must be added that in specimens with the first pair of legs enormously 

 elongate and thickened the legs of the second pair are in all respects 

 similar to those shown in figures 2 a and 26. Stages between those 

 shown in figures 26 and 2d have been omitted as unnecessary. 



Distribution. — In the Ingolf Malacostraca (vol. 1, 1908) I had put 

 together our knowledge of the distribution of Bhoda inermis and 

 Thysanoessa neglecta; in Gr0nlands Krebsdyr og Pycnogonider (1913) 

 K. Stephensen has added several statements. A brief abstract may 

 be given here. It is known from the Gulf of St. Lawrence and was 

 taken in a line between southeastern Newfoundland and Cape Fare- 

 well. Along west Greenland it goes northward to lat. 70 J ° N., at east 

 Greenland northward to lat. 78° 13^' N. Furthermore, it is known 

 from Iceland, the Faroes, Scotland, the western end of the Channel, 

 the North Sea, Skager Rak, and northern Kattegat. It is extremely 

 common on the northern coast of Norway and has been caught at 

 Spitsbergen, in the Kara Sea, and at Franz Joseph Land. The list 

 of localities above gives our information on its occurrence in the 

 North Pacific and Bering Sea.
