In addition to the twelve species of this genus described in 

 " Das Tierreich," three are named in the appendix, M. dubia, 

 Caiman, 1898; 31. hirondellei, Chevreux, 1900; M\ othonides, 

 Walker, 1904. To these should be added M. prionochira, 

 V. d. Briiggen, 1907; M. spitiicauda, Holmes, 1908; M. rath- 

 bunce, Pearse, 1908.

The specimens which I assign to this species do not justify the 

 specific name, inasmuch as the second pair of gnatliopods appear 

 to be, as a rule, quite alike in size and sculpture. They are very 

 large and have the deep central notch in the broad, almost trans- 

 verse palm, which suggested Costa's later name Gammarus 

 scissimanus, supposed to be a different species. In the specimen 

 from off Coogee the first antennte have a primary flagellum of 

 twenty-nine joints, a secondary of ten ; in the second antennte 

 the flagellum is eleven-jointed. In one of the specimens from off 

 Wollongong the Bame numbers were counted, but one of the 

 upper antennae had an eight-jointed accessory flagellum, the 

 other a ten-jointed. Lenth of specimen 9 mm, Walker's speci- 

 men measured 5 mm. 



There is a strange resemblance in the second gnathoj)ods <>i 

 this species to those of the female Elasmopoides chevren.ri, from
