568 REPORT — 1863, 



39. Irochus auripigmentum, Jonas. Panama. [Probably not from "W. America.] 

 17. Phasianella perforata, Fhil. Mazatlan,Panama+PA. cojjipto, GH.* Eatber 

 out of place t ; baa neitber foj-m nor texture of Phasianella. [Tbe aberrant 

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

 Brit. Mus. Col. prove tbe texture, colouring, and operc. to be normal.] 

 Genus Simpulopsis. Tbis group, intermediate between Vitrina and Succinea, is 

 stated to be peculiar to Brazil and Mexico, wbere Vitrina is not known. 

 In tbe Monograph of Terelratulidm, wbiob is prepared with unusual care, 

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

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

 or synonymy : — 



2. Terebratula (Waldheimia) dilatata,'L&ra.., = T. Gaudichaudi, Blainv. "Str. 

 Magellan," teste Gray, in Brit. Mus. Cat., without authority. [The E. E. 

 specimens varied considerably in (Jutline ; and according to Darwin, and 

 what we know of the variations of fossil species, it is quite possible to 

 believe that tbis and tbe next species bad a common origin. Tbe great 

 development of tbis most interesting form in tbe cold regions of South 

 America is extraordinary.] 

 ] 3. Terebratula ( Waldheimia) ylohosa (Val.), Lam., from t3'pe. = T. Califomica, 

 Koch. "California, (joquimbo. Califomian form well known; small 

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

 authority for tbe general belief that this fine species is Califomian. It was 

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

 Magellan. Tbe Califomian shell, which is probably the original Cali- 

 fomica, Koch, (not of authors) is a distinct species, teste Bve. from Dr. 

 Cooper's specimens.] 

 ' 7. Terebratula (Terebratulina) radiata, Eve., Mus. Cum. ? Straits of Corea, 

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



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

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

 analogue of 1\ vitrea, Med.] 



16. Terebratula (Terebratulina) Japonica, Sby., = T. angusta, Ad. and Eve. Corea, 

 Japan. "Eepresents T. caput-serpentis, and probably tbe same." 



23. Terebratula physema, Val., MS. (vmique), Coquimbo. Gaudichaud, 1833. 

 May be a colossal, broadly inflated var. of globosa. 

 G. Orbieida Cumingii, Brod. [Besides information in Eep. pp. 183, 244, is given] 

 Is. Cana, Guatemala; sometimes 6-18 fms., Cuming. 0. strigata,Bvod., 

 is a less-worn state of this species. [Tbe tj'pe-specimens of Discina stri- 

 gata in Brit. Mus., on Peeten ventricosus, appear very distinct, and are 

 unusually shelly for tbe genus.] 



excluding Zisiphinus (=CaUiosfo>na), Mr. IReeye" contrivesto^lace" in Trochus animals 

 shown by the operoula to belong to different subfamilies, as though ive knew no more than 

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

 lAlhopoma •{■ Guildfordia-\- Chrysostoma -)- Bolma + Modelia -\- Polydonta -)- Tectus-\- 

 PQmaulax-\-Astralmm.\-Pachypoma-\- Uvanilla. 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 

 oti the back. Very often the characters of the aperture are not even stated. Kemarkable 

 bijarties are, moreover, sometimes taken with geographical facts, to tbe great astonishment 

 of Americans, who expect even their schoolboys to avoid such statements as at sp. 57, Tr. 

 diminutivus. Eve., " Oahu Islands; " and at sp. 1, lAiigula ovalis, Eve., " from W. H. 

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



* P. compta is a distinct Califomian species ; its Pvarieties pass into pvlla. If Mr. 

 Keeve can be followed in uniting lopulla, pidchella, Reel. y+affinis+tesseUata+pulcIiella 

 -\-concinna, C. B. Ad. j+ifm«w, Vhi\. i+iuiermedia, Scaechi j-t-Capejmi, Dkr. ;+e/on- 

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

 The same standard of union followed among the laj-ge shells would greatly lessen the size 

 of this costly work. 



t So is fhasianella rubra, Pease MS., sp. 18, which belongs to Alcyra, A. Ad. j allied 

 to Mwhelua,
