P. L. KRAMP. 



was found in the surface water east of the Newfound- 

 land Bank (stat. 80), carried southwards by the Labrador 

 Current from the Davis Strait. Tiaropsis multicirrata, a 

 common medusa in the coastal waters of North America 

 and North Europe, was taken at St. Johns. Obelia sar- 

 gassi was found among floating sea-weed in the Sargasso 

 Sea, hatched from hydroids growing on the sea-weed. 

 Chromatonema rubriim, previously known from deep 

 water off the New England coast and from the Davis 

 Strait, was found at several stations south and east of the 

 Newfoundland Bank (stat. 70, 80, 81, 82, and 84), so that 

 this interesting species is now known to be distributed 

 throughout the north-western basin of the Atlantic. 



On the eastern slope of the Mid-Atlantic ridge (stat. 

 53, south-west of the Azores) one specimen of Oceania 

 armaia was found; this species is previously known from 

 the Mediterranean and the Cape Verde Islands, but has 

 not until now been found so far out in the Atlantic— 



In the East-Atlantic basin, outside the contour of 4000 m. 

 (stat. 90 and 92), only one species was found, viz. 77a- 

 ranna affinis n. sp. — In the Mediterranean, just inside the 

 strait of Gibraltar (stat. 19), two species were found: 

 Tiaranna rotunda, previously known from the Strait of 

 Gibraltar and from the North Sea (a single specimen 

 mentioned by Hartlaub 1913); and Pandaea conica, a 

 common Mediterranean species, found only once outside 

 the Mediterranean, viz. in the South Atlantic by the "Val- 

 divia" Expedition. — In the waters west of the British Isles 

 three common North Atlantic species were found: Leu- 

 ckartiara octona, Neoturris pileata, and Laodicea undu- 

 lata. The most interesting find, however, is Halopsis 

 ocellaia, of which 6 specimens were found west of the 

 British Isles (stat. 94, 97, 98, and 101); the species is 

 known from the east coast of North America but has 

 never been recorded from European waters.
