STEAMER ALBATROSS ON THE 



COAST OF CALIFORNIA DURING 



THE SUMMER OF 1904=^ 



BY 



Wm. e. eittee. 



The work of the Albatross from ]\Iarch 1 to June 11, 1904, f ar- 

 iiished material for the only bit of information we have concern- 

 ing the off-shore ascidians of the California region. No shore col- 

 lections are included in this report. It should be stated, however, 

 that many of the dredging stations, probably more than half, and 

 particularly those in and about Monterey Bay, were in depths of 

 only a few fathoms — 100 or less. 



The following systematic table of the fourteen species in the 

 collection shows the depths and also the geographic position with 

 reference to Point Conception, from which the species come. Full 

 data as to habitat, so far as the field records furnish them, are 

 given under each species. 



Family Molgulidae — depth. LocALrry.
