Hertil kommer et Antal Ungdomsfoi-mer (Motella ar-

 boj Grad af Sandsynligbed tilbore denne Art. og som lige-

Beeren Eiland, 4 full-grown specimens." only are known to 

 exist of this species, which, as previously stated, were all 

 obtained off the coast of Greenland ; they are preserved 

 in the Zoological Museum at Copenhagen. 



The individuals last obtained were taken at a con- 

 siderable depth (6— Too fathoms), and in water of the 

 temperature of. ice. 



There occur besides a number of forms in the earlier 

 stages of growth (Motella argmtata, Reinh.), which, as ex- 

 plained above, may be referred with a high degree of pro- 

 bability to the species in question ; the sj^epimens of these, 

 too. were taken on the coast of Greenland (1830 — 1840), 

 and are most of them preserved in the Copenhagen Mu- 

 seum, some in the MViseums of Berlin and -Vienna.
