to be reached from our colonies, are very little known 

 and specially hère, where the great currents join the sea, 

 interesting things will probably be found. This small 

 collection, which, owing to the carelessness of the crew 

 is merely a portion of the whole, consits of full 60 diffé- 

 rent species, of which 5 are not included in Murray's 

 list. I woiild doubtless hâve been able to extend the list, 

 if ail spécimens had been complète and in perfect condition. 

 With the aid of material, which may come into my hands 

 later on, I hope to be able to do so. ') 



As the local names are very characteristic, when one 

 knows the plants, I thought it would not be without 

 interest to give a short list of them. A différence is often 

 made between two species of one genus, whilst two 

 forms so différent in dimension as Haliseris delicatula and 

 Haliseris Justii go under one name. Also Âcetabularia 

 caraïbica and Gracilaria lichendides, two gênera not like 

 each other at ail hâve the same local name. 



Before closing hère I wish to thank Mrs. Web er — van 

 Bosse, under whose direction I made this list, for her 

 good advice and her ready help, as well as for the 

 indispensable use of her extensive collections and library.
