OcciTREENCE. — This was found abundantly at La Jolla, California, in hauls 

 made from June 27 to July 17, 190fi, from near shore to 7 miles offshore and 

 from the surface as well as in hauls from depths up to 595 meters, in surface 

 temj^eratures varying from 20°4 C to 21 ?4 C. There is no evidence that it 

 lives in such depths. In July, 1914, and also in July and August, 1915, it was 

 observed in the surface hauls made near shore, though not a])undant in either 

 year. In 1917 it was present in the majority of the hauls made between June 

 26 and August 22, both in the surface hauls made at the end of the pier and at 

 the Biological Station and in the deeper hauls made from 1 to 11 miles otfshore 

 from depths up to 80 meters. 



Synonymy. — This was figured by Kofoid (1907&) as P. schwartzi. Chatton 

 (1914c) separated it from that species and gave to it specific rank as P. kofoidi.
