28. Auida f(dc(dn. [The locality of ^Ir. Cuming's specimens ha.s nut been con- 

 firmed. For " .species," in note, read " spfcinien-i.'' j 



31. Lhna tetrica. [The specimens from the Mediterranean, VV. Indies, Gulf Cal., 

 and Pacific Islands were all named L. squamosa by Mr. Cuming.] 



3-3. Balimus vcsicalis ( nom. prcoc. ) = 5. siiffltdiis, ' Otia,' p. 184. 



40. Xdci'da pideacva. [Col. Jewett'.s specinifn.s appear distinct from X. dvpicta,\\A^.'\ 



41. Tioc/iiis murcidus. [Thi.s shell was called Omphaliux I'fiiffcri by Mr. Ciiminy, 



from the resemblance of the figure, in which the umlnliciis appears keeled ; 

 but the shell marked ' type,' answering to the diagnosis, along with ' Chloro- 

 stoma' niaculoston, A. Ad., are scarcely varieties of Phorcus pulliyo, Martyn. 

 The finest series is in the li. M.] 



43. Lirnna picoidea [has been heard of, but not seen since the explorations of Col. J. 

 Dr. (tUL still considers the species distinct : among the very div^imilar varieties 

 from the W. Indies (vide suite in B. M.) it woidd probably not have beea 

 singled out as a species, but for the theory of the author]. 



45. Cmcihulum Jeiccttii [should be rdrrtupitum, P. Z. !S.]. 



47. Modulus dorsiiosus. [Col. J. now thinks that the supposed Acapulco specimens 

 are W. Indian, =/t'«<(Vj//am, Cheni. When dead, the forms from the two 

 oceans can hardly be distinguished ; but the aspect of his shells is Caribbean.] 



54. Conus ravus [=C Califoniicus, lids.].

57. 0/«'//.-«M achates [ = 0. clavuhts, A. Ad., 1854]. 



G5. ColumheUa Sta.-liarburoisis [so named to correct the statement that California 

 was above the limit of the genus, proves to be a Mexican shell, and was 

 probably obtained at Acapulco. Having been redescribed by IJeeve from 

 perfect specimens, it may stand as C. Beerei\ 



60. Xitidtllu Gotddii. [Not to be confounded with Col. Gouldiana, Agass., -which 

 is probably Aim/cla.^ 



67. Fusus ambustuH [is a Califomian species. The type stands in Miis. Cum. as 

 F.fragosus, Rve., but does not answer to the diagnosis. The typical frat/oaii.1 

 is marked fragosus, var. F- anibustm appears absolutely identical with F. 

 clavatits, Brocchi, Mediterr^vnean. Some of the diagnostic marks are not con- 

 stant in the specimens]. 



Col. Jewett went to Panama, as a private collector, in January 1849, 

 spcmling ten weeks in that region, including Taboga. This was two years 

 hefore Prof. Adams's explorations. Thence he sailed to San Francisco, 

 where he spent four months in exploring the shore for about 50 miles 

 from the head of the bay. After labouring for a week at Monterey, he 

 spent ten weeks at Sta. Barbara and the neighbourhood, thoroughly exploring 

 the coast for fifteen miles as far as Sta. Bonadventura. It was here, at the 

 " Ilincon," after a violent southern storm, that he obtained the specimens of 

 Livona picoides, as well as many other rare species that have not been obtained 

 bj- any other explorer. *' The storm tore up the kelp to such a degree that 

 it formed a bank for many miles on the beach, from 10 to 20 feet broad, and 

 at least 4 feet deep. Jilany of the plants were more than 60 feet long and 5 

 inches in diameter, having the appearance of vast cables.'' Before his return 

 to the east, he also collected at Mazatlan (where he obtained some species 

 not included in the B. M. Catalogue) and at Acapulco. There can be no 

 doubt of the accuracy of the Colonel's observations at the time they were 

 made. Unsurpassed in America as a field-nala'oatolo2;ist. possessed of accurate
