570 " THETIS " SCIENTIFIC RESULTS. 



Glycerina affinis, Chilton, Proc. Linn. Soc. N.S. Wales, ix., 1885, 

 j). 1036, pi. xlvii., fig. 1, a, b. 



Amaryllis macrophihalmus, Chilton, Trans. N. Zealand Inst., 



xxxviii., 1906, p. 267. 

 Amaryllis macrophthalma, Stebbing, Das Tierreich, xxi., 1906, 



p. 24. 

 Amaryllis macrophthaima, A. 0. Walker, Trans. Linn. Soc, 



xii., 1909, part 4, p. 327. 



In 1904, Mr. A. 0. Walker distinguished a genus Vijaya from 

 Amaryllis by the character that it has the upper antennae in the 

 male with the first joint of the flagellum much longer than any 

 of the succeeding joints and very setose. He remarks that " the 

 curious difference in the male and female antennae makes a new- 

 genus necessary." This called my attention to the desirability of 

 examining a male specimen of Amaryllis macrophthaima, and the 

 " Thetis " collection has furnished the opportunity. It proves 

 that the difference in question occurs between the sexes of that 

 species, so that the necessity for Vijaya is discharged. Amaryllis 

 tenuij)es (Walker), however, remains specifically distinct, since, 

 unlike any other species of the genus, it has the anterior angle of 

 the fourth side-plate of the peraeon acutely produced forward. 



Localities. — Off Manning River ; off Port Hacking ; Botany 

 Bay, 50 to 52 fathoms ; off Coogee ; off Wata Mooli, 54 to 59 

 fathoms. Mr. A. 0. Walker notes its occurrence at Wasin, 

 British East Africa, taken at a depth of 10 fathoms. It appeals 

 to be an abundant Australian species. 



Genus WALDECKIA, Chevreux. 



Charcotia, Chevreux, Bull. Soc. Zool. Fr., xxx., 1905, p. 16'^ 



Charcotia, Walker, Ann. Mag. Nat. Hist., (7), xvii., 1906, p. 454. 



Charcotia, Stebbing, Das Tierreich, xxi., 1906, p. 718. 



Waldeckia, Chevreux, Exp. Antarct. Frangaise, Amphip., 1905, 

 p. 13. 



Waldeckia, Walker, Nat. Antarct. Exp., iii., 1907, Amphipoda, 

 p. 10. 



M. Chevreux, finding that the name Charcotia was pre- 

 occupied, adopted in place of it Waldeckia, in compliment to 

 Mme. Waldeck- Rousseau, Dr. Jean Charcot's sister. At the 

 same time he distinguished the generic characters from those of 

 the typical species, W. obesa, as follows : — 



Body extremely obese, integument thick and hard. Side- 

 plates remarkably deep, those of the fifth pair not bilobed.
