98 E. MITSUKUEI : STUDIES OX 



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

 approach tliose of this variety figured by Ludwig. 



There can be no doubt that H. kapiolanîœ Bell fi'om the 

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

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

 riety, I have no means of ascertaining. 



H. icilleyi Bedfoed 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- 

 sliaped supporting rods. 



It will be seen from the above Kst 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 identitication of previous authors.
