534 REPORT 1863. 



Aiepoit, 216. Scalaria Ochotensis [appears an aberrant Opalia; but is the genus 

 Adrsa of Mb'rch, closely allied to Mesalia, teste A. Ad.]. 



216. Crepidula Sitchana [is figured like the young of grandis ; but the 

 specimens in Mus. Cum., when compared with the similar stage of 

 C. excavata, display no differences either inside, outside, or in the 

 nuclear whorls]. 



216. Crcpidula minuta [appears the young of C. nacicelloides, Nutt.] 



216. Crepidula grandis [fossil at Sta. Barbara, = C. princeps, Conr. Can 



hardly be distinguished from very fine specimens of C. fornicuta, 

 sent from Halifax, Nova Scotia, by Mr. Willes]. 



217. Trichotropis cancellata, lids, [is quite distinct from T. borealis]. 



217. Pur pur a decemcostata, ~Midd.i=P.canaliculata, Duel. Var. = P. at" 



tenuata, Rve. Var. = P. analoga, Fbs. ] 

 217. Tritonium (Trvphon) clathratum, Ln. [is distinct from the shouldered 



M. midticostatus, Esch.,= Gunneri, jLov.]. 



217. Tritonium (Fusus) decemcostatum [=C%r. Middendorffii, Cooper = 



Chr. liratus, Martyn.] 



218. Tritonium (Buccinum} cancellation [Midd., non] Lam. [=Pn'ene 



Oreyonensis, Redf. P. cancellata is the Cape Horn species. Some 

 specimens in alcohol in Sir E. Belcher's collection, however, said 

 to be from Icy Cape, greatly resemble the southern shell]. 

 218. Tritonium (Poltia) scabrum [is exclusively a S. American shell. Dr. 

 M.'s shell may have been Ocinebra, var. asperd], 



218. Pecten rubidus, Hds. [non Martyn, = P. Islandicus, Mull. Midd. 's pi . 13. 



f. 1-3 are marked in expl. of plates " Islandicus, var. Behringiana ; " 

 they are probably (" rubidus, ?var.") Hindsii. But the figs. 4-6 

 are certainly the young of Hinnites giganteus~\. 



219. Venerupis gigantea. [Decorticated specimens of Saxidomus sqitahd-m.~] 

 219. Petricola gibba. [Elongated form ofcylindmcea, Desh., = carditoides^oz J 



219. Machcera costata. [The figures represent M. patula, Dixon.] 



220. Cingida minuta [" is quite distinct from Hydrobia ulvce" teste Gld.]. 

 220. Velutina cryptospira. [Probably a LamellariaJ] 



220. Purpura Freycinettii, Desh. [is quite distinct from attenuata, Rve. It 



is doubtful whether Midd.'s shells belong to Desh.'s species]. 



221. Terebratula frontahs, Midd. 1851, named in 1849, [may be the young 



of Waldheimia Coreanica, Ad. & Rve., 1850, = Terebratella miniata, 

 Gld., 1860, teste A. Ad., Rve.]. 

 221. Astarte lactea, Gld. [is distinct from A. Scotica, teste Gld.]. 



221. Tellina fusca, Say [is distinct from T. solidula, though it may= T. bal- 



thica ; teste Gld. Macoma inconspicua, Br. & Sby., is distinct from 

 both]. 



222. Lyonsia hyalina [is distinct from L. Norvegica']. 



222. Machcera costata, Say. [Dr. Gould does not believe that any of Midd.'s 

 synonyms belong to this species. Solcn medius, in Br. Mus., appears 

 ^= S. ambiguus, Lam., as figured by Swains. It is not a MachteraJ] 



45. Samarang. Litorina castanea, Ad. & Eve., 1850. " Eastern Seas," 

 p. 49, pi. 11. f. 8 [appears identical with L. Sitchana, Phil.]. 



46. E. B. Philippi. Columbella tceniata, Phil., 1846 [is probably identical 

 with Anachis Gaskoinei, Cpr. But C. tceniata, Ad. & Rve., 1850, is perhaps 

 a Nitidella']. 



47. The " Mexican War Naturalists." These were Major Rich and Lieu.}. 

 Green. Col. E. Jewett was not connected with the war, as would be supposed 

 from the introduction to Dr. Gould's pamphlet. The following corrections 

 apply to the new species tabulated in Rep., pp. 226-228. The species of Gould 

 bear date April 1852 (tesie Otia, p. 184) and Nov. 1851 (Otia, p. 210) ; the 

 others, July 1856. 



No. 



3. Corbula poly chroma [=C. biradiata, var.]. 



7. Tettina lersa \ = Macoma nasuta, jun. CaL, not Pan.],
