26 NEW INVEUTEBRATA FROM 



daring my stay at Santa Barl)aia and Monterey, they were 

 rare and were seldom seen. 



AuRELiA LABI ATA Cham, et Eys. 



(PLATE V, FIG. 2.) 



The Pacific Anrelia is readily .distingnished from the At- 

 lantic species, found from Greenland to Newport, by the 

 pinkish color of the umbrella, while the specimens which 

 Avere found are much smaller than those of A. flavid- 

 f la. The largest specimen seen Avas about sixteen inches 

 in diameter. I am, however, told b}^ fishermen that in the 

 summer months much larger s[)ecimens occur. There is 

 no doubt that the species is a characteristic one, but 

 Avith the exception of the above ditlerences and a few oth- 

 ers, it closely resembles our conmion eastern species. The 

 eye spots appear browner than those of Jiavidula 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 oi'Jlavidida 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 foinid to be in- 

 fested by a Hjperia, as is also the case with A. Jiavidula. 



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. jjano- 

 •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 denliculata and Jlaveola are very short.
