Plate i 



1. Neomeris duinetosa. Photograph of probahly authentic specimens now pre- 

 served in the herbarium of the Museum d' Histoire Naturelle of Paris. 



2. Neomeris annulata. Photograph of fluid-nreserved specimens from Bermuda 

 {Howe J2o). 



3. Neovieris stipitata. Photograph of fluid- preserved type specimens from Singa- 

 pore {Ridley'). 



4. Neomeris van Bosseae. Photograph of fluid-preserved type specimens from 

 Sikka, Flores, Dutch East Indies {A. Weber-van Basse iigd). 



5. Neomeris 7nucosa. Photograph of fluid-preserved type specimens from Atwood 

 (Samana) Cay, Bahamas {^Howe jjo8). 



6. N'eomeris Cokeri. Photograph of fluid-preserved specimens. The four large 

 plants to the left (New Providence, Bahamas, Howe 30"/^) represent an unusually 

 large condition of the species (see Bull. Torrey Club 32 : 580. 1905). The remain- 

 ing specimens (Atwood Cay, Bahamas, Howe ^^og) are of the normal form and size. 



7. Neovieris va)i Bosseae. Photograph of dried specimens in the Museum d' His- 

 toire Naturelle of Paris, collected by W. H. Harvey in the Friendly Islands and 

 distributed by him as Neomeris dumetosa. 



The photographs all represent the plants in their natural size. 



Plate 2. Udotea conglutinata 

 The largest plant (fluid -preserved) is from Bemini Harbor, Bahamas {Hoive 32400); 

 the smallest (dried), at the upper right-hand corner, is from Castle Island, Bahamas 

 ( Ho2ve ^J4ia); the remaining (dried) are from Watling Island, Bahamas [Howejsjy); 

 all are of the natural size. 



Plate 3. Udotea cyathiformis 



1. The more or less Penicillus-Wkt (fluid-preserved) plants photographed in the 

 three upper rows are from Cockburn Harbor, South Caicos {Howe Sj47)- Natural 

 size. 



2. The five or six (fluid-preserved) plants of the lowest row ( Bemini Harbor, 

 Bahamas, Howe 3240b) represent the typical form of the species. The middle plant is 

 almost perfectly cyathiform, with, however, a slit down one side of the cup-like flabel- 

 lum ; the plant at the extreme left has a merely concavo-convex or slightly spoon-shaped 

 flabellum and approaches in form certain conditions of U. conglutinata. Natural size. 



Plate 4 



J. Halimeda lacrimosa. The three larger plants at the left of the photograph, the 

 type specimens, are from the island of Mariguana, Bahamas {Howe £^24), where they 

 were dredged in 3 or 4 m. of water; the small plant at the right is from 10 to 20 m. of 

 water on Great Ragged Island, Bahamas {Hozue j8io). Natural size. 



2. Udotea spimdosa. Photograph of type specimens (dried) from Bemini Harbor, 

 Bahamas {Ho'iue 3272). Natural size. 



Plate 5 

 I-14. N^eomeris mucosa 



1. A young stage, with the first four whorls of primary branches. 



2. Two members of the fourth whorl of plant shown in Figure i, showing trimerous 

 branches of the second order.
