T. I, f. 15x400 (after Wallich Mscr. No. 107). 



This form is apparently between the Cl. peracerosum Gay Monogr. p. 75, t. II, 

 f. 18, and the typical form. The yellowish-brown membrane is notable. It may be 

 that the Cl. lanceolatum of Kutzing is only a sub-species (subtilissime striolatum, Ktz. 

 Spec. Alg. p. 165) of this typical form; Brébisson, Liste p. 152, thinks they can 

 scarcely be separated.

3. C. arcuatum (Liste p. 149, t, II, f. 38, 1856; Ralfs Br. Desm. p. 219, 1848; C. Diance 

 Klebs Desm. Pr. p. 11, non Ehrb.). 



Long. 220, lat. 19 u. T. I, f. 17x400. 



Klebs is apparently in error in attributing this to Cl. Diana, as the absence of 

 the little indentation at the apices of that species, (the petit museau mentioned by 

 Brébisson,) is characteristic. 



4. C. lunula (Muller) Mexgh. (Nitzsch, Ehrenberg, Morren et aliorum, ex p., excl. syn. 

 plur.; Mengii., Synops. in Liniuea, p. 231, 1841; Vibrio lunula, Muller Naturforsch.

Forma. F. paullo minor quam. f. typica, cytiodermate pallide Iutea (non b colo-

Long. 100, lat. 15 u. T. I, f. 20. 



This species appears to me but a variety of C. Jenneri Ralfs, with acute apices; 

 possibly interinediate between that species and C. Leibleinii Ktz. 



6. C. Ehrenbergii Menoh. (Synops. p. 232, 1841; Cl. lunula Ehrb. ex. p., t, Y, f. XV, 2, 

 1838; Cl. moniliferum c. Ekrenbergii Klebs. Desm. Preuss. p. 10, f. 4). Forma, ad 

 formara a Klebs 1. c, f. 4 a accedens, sed paullo tenuior.

Both this and the specimen mentioned by Klebs are smaller than the typical 

 European form.
