DTJPONT CAYEEN-S OF THE LESSE. 29 



section presented by one near the route from Hulsonniaux to Celles, 

 in ascending order : — 



5. Rolled pebbles of Ardennaise origin cemented by gravel. 



4. Yellow clay with dolomitic blocks. 



3. Loess. 



2. Alluvium formed of alternating veins of sands and clays, like Lehm. 



1. Like No. 2, but reonanies and mixed with vegetable detritus. From this 

 bed the author obtained some flint knives and a little sandstone hache, polished 

 and with an irregular surface. 



Niitons cles Gendron. — The cavern of Nutons desGendron is situated 

 on the right bank of the Lesse, about 1| mile (in a direct line) from 

 the Purfooz cavern. It is excavated in a schistose bed with alter- 

 nating calcareous bands, belonging to the " Psammites of Condroz." 

 The length of the cave is 15 yards, and it has a breadth at the 

 opening of 2-1 yards. At the entrance is a mould formed by the 

 decomposition of leaves, below which is found yellow clay with 

 blocks of schist, without bones or works of art. The mould at a 

 distance of 8 yards from the entrance was overlain with stalagmite, 

 and contained human bones which belonged to no less than seventeen 

 skeletons. Although the bones were broken, the workmen were 

 able to observe that fifteen of the skeletons were arranged longi- 

 tudinally along the cavern in six rows of two or three, varying 

 according to the vsddth of the cavern, with two skeletons placed 

 transversely, the heads of the longitudinal skeletons being towards 

 the mouth of the cave. A very small splinter of chalk-flint in the 

 shape of a plate was found, together with three fragments of coarse 

 pottery. 



On the slope of the escarpment, immediately below the entrance, 

 two great blocks of transported schist were dug up, one measuring 

 5 feet by 2| feet, the other 3 J feet by one foot. 



Among the human remains were found bones of the Pox, Badger, 

 Fowl, &c. The workmen also found a modern metal button with 

 inscription, but without a date. 



After ha™g noticed the great number of human bones, especially 

 fragments of the upper and lower jaw, and given detailed descriptions 

 of the bones, the author states as his opinion that the remains are 

 in a sepulchral cavern. The exact age, however, to which they 

 belong is difficult to determine. The skeletons belong to a period 

 posterior to the age of the Eeindeer, because in the province of 

 IS'amur remains of that age are always found below the yellow clay, 

 the mould in this instance being above. M. Dupont therefore 

 concludes that the skeletons were deposited in the cavern at an 

 epoch posterior to the age of the Eeindeer and anterior to the 

 Bronze age, and refers them to the Polished-Stone period (age de la 

 jpierre polie), [A. S.] 



On a Neav genus of Cephalopohs. By Chev. P. von Hauee, 



[Proceed. Imp. Acad, of Vienna, December 14, 1865.] 



This genus, for which the author proposes the name of " Chorisio- 



ceras,'^ bears a shell similar in form to that of Crioceras^ with the
