PATAGONIAN EXPEDITIONS : PALEONTOLOGY. 
agree completely with the common fossil form found on the mouth of the 
Santa Cruz River. 
Record of specimens : Mouth of Santa Cruz River, 25 sp. ; Mt. of Obser- 
vation, upper horizon, 14 sp. ; San Julian, Oven Point, 2 sp. ; 30 miles 
north of upper Rio Chalia, 22 sp. ; Shell Gap, Rio Chico, upper horizon, 
2 sp. ; Lake Pueyrreden, 600' above base, 1 7 sp. 
Distribution: Fossil: Santa Cruz and Jegua quemada, Patagonian and 
Suprapatagonian beds (v. Ih.). 
Recent: West coast of South America (Chili, Peru, and perhaps Cali- 
fornia), and East coast of Patagonia (coll. Hatcher: Punta Arenas, Cape 
Fairweather, Santa Cruz).

We possess three individuals, which are very high, and — although the 
shell is well preserved — it does not show any radiating ribs, but numer- 
ous concentric lamellae. They agree in the latter character apparently 
with the following species, but are very much higher. Among the 
material from 30 miles north of Rio Chalia, casts are found, which agree 
in form with this variety, but some of them show traces of radial ribs. 
To this variety may belong: Trochita parvula of Philippi (1887, p. 93, 
pi. 11, f. 2), from Navidad. Philippi had only a single small individual, 
which was apparently poorly preserved. And further, the var. Iceuis 
Gray ( 1 . c.), recent, Falkland Island may belong here, but it is said of 
to be smooth (without concentric lamellae). We possess this smooth 
form among the recent material collected by Mr. Hatcher at Cape Fair- 
weather.
