Scrobicularia piperata Bell. only occurs in small speci- 

 mens of an ovate shape. 



Mya arenaria L. forma typica was rather common. 

 Length 57 mm. 



Litiorina littorea L. Rather common. We as a rule, how- 

 ever, find this species to be represented by juvenile specimens. 



Littorina obtusata L. forma typica. 

 Nassa reticulata L. forma typica. 

 Balanus balanoides L., Darw. 

 Spirorbis sp. 



Along the shore-line we in this place find a very fine 

 beach consisting of rolled stones, shells, and sea-weed to the 

 height of about half a metre above sea-level and forming a 

 sterile belt four metres broad. Then we meet with a belt about 

 six metres broad rising to the height of one metre and a half 

 above sea-level in which place we meet with a very prominent 

 line of marine erosion separating the last mentioned flat and 

 grass-grown belt from the higher, more eroded and wavy ground 

 the origin of which is manifested in the clayey consistence and 

 abundance of stones together with the thickly-strewn large 

 boulders and erratic blocks. 



Elsewhere we, in other respects, find the deposit as well as 

 the topography in this place to be nearly analogous to that in 

 the surroundings of the above described locality of Framnes. 

 At Charlottenberg we first meet with a clay-deposit of bluish- 

 grey colour and mixed with gravel and ice-scratched stones to 

 the thickness of between four and five metres; sometimes also 

 various clay concretions are imbedded in the morainic mass 

 that seems to be of fluvio-glacial origin directly deposited at 

 the sea-bottom of which fact the rich occurrence of arctic shells 

 give a clear evidence. The following species were 'collected in 

 this locality: — 



Nucula tenuis Mont. forma typica and var. expansa. 

 Portlandia arctica Gray var. siliqua the size of which 

 will be proved by some measurements tabulated below: —
