MEDUS.E OF THE WORLD. 



GENERIC CHARACTERS. 



Thaumantiadae with 4 principal radial-canals which branch, and the branches again 

 branch, and all unite with the circular vessel. The gonads are developed upon the outermost 

 branches of the radial-canals near the ring-canal. Tentacles numerous. There may or may 

 not be marginal clubs or cirri. Development unknown. 



Modern authors have commonly followed Peron and Lesueur, 1809, and Eschscholtz, 

 1829, in calling this genus Berenice, but if we follow the rule of precedence the name Cuviena 

 must stand. It is rarelv a pleasant duty to revive an unfamiliar name to supplant one well 



known to literature, but happily in this case the 

 name of one whose memory we all delight to honor 

 may once more be associated with a genus in that 

 branch of science which his labors ably advanced.

(?) Berenice capillata, HAECKEL, 1879. Syst. der Medusen, p. 154, 

 taf. 9, fig. 5. 



According to Peron, bell is flat and shield- 

 shaped, about 50 mm. wide and 10 mm. high. 

 There are 50 to 60 very long thin tentacles with 

 very large, hemispherical basal bulbs. Each of the 

 4 principal radial-canals gives rise to two opposed 

 side branches, and these side branches as well as 

 the principal canals give rise to 3 to 5 terminal 

 branches which reach the circular canal. Thus 50 

 to 60 canals reach the circular vessel. The 50 to 60 

 gonads are developed on terminal branches of 

 canals. Bell, gonads, and tentacles rose-red, and 

 tentacle-bulbs yellow. This species is found in the 

 tropical Atlantic. 



I am inclined to regard Haeckel's Berenice 

 capillatij as being identical with this medusa. 

 According to Haeckel the bell in B. " capillala" is 

 hemispherical, 20 mm. wide, 100 to 120 long ten- 

 tacles, with well-developed globular, spindle-shaped 

 basal bulbs. There are no marginal clubs or cirri. 



The 4 main radial-canals and their 2 side 

 branches each and all give rise to 4 to 8 terminal 

 branches, so that 50 to 100 vessels reach the 

 marginal ring-canal. Small, spindle-shaped gonads 

 are developed upon the terminal branches of the radial-canals near the ring-canal. Stomach 

 small, with 4 simple, recurved lips. Color (?) 

 Cape Verde Islands, Atlantic Ocean. 



Cuvieria huxleyi. 



Berenice huxleyi, HAECKEL, 1879, Syst. der Medusen, p. 154, taf. 9, fig. 4. 



Bell flat, 16 mm. wide, 0.4 mm. high. 16 long tentacles with globular to spindle-shaped 

 basal bulbs with ocelli. 80 to 100 marginal clubs, 2 to 6 between each successive pair of ten- 

 tacles. Stomach small, flat, with 4 simple, short, cruciform lips. The 4 main radial-canals
