\ anhoffen (1906) notes A. limbctta from Greenland; I am 
inclined to think, this was owing to a confusion because of the 
superficial likeness between this form and the Greenlandic A. fla- 
vidula in regard to the colour and the mode of branching of the 
canals. 
In the mate rial from the “Tjalfe” I have found two small 6- 
radiate specimens.

In the material of the expedition five specimens of Cyanea are 
preserved; they have the following diameters: 1—1,5—2—4 —11 cm. 
The two largest specimens agree fairly well with Cyanea arctica 
Pér. & Les.; the 16 marginal lobes are somewhat longer than 
usual in C. arctica , but not as long as in C. capillata, and are very 
slightly scalloped as in C. arctica. The three small specimens 
lack the pointed aboral papillæ, characteristic for the young C. 
arctica ; these papillæ are said to be the most characteristic differ¬ 
ence of C. arctica Pér. & Les. from C. capillata Eschsch. The 
present specimens, on the other hånd, have many quite small warty 
papillæ on the marginal lobes but none on the central disc; they 
are most numerous in the smallest specimen. — It is relevant to all 
the specimens that proportionate to the size the tentacles are more 
numerous than in the typical C. arctica ; furthermore, in the three 
smallest specimens the middle tentacle in each bundle is much 
larger than the others.
