568 REPORKRT—1865. 
39. Trochus auripigmentum, Jonas. Panama. [Probably not from W. America. | 
17. Phasianella perforata, Phil. Mazatlan, Panama+TLh. compta, Gld.* Rather 
out of place + ; has neither form nor texture of Phastanella. [The aberrant 
form is due to the figured specimen being quite young; the adults in 
Brit. Mus. Col. prove the texture, colouring, and operc. to be normal. | 
Genus Stmpulopsis. This group, intermediate between Vetrina and Succinea, is 
stated to be peculiar to Brazil and Mexico, where Vitrina is not known. 
In the Monograph of Terebratulide, which is prepared with unusual care, 
and the general introduction to which is well worth attentive perusal by all 
students, occur the following species which bear upon the West Coast fauna 
or synonymy :— 
2. Terebratula (Waldheimia) dilatata, Lam.,=T. Gaudichaudi, Blainy. “Str. 
Magellan,” teste Gray, in Brit. Mus. Cat., without authority. [The E. E. 
specimens varied considerably in outline ; and according to Darwin, and 
what we know of the variations of fossil species, it is quite possible to 
believe that this and the next species had a common origin. The great 
development of this most interesting form in the cold regions of South 
America is extraordinary. | 
3. Terebratula (Waldheimia) ylobosa (Val.), Lam., from type. = 7. Californica, 
Koch. “California, Coquimbo. Californian form well known; small 
specimen in Mus. Taylor, marked ‘de Coquimbo.’” [There appears no 
authority for the general belief that this fine species is Californian. It was 
taken in abundance by the naturalists of the i. S. E. E. at Orange Bay, 
Magellan. The Californian shell, which is probably the original Cal- 
fornica, Koch. (not of authors) is a distinct species, teste Rve. from Dr. 
Cooper's specimens. 
7. Lerebratula (Terebratulina) radiata, Rve., Mus. Cum. ? Straits of Corea, 
Belcher. {Very like the adult of 7. cawrina, Gld. | 
ll. Zerebratula ura, Brod. Bay of Tehuantepec, Guatemala; 10-12 fms. sandy 
mud, on dead bivalve, Capt. Dare. Mus. Cum, and De Burgh. [The 
analogue of 7. vitrea, Med. | 
16. Terebratula (Terebratulina) Japonica, Sby., = T. angusta, Ad. and Rye. Corea, 
Japan. “Represents 7. caput-serpentis, and probably the same.” 
23. Terebratula physema, Val., MS. (unique), Coquimbo.  Gaudichaud, 1853. 
May be a colossal, broadly inflated var. of globosa. 
6. Orbicula Cumingit, Brod. {Besides information in Rep. pp. 188, 244, is given ] 
Is. Cana, Guatemala; sometimes 6-18 fms., Cuming. O. strigata, Tool 
is a less-worn state of this species. [The type-specimens of Discina stri- 
gata in Brit. Mus., on Pecten ventricosus, appear very distinct, and are 
unusually shelly for the genus. | 
excluding Ziziphinus (= Calliostoma), Mr: Reeve “ contrives to place” in Zrochus animals 
shown by the opercula to belong to different subfamilies, as though we knew no more than 
in Lamarck’s days ; his motley group containing Imperator (= Stella, H. and A. Ad.)+ 
Lithopoma + Guildfordia+ Chrysostoma + Bolma + Modelia 4+ Polydonta + Tectus+- 
Pomavlax+ Astralium+ Pachypoma+ Uvanilla. Also ina family the genera and species 
of which are mainly recognized by the base and mouth, most of the shells are only figured 
on the back. Very often the characters of the aperture are not even stated. Remarkable 
liberties are, moreover, sometimes taken with geographical facts, to the great astonishment 
of Americans, who expect even their schoolboys to avoid such statements as at sp. 57, Tr. 
diminutivus, Rve., “ Oahu Islands ;” and at sp. 1, Linxgula ovalis, Rve., “from W. H. 
Pease, Esq., residing at Honolulu, one of the Sandwich Islands.” 
* P, compta is a distinct Californian species ; its Pvarieties pass into pulla. If Mr. 
Reeve can be followed in uniting to pulla, pulchella, Recl. ;-++ affinis+ tessellata+pulchella 
+concinna, C. B. Ad. ;+tenuis, Phil. ;+intermedia, Scacchi ;+ Capensis, Dkr. ;+elon- 
gata, Krauss, Gould’s species should.join this goodly company, rather than perforata. 
The same standard of union followed among the large shells would greatly lessen the size 
of this costly work. : 
+ So is Phasianella rubra, Pease MS., sp. 18, which belongs to Aleyra, A. Ad. allied 
to Euchelus.
