ORTMANN : TERTIARY INVERTEBRATES. 263 



The Trochita mentioned by Philippi is identified as T. corrugata, and the 

 Terebra, given as undulifera by Rochebrune and Mabille, as T. costellata. 



Other species mentioned by v. Ihering as new, have been recognized as 

 synonyms of known forms ; they are : Pecten quemadensis, Cucullaria tri- 

 dentata, Nucula tricesima, Gibbula fracta, T^lrritella tricincta, Valuta phi l- 

 ippiana and quemadensis. 



Thus v. Ihering adds to what he calls Patagonian and Suprapatagonian 

 fauna: 48 species, which brings up the total number of species known 

 from these beds to 95. 



Of the 48 species, 36 are represented in our collection. 



In a second contribution, in 1899, v. Ihering added the following spe- 

 cies, all from the typical Patagonian beds : 



1. Pinna semicos tails var. magellanica. 7. Tritonium bicegoi. 



2. Crassatella kokeni (Crassatellites /.). 8. Siphonalia dilatata (S. domeykoana). 



3. Lucina ortmanni. 9. Valuta triplicata. 



4. Tellina santacmzensis. i o. Valuta pilsbryi ( V. domeykoana). 



5. Tellina tehuelcha. 11. Pleurotoma discors (P. subcequalis). 



6. Glycimeris nucleus (Panopea .). 



Of these 1 1 species, 8 are found in our collection. Venus cf. uncinata, 

 Pyrula hombroniana are extremely doubtful, while Pecten fissicostalis is a 

 synonym of P. geminatus. 



This contribution brings up the number of well-known Patagonian 

 species to 106. 



Finally Cossmann, in 1899, describes the following "Suprapatagonian" 

 species : 



1. Lcptothyra philippii. 8. Trichotropis patagonica. 



2. Solar ie I la dautzenbergi. 9. Fossarus pillula. 



3. Calliostoma pararatum. 10. Odontostomia euryope. 



4. Calliostoma santacruzense. 1 1 . Triton obliteratus. 



5. Gibbula diametralis. 12. Urosalpinx leucostomoides (U. cossmannf). 



6. Gibbula iheringi. 13. Peratotoma ihcringi. 

 j. Gibbula margaritoides. 



He gives to the Fissurella already mentioned by v. Ihering the name 

 of F. eurytreta. Odontostomia synarthrota and Turbonilla iheringi are 

 synonyms. 



Of these 13 species, onty 6 are represented in our collection.
