of the species in the Pacific as far south as Monterey Bay, California. 

 That may be the southern limit because in the time since my (1954a) 

 paper I have examined more than 600 samples and tens of thousands 

 of specimens of Ampelisca from southern California, 200 miles south 

 of Monterey, and have never found a specimen of A. eschrichtii (paper 

 in preparation). Samples extended from depths of 4 to 1500 m. 



There can be no confusion of A. eschrichtii with the southern 

 Californian A. indentata which has a similar head, because the latter 

 has a large lobe on article 4 of pereopod 5, a stroogly saddle-shaped 

 dorsal carina on urosomite 4 and virtually no tooth on pleonal epimeron 

 3, all in contradistinction to A. eschrichtii.
