Article II.— THE AMPHIPODA COLLECTED BY THE UNITED 

 STATES FISHERIES STEAMER 'ALBATROSS' IN. 1911, 

 CHIEFLY IN THE GULF OF CALIFORNIA 1 



By Clarence R. Shoemaker 



While the collection of Amphipods procured on this cruise of the 

 'Albatross' is comparatively small, it has, nevertheless, been found to 

 contain a large percentage of new forms. As this is the first collection 

 of Amphipods to be worked up from this little-known region, it is not 

 surprising that many new forms should appear. Among the one hundred 

 and sixty-seven specimens of the collection, thirteen families, sixteen 

 genera, and sixteen species are represented. Three genera and eight 

 species are new to science. 



The genus Batea was described in 1865 by Fritz Muller from the 

 coast of Brazil, and it is now for the first time reported from the West 

 Coast of North America. The hyperiid genera Anchylomera, Symprone, 

 Lycsea, Platyscelus, Tetrathyrus, and Am.phithyrus also are new records 

 for the West Coast.
