Nicella monUifm-me is recorded from oue hundred fathoms, and the only 

 other records from over fifty fathoms are Scirpearia thomsoni and Scii-pearia 

 alba, both from 88 fathoms. The following table will give at a glance the 

 chief records for each of the species in this report : —

It is quite probable, however, that when more inshore-work is carried 

 on in tropical seas records will be abundant from water of much less 

 depth than that at present given. Eidley in referring to the depths at 

 which Juncclla gemmacea occure gives " between tide marks," and, as has 

 been already pointed out in the " Biological Note," it is no uncommon 

 occurrence on the scattered coral reefs of the Mergui Archipelago to see at 

 low spring tide huge colonies of J. gcmmacca and J. juncca as well as 

 Melitodcs and other Alcyonaria swaying to and fro in the aii'.
