TRACHYMEDUSAE 53 



Distribution. Rhopalonema velatnm is widely distributed and very common in the warm parts of 

 all the oceans, including the Mediterranean. Its southern limit of distribution is approximately 

 about 45° S in the Atlantic and Indian Oceans, and about 30° S in the Pacific. In the Atlantic it may 

 occasionally penetrate as far north as off the west coast of Scotland, and it is recorded from the Gulf 

 of Maine on the American coast. It belongs mainly to the upper layers, but may also be met with 

 at considerable depths.

Most of the localities are off the west coast of Africa, between about 20° N and 34° S. St. 1056 is 

 north of South Georgia. Some of the specimens are in fairly good condition. The specimens vary in 

 diameter between 9 and 18 mm. Thiel (1936, p. 10) takes it for granted that this species is identical 

 with R. velatnm, but as demonstrated by me in a previous paper (Kramp 1947, p. 14) it diflFers from 

 that species in several regards. 



Distribution. This species is widely distributed in the deep layers of all the oceans, but it seems to 

 be fairly rare. In the Pacific and Indian Oceans it has only been found in tropical waters, in the Atlantic 

 it occurs as far north as west of Scotland and in the Gulf of Maine. It has frequently been recorded 

 from the tropical Atlantic. The occurrence at St. 1056 is considerably farther south than has been known 

 up to now (text-fig. 19, p. 103). It belongs to the deep and intermediate layers, but may occasionally 

 be found at higher levels.
