A. Ad. 
568. Scalaria raricosta is perhaps the young of S. Elenensis. 
569. S. funiculata and S. diadema, with their congeners, should be removed from 
Cirsotrema to Opalia. 
570. 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. Itis 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 Phastanelle, to which the name 
Eucosmia may be given. 
580. Appears under genus “ Lagena, Wein,’ * in Mus. Cuming; the Argobuccina 
cancellatum, Oregonense, &c., haying 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 ‘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, Mérch, 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-lunaris, 
Cochlea-celata, &e.; Buccinum-lacerum, Buccinum-muricatum, Thema-musicum, &e.; 
Ostrewm-imbricatwm, Ostrewn-muricatum, &e.; Musculus-latus, Musculus-mammarius, 
&e.; Tellina-arcinata, Tellina-virgata, &c.; Concha-longa-biforis, Concha-longa-uniforis; 
Concha-rpidoBos;” and, in p. 167, “* Museculus-polylepto-ginglymus,’ under which re- 
markable generic name is given as the first species “‘ Arca-Noe.” According to the now 
fashionable transformation of malacological nomenclature into a branch of archeological 
research, under pretence of justice to ancient writers, the hitherto universally understood
