546 REPORT — 1863. 



290. CalUostoma M'Jndreee is tlie normal state, of wMch C. Leanum is tlie pale 



vfiriGtv. 

 292. Mr. Pease considers that T. Byronimiua represents a PoZt/cZonfo from the Pacific 



Islands. 

 31.3-316. The non-pearly Liotim are Conradia, A. Ad. _ , , , ,, 



322, 323. Mr. A. Adams thinks that the " Mhalia " ampledans is probably the 



young of " Teinostoma" a., as suggested in Brit. Mus. Cat. p. 253. 

 S38. Crepidula adunca, Cpr. (non 'S^s.,=solida, IUs.,=rostriformis, Gld.). Ihe 



tropical shell is C. micata, Mke.,= C. rostrata, C. B. Ad., Eve. 

 341. Should stand as C. squama : v. note on C. B. Ad. no. 351. 

 354. Venndus ebumeus, Rve.,= V. fglomeratm, 0. B. Ad., non Lam. The note to 



Ccscu7n, Brit. Mus. Cat. p. 314, should read :—" Of a fourth group, Meioeeras, 



three species are known from the Caribbean Sea, one of which is fossil at 



Gri"-non. The earliest Coecid is the Eocene genus Streblocei-as." Vide 



MoS. Cfecidte in P. Z. S. 1858, pp. 413-444. 

 387. Cerithimn irroratum, Gld. (teste type sp. in Mus. Smiths.), is a very distmct 



East Indian species, = C. ohesum, Shy. sen. 

 383. Thi^ is not the C. interniptum of C. B. Ad., Sby., and Mus. Cum. (hodie), 



which latter is the roughened form of C. stercus muscarum, Val. C. Galla- 



paginis is the rough form of C. interruptum, Mke. 

 389. Veiiagus should be changed into Rhinodams, Swains. ; v. note to 289. 

 391-393. The genus Triforis should be removed to CeritMopsidce. _ The true 



" Triforis" infrequens of 0. B. Ad. is a dextral &lo.el\,= Cerithiopsis tuber- 



cidoides, no. 557. The shell here doubtfully affiliated is probably a variety 



of T. inconspicuus. 



398. Liiorina Fldlippii-=L. ?parvida, C. B. Ad., non Phil.,=Z. dubiosa, C. B. Ad., 



nom. prov. 



399. =Litoi-ina 2)uUata, Cpr. ; described from Cape St. Lucas specimens. 

 409. Probably =-Rissoma_^VOTato, C. B. Ad.,-|-i?. scalarifonnis, C. B. Ad. 



411. " Not a JBarleeia," teste Jeffr. MS. It seems, however, too closely allied tc 



B. rubra to create a fresh genus for it, unless the animal should display differ- 

 ences. 



412, 413. Belong to Fenella, A. Ad.* F. excurvata=? Rissoa inconspicua, C. B. Ad., 



non Alder. 



417. Fresh specimens prove this to be not a dead Hydrobia uIv(b, but a Barleda. 



It appears on the Califomian coast, as B. subtenuis. 



418, 421. Are very similar, and possibly conspecific forms of Cythna, A. Ad. 

 4S-2. Is a Gemella, teste A. Ad. 



426, 427. Belong to Styliferina, A. Ad. 



430 ci seq. Some of these forms may rank with Gottoina, A. Ad., and thus approach 

 Fossarus, 



4Si7. Luponia spiirca. This shell is quite distinct from L. albuginosa, to which it 

 was supposed to belong by Dr. Newcomb. It is probably a ballast specimen. 



438. Quite distinct from the Panamic A. punctulata. 



445, 4-16. Cancellariadce should be removed to Proboscidifera, teste A. Ad. 



450-452. Mr. Reeve unites all these species, with several others, to M. variegata ; 

 which is certainly the easiest way of meeting the diificultj'. 



453. MyweUa rufodnerea=T. rudis, Gray, teste Eve. 



477. Conus regalitatis= C. purpurascens, var. Most Cones vary in the same manner. 



484. Tormia variegata. Mr. Hanley restores to this shell the uncomfortable name 

 of Chemn. (perspediviuncula), and unites to it areola, Desh. A careful com- 

 parison with sheUs from the Pacific Islands (teste Pease's specimens) proves 

 them to be completely identical. The " specific " names of Chemn., when 

 simply the second word of the diag-nosis, can hardly claim precedence. 



486. The genera in this family have lately been revised by Mr. A. Adams. A 

 large number of his Japanese groups are here represented. This species ■ 



* The generic names here given were assigned by Mr. A. Adams, who kindly examined 

 the figures of the mmute MazaLlan shells, all of wliich have been di-awn under the micro- 

 scope.
