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 parmila 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. lasvis 

 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.
