Near to C. ps.-Broomei Wolle (cfr No. 97) but differs in the far greater num- 

 ber of lines of granules, the granules theraselves being liiuch smaller than in tliat 

 species. C. margaritiferum? Walt.ich Mscr. No. 146 A.

I am not at all sure of these dimensions, as no data are appended to Wallichs 

 sketch. The inonstrositv is very peculiar, in fact unique, the two subsidiary seg- 

 ments proceeding at right angles from the side portions of the central frond. The 

 general appearance of the central frond is rnuch like Wittrocks var. in Skand.

A form exactly like this appears from the Himalayas (ex Utricularia stellari, 

 conini. G. v. L.); it is a little smaller than the Greenland form. long. 65 — 68, lat. 

 46 — 49 ,". Two speciinens observed. 



103. C. spiculiferum. n. sp. C. minus, tertia parte longius quam latum; angulato-circulare; 

 semicelluhe indistincte 9-goiiEe, dorso elliptico-pentagoine, lateribus bi-angulata3; 

 angulus unusquisque spiculo brevi unico munitus, sed angulus apicalis tuberculos 

 duos breves conicos prsebet; in centro quaque semicellula tuberculos parvos duos 

 habet, ventre semicellulariun inflato; reliqua membrana laevi; sinu profundo, angusto, 

 externe non ampliato. A latere visum paullo constrictum, semicelluhe angulato- 

 ovales; a vertice elongato-truncatum, quasi 6-angulatum; angulis medianis indistinctis.

 C. gemmatum (tvpe) Wallich, Mscr. No. 139. Nearest to C Warmingii Borg. 

 (Des. Brås. t. IV, f. 34) but is mucli more angular. 



104. C. Indicum, n. sp. G. minus, tam latum quam longitm, sub-circulare; semicelluhe 

 dolabriformes, dorso aemicirculares, basi rosträtas, productse, dejeotaj; margine crenato- 

 granulata 1 ; membrana granulosa, tumorem centralem annulo granulorum (6 — 7) orna- 

 tum habens; sinu amplo, sub-profundo, triangulari, extrorsum constricto fere occluso; 

 apicibus semicellularum dentibus ereetis 4 armatis. A vertice visum oblongo-trun- 

 catum, medio tumidum; a latere mediocriter constrictum, sinu rotundato, semicellula? 

 globosa- apice truncatae.

IVom Wallich's drawing it appears tliat each semicell contains two amylnm 



corpuscles. It seems closely related, in general outline, to C. rostratum Turnek
