340 EIGHTH PACIFIC SCIENCE CONGRESS 



Dr. Hardenberg: It is hard to study our plankton due to the great 



abundance of floating water organisms. 

 Dr. Johnson: The plankton is not worked out seasonally. It is not 



such in watery plankton. However, near the California Coast, in 



spring, there is a large volume of plankton. 



Drs. Yaichiro Okada and Shizuo Mawatari of Japan, in their paper 

 entitled "Distributional Provinces of Marine Bryozoa in the Indo-Pa- 

 cific Region", presented a preliminary report on the distribution of the 

 Indo-Pacific bryozoa, tracing geographical isolation and the oceano- 

 graphical factors responsible for the formation of Bryozoan Provinces 

 in the Indo-Pacific region. They recognize three subregions, the In- 

 dian, the Western Pacific and the Central and Eastern Pacific with eight 

 provinces: (1) Ethiopian and (2) Indian for the Indian Subregion, 

 (3) Malayan, (4) Chinese and (5) Papuan for the Western Pacific 

 Subregion, and (6) Hawaiian, (7) Polynesian and (8) Mexican for 

 the Central and Eastern Pacific Subregion. Discussion follows: 

 Mr. Domantay: In your study of Japanese Bryozoans have you come 



across species of Bowersbankiaf 

 Dr. Okada: Yes, there are four species found in Japan but these are 



not mentioned in this paper. 



"The Distribution of Polychaetes within the Indo-Pacific Region" 

 by Mr. G. A. Knox of the Canterbury University College, New Zealand, 

 is the first distributional survey of this group for the area. The poly- 

 chaetes inhabiting the shelves of 24 regions in the Indo-Pacific area 

 were dealt with. Description of the species in the text was supple- 

 mented by tables on the distribution and number of species found in 

 each of the 24 regions. Extensive tables are given, an analysis of which 

 points to recognition of the following faunal areas:— (I) Indian, with 

 possibly a separate Arabian Sea region, (2) Malayan, (3) PhiHppine, 

 including South China Sea, (4) Southern Japanese, (5) Northern Jap- 

 anese, (6) Hawaiian, (7) Tropical Pacific. This paper was read by 

 Mr. Powell. 



Dr. Leonard P. Schultz in his paper, "A New Apf)roach to the Dis- 

 tribution of Fishes in the Indo-West-Pacific Area" presented a grouping 

 of marine ecological habitats. It advanced the concept that the so- 

 called species as named by Zoogeographers are actually composed of two 

 or more species, subspecies or races, each more or less inhabiting sub- 

 faunal areas. He considered that too much reliance has been placed 

 upon check lists prepared by ichthyologists with only a local faunal 

 concept and that the nomenclature used often stressed greater differ- 

 ences between faunas actually occurs zoologically. He advocates com-
