39. Irnchoi anripigynenimn, Jonas. Panama. [Probably not from W. America.] 

 17. PhasiaitcUi! perforata, Phil. Mazatlan, Panama +J7i. cow?^ji'«, Gld.* Rather 

 out of place f ; has neither form nor texture of Phasianella. [The aberrant 

 form is due to the figured specimen being quite young; the adults in 

 Brit. Mus. Col. prove the texture, colouring, and nperc. to be normal.] 

 Genus Simpulopm. This group, intermediate between Vitrina and Succinea, is 

 stated to be pecidiar to Brazil and Mexico, where Vitrina is not known. 



In the Monograpb of Terebratulidce, which is prepared with unusual care, 

 and the general introduction to which is well worth attentive perusal by all 

 students, occm- the following species which bear upon the West Coast fauna 

 or synonymy : — 



2. Terehratnla (Waldheimia') dilatata, 1^0,111., = T. GaudicJiaudi, Blainv. "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.] 



5. Terehratida ( Waldheimia) i/lobo$a (Val.), Lam., from type. = T. Californica, 



Koch. " California, Coquimbo. Californian form well known ; small 

 specimen in Mus. Taylor, marked ' de Coqjiimbo.' " [There appears no 

 authority for the general belief that this fine species is Californian. It was 

 taken in abundance by the naturalists of the U. S. E. E. at Orange Bay, 

 Magellan. The Californian shell, which is probably the original Cali- 

 fornica, Koch, (not of authors) is a distinct species, teste Kve. from Dr. 

 Cooper's specimens.] 

 7. Terehratida (Terebratidina) radiata, Rve., Mus. Cum. ? Straits of Corea, 

 Belcher. [Very like the adult of T. caurina, Gld.] 



11. Terehratida uva, Brod. Bay of Tehuantepec, Guatemala; 10-12 fms. sandy 

 mud, on dead bivalve, Capt. Dare. Mus. Cum. and De Burgh. [The 

 analogue of T. vitrea, Med.] 



16. Terehratida (Terebratidina) Japonica, Shj., = T, angitsta, Ad. Rud Jive. Corea, 

 Japan. "Represents T. caput-serj)entis, and probably the same." 



23. Terehratida phijsema, Val., MS. (unique), Coquimbo. Gaudichaud, 1833. 

 May be a colossal, broadly inflated var. oi glohosa. 



6. Orbiczda Cumingii, Brod. [Besides information in Rep. pp. 183, 244, is given] 



Is. Cana, Guatemala ; sometimes 6-18 fms., Cuming. O. strigata, Brod., 

 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 2mj?AiwM*(=CaZi?Jo«^OMa), Mr. Reeve "contrives to place" in TrocJius ammsls 

 shown by the opercula to belong to diflerent subfamilies, as though we knew no more than 

 in Lamarck's days ; his motley group containing Imperator { = Stella, H. and A. Ad.)-j- 

 Lithopoma -{■ Guildfordia-\- Chrysostoma -|- Bolma + Modelia -f- Polydonta -\- Tectus-\- 

 Pommda.v -\- Astralium-^ Pachypoma-\- Uvandla. Also in a 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. 

 dimimitiviis, Rve., " Oahu Islands ; " and at sp. 1, Lingula ovalis, Rve., " from \V. U. 

 pease, Esq., residing at Honolulu, one of the Sandwich Islands." 



* P. compta is a distinct Californian species ; its Pvarieties pass into pnlla. If Mr. 

 Reeve can be IbUowed in uniting toptdla, pulchella. Reel. •,-\-ajffinis-\-tessellata-\-pidcheUa

 gata, Krauss, Gould's species should join this goodly company, rather than perforata. 

 The same standard of union followed among the large sheUs would greatly lessen the size 

 of this (!Ostly work. 



t So is fhasianella ruhra^ Pease MS., sp. 18, which belongs to Alci/ra, A. Ad. j allied 

 to Uuckelus,
