Family GAMMA RID^. 



Gammaridce (part), Leach, Edin. Encycl., vii., 1814, p. 432. 

 Gammaridce, Stebbing, Das Tierreich, xxi., 1906, pp. 364, 729, 

 Gammaridce, Chevreux, Mem. Soc. Zool. Fr., xx., 1908, p. 478. 

 Gammaridce, Chevreux, Trav. Soc. Imp. St. Petersbourg, xxxvii., 

 pt. 2, 1908, p. 91. 



To the very numerous genera of this extensive family, defined 

 or mentioned in " Das Tierreich," Chevreux added in 1908 the 

 genus Issykogammarus, and in 1909 the genus Metacrangonyx. 



Genus M E L I T A, Leach. 



Melita, Leach, Edin. Encycl., vii., 1813, p. 403.

 Melita, Chevr-eux, Bull. Inst. Oc6anogr. Monaco, JSTo. 122, 1908, 

 p. 6. 



To the twelve species of this genus described in " Das 

 Tierreich" must be added three species there named, but not 

 described, M. richardi, Chevreux, 1900, M. parvimana, Holmes,. 



1903, M. zeylanica, Stebbing, 1904. M. tenuicornis, Walker, 



1904, reinstates Dana's earlier name for it, M. inaequistylis, 

 which was left among uucertain species in " Das Tierreich." 

 Melita grandimana was added to the genus by Chevreux in 1908, 



MELITA FRESNELII {Audouin).

The enormously developed hand of the second gnathopod in 

 the male of this species seems to be very characteristic. It 

 would probably be ve'y inconvenient for the animal to have both 

 members of the pair equally enlarged, but see note on Maera 

 inaequipes, p. 599. 



Localities. — Ofi" Manning River; Botany Bay, 50-52 fathoms; 

 a single specimen of the male.
