ORTMANN : TERTIARY INVERTEBRATES. 
263 
The Trochita mentioned by Philippi is identified as T. corrugata, and the 
Terebra , given as undulifera by Rochebrune and M abide, 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 , Turritella tricincta , Voluta fthil- 
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 semicostalis var. magellanica. 
2. Crassatella kokeni (Cras satellites k ). 
3. Lucina ortmanni. 
4. Tellina santacruzensis . 
5 . Tellina tchuelcha. 
6 . Glycimeris nucleus (Panopea nl). 
7. Tritonium bicegoi. 
8. Siphonalia dilatata (S. doineykoand). 
9. Voluta triplicata. 
1 o. Voluta pilsbryi ( V. doineykoand). 
1 1 . Pleurotoma discors {P. subcequalis ). 
Of these 1 1 species, 8 are found in our collection. Venus cf. uncinata , 
Pynda hombroniana are extremely doubtful, while Pecten fissicostalis is a 
synonym of P. gen tin a fits. 
This contribution brings up the number of well-known Patagonian 
species to 106. 
Finally Cossmann ) in 1899, describes the following “Suprapatagonian” 
species : 
1. Leptothyra pliilip pii. 
2. Solariella dautzenbergi. 
3 . Calliostoma pararatum . 
4. Calliostoma santacruzense. 
5. Gibbida diametralis . 
6 . Gibbida iheringi. 
7. Gibbida 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, only 6 are represented in our collection. 
8. Trichotropis patagonica. 
9. Foss arus pillula. 
10. Odontostomia euryope. 
1 1 . Triton obliteratus. 
12. Urosalpinx leucostomoides ( U. cossmanni ). 
1 3 . Peratotoma iheringi.
