ANOTHER NEW CHAETOGNATH FROM MALAY WATERS, WITH A PROPOSAL OF GROUPING SOME SPECIES OF SAGITTA INTO SUBGENERA

Abstract

After we had submitted our manuscript on a new chaetognath, Sagitta johorensis, from Malay waters to the .editorial board of the Publ. Seto Mar. Biol. Lab., another new form was discovered in the material from Penang waters. This belongs to the neglecta-group, too, but it is very distinctive in having the posterior fin beginning at the trunk-tail septum. As so many species are now included in the neglecta-group, we have become aware of the necessity of subdividing the genus Sagitta or grouping some species of Sagitta into subgenera as mentioned in the paragraph of remarks. Before closing the introductory note, we want to express here our hearty thanks to the Director of Fisheries, Federation of Malaya, for his kindness in giving us the chance to study the material and to publish the results obtained.
