4. Codiuiu petaloideum n. sp. 



Had. INDIC. Siboga Expedition. Stat. 81. Sabangkatan, Borneo bank, reef: dried and in alcohol. 



Plant small, bright green, 10 — 12 mm. in height, 5 — 7 mm. wide, complanate, obovate, 

 subsessile. Utricles of the external stratum subpyriform, obtusely rounded above, but often a little 

 impressed, small, 180 — 240 u. long, 115 — 180 [x wide, thin-walled at apex. [Figs. 193, 194]. 



This species is distinguished from all other species of the genus by its small size (fig. 193), 

 combined vvith its compressed shape and small pyriform utricles. The utricles (fig. 194) most 

 nearly resemble those of C. temie and C. Muelleri in shape, but are about one half as long 

 as those of C. tenue and about one third to one half as long as those of C. Mticlleri. And 

 both those species are quite distinct in habit, being filiform. C. petaloidea might be mistaken 

 tor dried, fiattened specimens of C. ovale, but an examination of their respective utricles reveals 

 at once that C. ovale is characterised by much larger utricles, nearly 1000 u. in length, and 

 200 u. in width, and almost cylindric in shape. The new species is represented by four specimens 

 only, one of which is preserved in alcohol.
