1 retain for this form the specific title Cavolinia globulosa, since the figure to 
which Gray refers in his Catalogue is that of Souleyet’s Atlas (Voyage de la Bonite), 
which appeared (without text) before the catalogue of Mbrch, and designates the species 
in question as “ Hyale globuleuse, Rang.” 
Habitat. — Indian Ocean; from 40 0' N. to 34° 30' S. (Boas), from the coast of 
Africa, Red Sea (Issel), Zanzibar, Natal (Pfeffer), to Australia. 
Pacific Ocean ; western portion, from 13° N. (“ Vettor Pisani” Expedition), China Sea 
(Boas), Malay Archipelago; eastern portion, from 2' N. to 12° S. (Knocker). 
Souleyet 1 and A. Adams 2 have cited this species as from the Atlantic, but without 
any precise information. Pfeffer 3 alone notes a single definite locality, lat. 1 S., 
long. 25 0 AV. I am inclined to suppose that this was some error in labelling, and that 
Cavolinia globulosa does not occur in the Atlantic. It is not recorded either by 
d’Orbigny, Benson, or Knocker ; and Boas, who has examined so much material from the 
Atlantic, does not note a single specimen as occurring there. And, finally, although 
the Challenger explored so much of the intertropical Atlantic, and traversed it several
