in his valuable paper "Die Schizopoden der Deutschen Siid- 

 polar Expedition 1901 — 1903" (1914) has questioned my deter- 

 mination of the specimen of that species partly figured by me. 



I. Mysidacea. 



Pseudomma Belgicae (H. J. H. in MS.) Holt & Tätt. 



Hansen, 1. c. p. 11. — In the locality an error is found, 

 viz. long. 56°53' W., instead of 56°37' W. 



Pseudomma armatum H. J. H. 



Hansen, 1. c. p. 12. — In the book quoted five local- 

 ities, all at South Georgia, are enumerated. In the new ma- 

 terial a single immature female, also from South Georgia, is 

 found, and the label has the following particulars: Cumber- 

 land Bay, South Fjord outside the glacier. Net from 150 to 

 O m., and according to the contents of the net it had touched 

 the bottom. Temp. l,4o°. May 31, 1902. 



Pseudomma Sarsii (Will.-Suhm in MS.) G. O. Särs. 



Hansen, 1. c. p. 13. — In 1913 I had only seen two spe- 

 cimens taken in different places at South Georgia. In the 

 additional material is found a third specimen secured at the 

 first-named of the localities, viz. lat. 54°15' S., long. 36''25' W. 

 South Georgia, 250 m. Clay. Bottom temp. 1°,2 April 22, 

 1902. This new specimen is an adult female, measuring 10,3 

 mm. in length, and it differs in a few particulars from the 

 figures and description of Särs. The serration on the margin 

 of the eye-plate is at the sides continued somewhat more 

 backwards than drawn by Särs. The distal outer tooth of 

 the antennal squama is much larger, both broader and longer, 

 than figured by Särs. Finally, the telson has, as figured by 

 Särs but in contrast to his description, only 4 (not 5) pairs 

 of terminal spines, as the most lateral fifth spine is wanting, 

 but on each lateral margin 9 or 10 spines are found, and
