BIGELOW: MEDUSAE AND SIPHONOPHORAE. 387 



Laodiceidae L. Agassiz. 

 {Sensu Brown, 1907). 



Laodicea Lesson, 1843. 

 (Sensn em. Browne, 1907; Bigelow 1909a). 



Laodicea cruciata (Forskal). 



Medusa cruciata Forsk&l, 1775, p. 110; 1776, taf. 33, fig. 8. 

 Laodicea cruciata L. Agassiz, 1862, p. 350. 



(For synonymy, see Mayer, 1910, p. 201). 



As Mayer points out, the identity of the Medusa cruciata Forskal 

 with Laodicea cruciata L. Agassiz and later authors (= Thaumantias 

 mediterranea Gengenbaur 1856, and Thaumantias undulafa Forbes and 

 Goodsir 1853), is doubtful. But at least there is nothing in Forskal's 

 figure to forbid it, and it will tend toward stability of nomenclature to 

 use L. cruciata, referring it, however, to Forskal, not to L. Agassiz. 



The Bache collection contains a single specimen of this common 

 and well-known species, which adds nothing to previous accounts. 



Station 10,206, surface, 1 specimen. 



Eucopidae Gegenbaur. 

 Aequorea aequorea (Forskal). 



Medusa aequorea Forsk&l, 1775, p. 110; 1776, pi. 32. 



(For synonymy, see Mayer, 1910, p. 325, and Bigelow, 1913, p. 38). 



Station 10,161, surface, 1 very fragmentary specimen, 60 mm. in 

 diameter. 



This specimen, undoubtedly an Aequorea, apparently belongs here, 

 but is too imperfect to add anything to previous accounts. 



TRACHOMEDUSAE. 



Trachynemidae Gegenbaur. 



Aglaura hemistoma Peron and Lesueur. 



Aglaura hemistoma Peron & Lesueur, 1809, p. 351. 



(For synonymy, see Bigelow, 1909a, p. 119, and Browne, 1916, p. 196).
