his paper "to direct attention to the subject in the hope that zoologists 

 who are dealing with plankton will not confine their attention merely 

 to the adult groups of the same, but will, in addition, arrange for ex- 

 amination of the larvae therein in view of the distribution of the different 

 groups of littoral animals." I would only express my astonishment at 

 the conclusion he arrives at, viz. that "it would appear to me (Gardiner) 

 that no results in distribution can be expected, so far as the Indo-Pacific 

 is concerned, from Echinoderms and probably also from Enteropneusts 

 - other than the Crinoids," the pelagic life of which latter is consider- 

 ably shorter than that of typical pelagic Echinoderm larvae. Probably 

 this statement is not meant so absolutely as it sounds. I also venture 

 to think that the fear expressed by Stanley Gardiner "that in the 

 present state of our knowledge any consideration of larval distribution 

 is premature and must be inconclusive" has been partly removed by 

 the present researches.
