86 DISCOVERY REPORTS 



Note. The above remarks were printed before Augener's paper on the plankton of 

 the Weddell Sea reached me. Augener (1929, p. 303 ff.) claims that T. corpenteri and 

 T. planktonis are distinct species, both with representatives in Antarctic waters, and on 

 p. 306 summarises what he believes to be the distinguishing characters. I cannot here 

 discuss Augener's conclusions, but if he be followed, the examples of T. planktonis in 

 the present collection are those from the following stations: — MS 11, 19, 22, 25, 31, 

 32, 34 A, 62 and SS 21 . It is noteworthy that these are all coastal stations.

Remarks. As Malaquin and Carin (1922, p. 39) have already noted, there is no 

 means of distinguishing between T. eschscholtzi and T. septentrionalis except the 

 presence in the latter species of very indistinct hyaline glands in the ventral pinna. 



In the present collection, among the examples from a single haul, it frequently 

 happens that some can be shown after careful preparation to have indistinct hyaline 

 glands and others cannot. Moreover, in a considerable number the state of fixation is
