II. — Note ox Graptolites from Peru. 

 By E. T. Xewtox, F.R.S., F.G.S., etc. 



ME. HERBERT J. JESSOP, who has recently returned from 

 a journey in Eastern Peru, kindly placed in my hands, for 

 examination, some specimens of graptolites which he had obtained 

 on the River Macho, one of the tributaries of the Inambari, near the 

 celebrated mountain Capac Oreo, or Monte Bello, in the province of 

 Carabaya, Peru (lat. 13° 40' S. ; long. 70° 10' W.). The locality is 

 situated on the north-east of the main watershed, and the rivers flow 

 eventually into the Amazon. The difficulties of travelling make it 

 likely that a long time will elapse before other specimens are 

 forthcoming from this locality ; it seems desirable, therefore, that 

 some account of these should be published.

Mr. Jessop tells me that the pieces of black shale containing the 

 graptolites wei"e portions of a mass of rock about two feet square 

 and one foot thick, which was not found in place, but loose upon 

 the ground ; its unrolled and unweathered condition convincing him 

 that it could not have travelled far from the parent bed. Similar 

 shaly rocks are in place near by, but he was prevented from making 

 a careful exploration. The specimens obtained seemed to him 

 sufficiently interesting to be brought home, notwithstanding that 

 everything had to be carried by the men for many miles, the place 

 being inaccessible for horses or mules.
