the dredge), still the following records, if few, tend 

 to show that although a good deal has alreadj' 

 been done towards working out the marine fauna 

 of these islands, yet a judicious use of the dredge 

 will still yield results sufficient to reward the pains- 

 taking investigator. The species observed by nie 

 that do not seem to have been previously recorded
