98 K. MITSUKIRI : STUDIES ON 



variation in the widtla of the rods, and some of the broad ones 

 approach tlioso of this variety figured by Ludwig. 



There can bo no doubt that //. kapiolanice Bell from the 

 Sandwich Is. ought to be placed in //. luhrica. Whether it be- 

 longs to one of the above varieties, or constitutes a distinct va- 

 riety, I have no means of ascertaining. 



H. icilleiji Bedford from Blanche Bay, New Britain, described 

 from two specimens respectively 2.2 cm. and 1 .7 cm. in length, 

 is undoubtedly the young of some form belonging to this species. 

 Like the young animals I have studied (see above), they had 

 granulated rods (up to 0.125 mm.), smooth rods (up to 0.1 mm.) 

 and a few scattered tables with reduced spire, but lacked the H- 

 shaped supporting rods. 



It will be seen from the above list of localities that each 

 variety, as a matter of general fact, has its own region of 

 distribution. There are probably two reasons for this : 1) these 

 varieties are more or less local as I have stated above, and 2) 

 the determination by each investigator has been more or less 

 influenced by the identification of previous authors.
