the western spiny lobster in 1918, procured additional specimens 

 from the same locality. 



Bated is apparently a littoral genus and occurs at depths from 2 

 to 45 fathoms. This genus will probably be found to inhabit the 

 entire tropical and temperate coasts of the Western Hemisphere. 

 Comparatively few amphipods have been collected in these regions, 

 but in almost every instance where systematic investigation has been 

 carried on, this supposedly rare genus has been brought to light. 



The Albatross in 1885 dredged from two localities off the west 

 coast of Florida specimens of the family Bateidae which, on ac- 

 count of their prominent dorsal teeth, I have put into a new genus, 

 Carinohatea. While at the Virgin Islands during the summer of 

 1915 I collected additional specimens of this new genus at several 

 localities about the Island of St. Thomas. 



To the present time members of this family have appeared in the 

 waters of the Western Hemisphere only. 



Family BATEIDAE Stebbing 



The family as characterized by Stebbing in 1906 in " Das Tier- 

 reich " Amphipoda (p. 355) is as follows: Head strongly rostrate. 

 Side-plate 1 rudimentary. Antenna 1 without accessory flagellum. 

 Mandible with palp. Gnathopod 1 degraded, without hand. Telson 

 cleft. 



Genus BATEA 



1865. Batea Fritz Mullee, Ann Mag. Nat. Hist., ser. 3. vol. 15, p. 276. 



Body not dentate. Side-plate 4 rather large and deeply excavate 

 behind. Antenna 1 little shorter than antenna 2. Maxillipeds, outer 

 plates not quite reaching apex of second joint of palp, and fringed 

 with spine-teeth on inner margin. Gnathopod 1 degraded, ending 

 with a feeble linear second joint, which is slightly longer in female 

 than in male. Gnathopod 2 subchelate. Peraeopods 3-5, second 

 joint expanded. Uropod 2 shorter than uropod 1 or 3; uropod 3,
