Genus BYBLIS, Boeck, 1871. 
9. Byblis sp. 
I. Salomon Atoll, 75 fms. Two, immature: length 7°5 and 4 mm. 
The above could not be identified with any known species, but are too immature for 
description. Ant. 1 reaches to the middle of the 8rd joint of the peduncle of ant. 2, of 
which the 2nd and 8rd joints are subequal. The eyes are obscure. The telson is sub- 
quadrate, wider than long, narrowly divided one-fourth of its length, the truncate ends 
of the divisions spinulose. The hind margin of the 2nd joint of perzeopod 5 is rounded 
below. 
Genus UROTHOL, Dana, 1852. 
10. Vrothoé elegans, Bate. 
I. Providence, Plankton, z, surface, 8 or 9 males: length 4 mm. 
The rose-colour on the bodies is well preserved in formic aldehyde. 
Genus LEUCOTHOE, Leach, 1813. 
11. Leucothoé spinicarpa (Abildgaard). 
I. Praslin, weed: 4small. Amirante, 29fms.: Ismall. §S. de Malha, C1, 150 fms., 
in a Brachiopod: 1 2 ovigerous 13 mm. 
Il. Wasin, mud, 10 fms.: 7, 2 ovig. 7°5 mm. 
III. Suakim Harbour, sponges 2. Quay wall 1. Other Red Sea localities 5. 
12. Leucothoé hornelli, A. O. Walker. 
III. SS.‘ Fayoum.’ One: length 5:5 mm. 
18. Leucothoé stegoceras, A. O. Walker. 
III. Suez Bay. One: length 7 mm. 
Genus STENOTHOE, Dana, 1852. 
14, Stenothoé gallensis, A. O. Walker. 
I. Amirante I., dredged, E14, 36 fms. Four: ¢ 4mm., 2? 3 mm. 
If. Zanzibar: many. 
III. “From Barnacles I.” Five small ovigerous females: length 2-3 mm. 
SS. ‘Fayoum.’ Several small. 
By an unfortunate error in the Amphipoda of the ‘ Pearl Fisheries’ the 4th perzeopod 
in this species was described as the 8rd, which has the 2nd joint as narrow as in 
pereeopods 1 and 2. This is the more regrettable as it is perhaps the most important 
difference between this species and S. valida, Dana. 
The very small form “from Barnacles”’ possibly does not belong to this species, the 
female having a small tooth on the palmar margin near the dactylus as descrihed in 
S. valida; unfortunately there is no male.
