Hy 

 C. Eliot, 



Vice-Chaucellor ol' the University of Sheffield. 



With Plates XI and XII. 



The following notes are the result partly of an examination of various 

 living specimens at Plymouth in the spring of 1905, and partly of the 

 study of preserved material most kindly placed at my disposal by 

 Mr. E. J. Allen and Mr. W. I. Beaumont, of the Laboratory, Plymouth, 

 Mr. W. E. Hoyle, of the Manchester University Museum, and the 

 Council of the Hancock Museum at Newcastle. I must also express 

 my thanks and obligations to Mr. T. J. Evans, lecturer in Biology at the 

 University of Sheffield, who has prepared for me sections of the smaller 

 specimens and embodied the results in drawings which will add very 

 materially to any value which this paper may have.
