It seems, however, most probable that these old plants are 

 no longer in existence. At my request Mr. A. D. COTTOX has most 

 kindly made a search in the Kew Herbarium without success and 

 furthermore he writes to me that Mr. A. GEPP tells him that 

 none of ELLIS and SOLANDER'S types are in the British Museum 

 and that he together with Mrs. GEPP had been to the Royal 

 College of Surgeons, where the collection of ELLIS and SOLANDER 

 was supposed to have been preserved and had made a personal 

 search also without success. But of course this negative result is 

 also of interest; had the species of ELLIS and SOLANDER existed 

 an examination of these would certainly have resulted in several 

 of the specific names of KJELLMAN being changed. 



By the fact that LIEBMAN and 0RSTED have sent ARESCHOUG 

 material of many of the algae which they have collected in the 

 West Indies, KJELLMAN has had relatively rich material from 

 this region and several of his species are based upon specimens 

 from the Danish Islands. During the determination of my col- 

 lection it has been of great help to me to have had on loan all 

 the material of Galaxaura determined by KJELLMAX. 



In the following survey 11 species are mentioned belonging 

 to the following 5 of KJELLMAN'S 9 groups, namely: 



Sectio I. Rhodura Kjellm. 



A. with long assimilating filaments . . . . 1. G. comans Kjellm. 



B. with long and short assimilating filaments. 



I. assimilating filaments often clearly arranged in belts 



2. G. subrerticillata Kjellm. 



II. assimilating filaments evenly distributed over the 

 whole surface. 



a. thallus with long internodes, flagellate 



3. G. flagelliformis Kjellm. 



b. thallus with shorter internodes 



1. large, much ramified tufts, thallus flexible, densely 

 covered with long hairs . 4. G. lapidescens (Sol.) Lamx. 



2. low tufts, thallus fragile, rugose. 5. G. delabida Kjellm. 



Sectio II. Microthoe Dcsne, J. Ag. 



a. thallus quite or nearly glabrous, annularly constricted 

 internodes of nearly the same length 



6. G. rugosa (Solander) Lamx. 



b. the assimilating filaments more persistent, less annularly 

 constricted internodes of variable length. 7. G. squalida Kjellm.
