introduced by man within comparatively recent years nor by the 

 vikings" but is a much older inhabitant of this continent. 



Ldnnberg (Arkiv for Zoologi, 3, 1906) discusses the systematic posi- 

 tion of the extinct Irish Elk. This is usually closely associated with 

 the common fallow deer. Lonnberg thinks that this association 

 rests almost exclusively upon the somewhat similar palmated antlers 

 but that in other and more ini])()rtant fciiturcs tlicre is more afliiiity 

 with the reindeer than with any other cervicorn, altliouo-h it pivsciiis 

 considerable specialization in its own Hue. 



Froriep gives (Verhandl. An atom. Gesellschaft, XX, 1906) a detailed 

 comparison of the eyes of vertebrates and tunicates and concludes 

 that both are derivable from a common ancestral condition which is 

 closer to the optic pit of the vertebrate than to the eye of the ascidian 

 larva. Two weeks later comes the Anatomischer Anzeiger (xxix, p. 

 52() Nov. 24, 1906) in which Metcalf discusses the relation of the ver- 

 tebrate eye to that of Salpa suggested by Redikorzew, and holds that 

 the views of the latter are untenable but he says "It may not unlikely 

 be true that the condition with a single anterior enlarginncnt of the 

 central nerve tube is ancestral (cf. Amphioxus and tlic tunicate tad- 

 pole)."
