Natural History Tour in Norway. 171 



At Graven I found specimens of a small Clausilia, which I 

 consider the C. obtiisa of Pseiffer. It differs from the Clau- 

 silia minima Zeigler, in the very obtuse termination of the 

 upper whorls, a character of rare occurrence in this intricate 

 genus. 



From Graven we walked to Vossevangen through much 

 beautiful scenery. The pine forests were very extensive in 

 this district, with their usual inhabitant the Linnae^z. On the 

 way we observed ^erbascum nigrum and 5edum album for 

 the first time. Vossevangen is a considerable village, and 

 is the capital of the district of the same name. 



From Voss we directed our course towards the Sogne-fiord. 

 The country around Voss is formed of a mica slate, in which 

 no garnets were observed. It is probably a bed in the gneiss. 

 Between it and the gneiss at Tvinde is found a singular rock, 

 a sort of granular quartz, substratified. At the same place, 

 on the road side, lay a detached mass of hypersthene ; but 

 I did not see it in situ. One side of the valley of Stalheim 

 is bounded by hills of snow-white quartz, which are almost 

 bare, and present mural precipices, having a very singular 

 appearance at a distance, from their shining white colour. 



The valley of Stalheim is a great ravine of the most pic- 

 turesque character, in the middle of which rises the almost 

 isolated and inaccessible mountain of Jordan-nook. On 

 each side of the stair-like descent into the valley is a cataract 

 of the first magnitude. Stalheim is famous in Norway for 

 the number of the wolves found there ; and across the road, 

 in several places, we observed a rope suspended from a pole 

 on each side, which we were told was placed in that manner to 

 ward off the wolves, as their dislike is well known to any thing 

 suspended over their heads. 



At Gudsvanger we again took to water, and sailed down 

 the Heimdals-fiord, a branch of the Sogne-fiord. The scenery 

 resembled that of the Hardanger-fiord. During the morning 

 a large eagle flew over our heads. Instead of turning off with, 

 the road to Christiania we sailed the whole length of the upper 

 Sogne-fiord to Lystre, where we commenced ascending the 

 mountains of Haranger to cross into Gulbrandsdalen. The 

 peaks of the Haranger- feld are the highest in Norway ; their 

 elevation reaching above 8000 ft. As these mountains rise 

 immediately from the level of the sea, and are very preci- 

 pitous, they lose nothing of their height to the eye. 



After passing the night at Berger, a group of huts at an 

 elevation of about 2000 ft., we engaged a guide and ponies to 

 bring us to Lomb, in Gulbrandsdalen, a distance of near 

 40 miles, twenty of which were occupied in crossing an
