THE ALGAE OF BERMUDA. L03 



Family GELIDIACEAE. 



Wrangella Agardh.

 Rein; Kemp; Merriman, No. 5; Harris Bay, Jan., Castle Harbor, 



March, Tucker's Town, May, Harrington Sound near Flatts Brii - 

 Dec, Hervey; Shelly Hay, washed ashore, Hungry Bay, Nov., young 

 plants only; dredged in 18 m. Nov., Collins. Abundant and luxuriant 

 near Flatts Bridge from Dec. to Feb., seldom seen during the summer 

 months. 



Naccaria Endlicher. 



N. corymbosa J. G. Agardh, 1S99, p. 109; P. B.-A., Xo. 2036. 

 Cooper's Island, Feb., Farlow; Buildings Bay, April, Hervey. Bornet, 

 1892, p. 266, incidentally refers to Farlow's specimens as N. Wigghii; 

 comparison with the type specimen of N. corymbosa from Key \Y 

 in Agardh's herbarium, shows that the Bermuda plant is the same. 

 Whether the differences between the American and the European 

 plant are specific may require further study. 



Gelidium Lamouroux. 



1. Basal layer well developed; erect shoots seldom over 2 cm. high. 



4. G. pusillum. 



1. Basal layer scanty or wanting; erect shoots 5-50 cm. high. 2. 



2. Frond compressed or flat throughout, pinnate. 1. G. eorneum. 



2. Frond terete, at least in the lower part. 3. 



3. Fruit in ovate terminal expansions. 2. G. crinale. 



3. Fruit in terminal expansions of irregular form, the edges dentate or 



ciliate. 3. G. spathulatum. 



1. G. CORNEUM (Huds.) Lamouroux, 1813, p. -11: Fucus corneus 

 Hudson, 1798, p. 585; Turner. 1819, p. 146, PL CCLVII, fig. a. 



Kemp, June, July. Two specimens in the Kemp herbarium resemble 

 ordinary European forms; one is marked " var. k, abnorme Harvey" 

 but is hardly like the figure in Turner for that variety. We have DOt 

 ourselves found anything we should refer to this species. 



2. G. CRINALE Turn.) Lamouroux, 1825, p. 191; P. B.-A.. No.
