WALKER—AMPHIPODA GAMMARIDBEA. 341 
Easily recognizable by the peculiar structure of uropod 3, which, under a low power, 
appears to be uniramous, hence the specific name; also by the powerful gnathopod 2 in 
the female. In the former character this species approaches the genus Photis and will 
not fit into the Synopsis of the Photide (Tierreich, Amph. Gam. p. 603), but its well- 
developed accessory flagellum and general form are nearer to Hurystheus. E. hirsutus, 
Giles, appears to be very near this species, but there is no mention of the inequality of 
the rami of uropod 3 in that author’s description.

II. Wasin, mud, 10 fms. Two: length 3 mm. 
The above agree with Della Valle’s figures, except that the anterior angle of side plate 
is less produced and the last 2 pairs of perzeopods are stouter than figured. In both 
these points the specimens resemble those taken at Port Erin, I. of Man. 
I still hold by the opinion given in 1895 (4 swpra) and shared by Mons. Chevreux 
(5 supra) that L. pectinatus, Norman, is identical with Z. pilosus, Zadd.; nor can I find 
sufficient justification in the prolongation of the anterior angle of side plate 1 for 
making a separate species (LZ. della vallei, Stebb.) of the form described and figured by 
Della Valle as Z. pilosus. In the Wasin and I. of Man forms the angle of the side plate 
appears to be about 45°. 
Genus CHEV ALIA, A. O. Walker, 1904. 
42. Chevalia aviculae, A. O. Walker. 
I. S. de Malha, C16, 26 fms. One male: length 65 mm. Cargados, B 25, 
22 fms. Two. 
The male specimen differs from those from Ceylon in having the wrist in gnathopod 
2 shorter in proportion to the hand and the front margin less rounded, As it is larger 
it may be an older male than the Cinghalese examples. 
Genus 4MPHITHOE, Leach, 1813. 
43. Amphithoé intermedia, A. O. Walker. 
I. Praslin reef. One. 
II. Zanzibar. Several. 
TII. Suez: several. Khor Dongola: six. 
Length of female with ova 8 mm.
