meleagris and fritillaria may ... be allowed to stand, at least provisionally ". On 

 the other hand, Ranson (1949, pp. 150-154) through a careful examination of speci- 

 mens from French Guiana and others from the Gulf of California and Ecuador, 

 once more separated the two forms, pointing out several distinguishing features, 

 especially that in Jritillaria the scapulets are " plus profondement situees dans la 

 sous-ombrelle ". 



This latter feature, which was emphasized by Mayer as well as by Haeckel himself, 

 is very distinct in all the original specimens and really seems to be characteristic of 

 fritillaria. On the other hand, I can see no indication of the median incurvations of 

 the umbrella margin between the rhopalia, described and figured by Haeckel. It 

 is difficult to state the exact number of marginal lappets in the original specimens, 

 but as far as I can see, the number of velar lappets does not exceed 12 or 16 in each 

 octant; each lappet is, however, divided into two by a short median line; this was 

 also observed by Ranson in the specimens from Trinidad examined by him 



The specimen labelled 43° N. 61° 30' W. is particularly well preserved and about 

 60 mm in diameter. One of the three specimens from Surinam is about 50 mm wide 

 and rather badly preserved; another of these specimens is about 80 mm wide and 

 somewhat torn. The largest specimen, from which presumably Haeckel's figure of 

 the entire medusa was drawn, and which may be designated as the type, has been cut 

 into several pieces. 



It seems to me that the differences between S. fritillaria and meleagris are so slight 

 that they do not justify a distinction of two separate species, but sufficient to regard 

 fritillaria as a distinct variety of meleagris ; so I am inclined to adhere to the views of 

 Mayer and Bigelow. 



Stomolophus agaricus Haeckel. 



1880, p. 597. 



[Stomolophus meleagris L. Agassiz.] 



(199) Punta Arenas, Pacific coast of Costa Rica, Central America; ORSTed, 



1843. 1 specimen. 

 According to Stiasny (1922 a, p. 553), who has examined the specimen, it may be 

 regarded as belonging to S. meleagris L. Agassiz, as already presumed by Mayer 

 (1910, p. 710). 



Versura palmata Haeckel. 

 1880, p. 606, PI. XL, figs. 9-12. 

 [Mastigias ocellata (Modeer).] 

 (186) Cheribon, north coast of Java; Andrea, 1870. 1 specimen. 

 By a careful examination of the present type-specimen Stiasny (1922 a, p. 538) 

 referred it to Mastigias ocellata (Modeer). 



Cotylorhiza tuberculata (Macri). 

 1880, p. 610. 



(200) Trieste, Adriatic Sea; Steenstrup. 1 specimen. Correctly identified. 



Cotylorhizal {Stylorhizal). 

 [Mastigias ocellata (Modeer).] 

 (194) 1° N. 104° E., near Singapore; Strandgaard. 1 specimen. 

 Stiasny (1922 a, p. 530) has identified this specimen as Mastigias ocellata (Modeer).
