wings. It crawls about lazily on the cabbage, and lays its eggs 

 in the moisture between the leaves, about the heart of the 

 plant. 



Another fly {Ainalopteryx i/iarifi/iia), with wings rudimentary 

 but larger in proportion to the body than in the other, is found 

 about the rocks, on the sea shore, where it jumps about when 

 hunted, as if it were a small grasshopper. It is the same as 

 found at Marion Island, where it was discovered by Von 



KERGUELEN CABBAGE, PRINGLEA ANTISCORBUTICA.

Willemoes Suhm. Probably the fly frequenting the cabbage 

 exists also at Marion Island ; but we did not know where to 

 look for it when there, and cabbages were not very abundant ; 

 but it is possible, also, that this fly does not extend there, for 

 we saw no teal on Marion Island, though they exist in abun- 

 dance on the Crozets, and especially on Possession Island, 

 where, as we were told by the sealers, there is a lake full of 

 them. However, we examined but a very small tract of 

 Marion Island, and similar tracts are to be found in Kerguelen's 

 Land, with very few cabbages, and consequently without teal.
