546 REPORT 1863. 



290. Calliostoma M' Andrea is the normal state, of which C. Leanum is the pale 



variety. 

 292. Mr. Pease considers that T. Byronianus represents a Polydonta from the Pacific 



Islands. 



313-316. The non-pearly Liotia are Conradia, A. Ad. 

 322, 323. Mr. A. Adams thinks that the " Eihalia " amplectam is probably the 



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

 338. Crepidula adunca, Cpr. (non Sby.,=softVa. H.d.s., = rostrifonms, Gld.). The 



tropical shell is C. uncata, Mke.~ = (7. rostrata, C. B. Ad'., Rye. 

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

 354. Vermetus eburneus, Rve.,= V. ?glomeratm, C. B. Ad., non Lam. The note to 



Ccecum, Brit. Mus. Cat. p. 314, should read : " Of a fourth group, Meioceras, 



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



Grignon. The earliest Crecid is the Eocene genus Strebloceras." Vide 



Mpn. Cfecidaj in P. Z. S. 1858, pp. 413-444. 



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



East Indian species, = C. obesum, feby. sen. 



388. This is not the C. interruptum of C. B. Ad., Sby., and Mus. Cum. (Jiodie), 



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

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



389. Vertayus should be changed into Rhinoclavis, Swains. ; v. note to 289. 

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



lt Triforis" infrcquens of C. B. Ad. is a dextral shell, = Cerithiopsis tuber- 

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

 of T. inconspicuus. 



398. Litorina Pliilippii=L, ?parwila, C. B. Ad., non Phil.,=Z. diibiosa, C. B. Ad., 



nom. prov. 



399. = Litorina pullata, Cpr. ; described from Cape St. Lucas specimens. 

 409. Probably = Rissoina jirmata, C. B. Ad.,-f-K. scalariformis, C. B. Ad. 



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



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

 ences. 



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



non Alder. 



417. Fresh specimens prove this to be not a dead Hydrobia ulvce, but a Barlecia. 



It appears on the Californian coast, as . subtcnuis. 



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

 422. Is a Gemetta, teste A. Ad. 



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



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

 Fossarus. 



437. Luponia spurca. This shell is quite distinct from L. albuyinosa, 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, 446. Cancellariadfs should be removed to Proboscidifera, teste A. Ad. 



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

 which is certainly the easiest way of meeting the difficulty. 



453. Myurella rufocinerea= T. rudis, Gray, teste Rve. 



477. Conns reyalitatis-^ C. purpurascens, var. Most Cones vary in the same manner. 



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

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

 parison with shells 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 diagnosis, 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 minute Mazallan shells, all of which have been drawn under the micro- 

 scope.
