122 NEW INVERTEBRATA FROM 



during my stay at Santa Barbara and Monterey, they were 

 rare and were seldom seen. 



AURELIA LABIATA Cham, et Eys. 



(PLATE V, FIG. 2.) 



The Pacific Aurelia is readily distinguished from the At- 

 lantic species, found from Greenland to Newport, by the 

 pinkish color of the umbrella, while the specimens which 

 were found are much smaller than those ot A. flavid- 

 nta. The largest specimen seen was about sixteen inches 

 in diameter. I am, however, told by fishermen that in the 

 summer months much larger specimens occur. There is 

 no doubt that the species is a characteristic one, but 

 with the exception of the above differences and a few oth- 

 ers, it closely resembles our common eastern species. The 

 eye spots appear browner than those of flavidula and the 

 pyramidal extension of the bell in the stomach is not so 

 marked. This latter character may, however, be a con- 

 sequence of the diminutive size of the specimen, for in the 

 young ofjlavidula this structure is wholly wanting. 



I found several specimens of Aurelia in the Bay of Mon- 

 terey and one near Point Conception. 



Several of the former specimens were found to be in- 

 fested by a Hyperia, as is also the case with A. flavidula. 



PELAGIA PANOPYRA Per. et Les. 



(PLATE V, FIG. 1.) 



The common large Pelagia from southern California 

 (Santa Barbara) is supposed to be the same as P. pano- 

 pyra. The other species of Pacific Pelagias, which have 

 been described, are P. denticulala Brandt, and P. flaveola 

 Esch. From both of these it differs in this, that while the 

 mouth arms of both denticulata and flaveola are very short,
