т. The figure shows the greater part of a single tetrasporic plant in dorsal view. Th 
nodes indicate the position of the ventral haptera, which are 
commonly visible through the thallus.

3. One of ge apices of ps pubad in latero-ventral view, showing a young boring 
haptere in profile. 
4, 5. Outlines of cross sections of the thallus, each passing through a haptere. 
6,7. Outlines of cross sections of narrower and less flattened segments of the thallus. 
8. A median longitudinal or sagittal section of a thallus segment, showing protoplasts 
in outline. 
9. Apex of a young narrowly acuminate branch, showing apical and surface cells. 
то. Apex of one of the main segments, showing apical and surface cells. 
тг. А node in ventral view, showing haptere and four rudimentary ventral branches 
just anterior to it 
12. Tetrasporangia and vegetative surface cells. (The arrow points towards apex 
of the sporangiophore. 
All of the figures are drawn from the type material (Island of San Lorenzo, 
Coker 59 p.p.). Figures т and 2 are enlarged 9 diameters; 3 and II, 40 diameters; 
4-7, 55 diameters; 8 and 12, 245 diameters; 9 and то, 675 diameters. 
Gelidium pusillum, epiphytic on Gigartina Lessonii, has been 
reported from Paita by Piccone (Alg. Vettor Pisani 75. 1886). 
The same author reports Gelidium crinale chiloense from the 
Island of San Lorenzo, near Callao.

Fragments 4-5 cm. long, tripinnate; main rhachides terete or 
nearly so, becoming flattened above, т mm. in diameter; branches 
distichous or here and there irregularly 3- or 4-ranked, the margins 
of ultimate ramuli obscurely crenate-dentate; sporangiophores 
spatulate, lingulate, ог obovoid-cuneate, 1-3 mm. long, 0.7-1.0 
mm. in greatest width, their margins dentate. 
The material is so evidently fragmentary that no reliable con- 
clusions as to the size of the plants can be drawn, but they are 
probably smaller and are certainly less densely pinnate than those
