380 Ortmann — Invertebrate Fossils from Patagonia. • 



9. Cardita incequalis Phil. This species is the most abun- 

 dant form of the genus at Santa Cruz. Large specimens of it 

 have been sent by v. Ihering to the Princeton Museum under 

 the name of 0. patagonica Sow., and thus it seems apparent 

 that C. patagonica of v. Ihering is identical with G. inmqualis 

 of Philippi. 



10. Cardita patagonica Sow. We possess only the small 

 variety, called by v. Ihering in 1899 (Neues Jahrb. Miner., 

 etc.) C. pseudopatagonica. I believe that this is really the 

 true patagonica of Sowerby. 



11. Venus navidadis Phil. Already v. Ihering suggests 

 that his V. striatolamellata may be identical with this species. 

 I think that is right. 



12. Dentalium sulcosum Sow. Synonyms of this species 

 are : D. majus Sow., and D. patagonicum Rochebrune and 

 Mabille. 



13. Gibbida dalli v. Iher. G. fracta v. Ih. seems to be 

 nothing else than the young of this species. 



14. Infundibidum clypeolum (Peeve). Called by v. Ihering 

 Trochita magellanica Gray. But the specific name of Reeve 

 has the priority. 



15. JVatica ovoidea Phil. I take N.famula Phil, for the 

 young stage of this species. 



16. JVatica secunda Rochebr. and Mab. The specific name 

 secunda of Rochebrune and Mabille was published in 1885 

 (Bull. Soc. Philom. Paris, ser. 7, vol. ix) and has the priority 

 over JV. obtecta Philippi, 1887. 



17. JVatica darwini v. Ihering. According to v. Ihering 

 the specific name of JV. solida, Sow. has been preoccupied by 

 Blamville. He attributes the name darwini to Hutton, but I 

 cannot find it in any of the publications of Hutton. 



18. Gdontostoniia suturalis v. Ihering. O. synarthrota 

 Cossmann (Journal de Conchyliology, 1899) is indistinguishable 

 from this species. 



19. Turbonilla cuevensis v. Iher. T. iheringi Cossmann 

 (ibid.) is indistinguishable from this species. 



20. Struthiolaria chilensis Phil. The extensive material at 

 hand leaves it beyond doubt that S. ameghinoi v. Iher. is a 

 synonym of this species. 



21. Fusus domeylcoanus Phil. Siphonalia dilatata var. 

 subrecta of v. Ihering (1899) is this species. 



22. Trophon patagonicus (Sow.). Abundant material of 

 this species enables me to pronounce T. laciniatus santacru- 

 zensis v. Ihering as a form of this species, which is connected 

 with it by numerous transitions. 



23. Urosalpinx cossm.anni nom. nov. For 77. cf. leucosto- 

 inoides Cossmann, non Sowerby.
