MARINE ALGAE PROM EAST] ISLAND 309 



On the other hand the glands themselves are rather large and each group 

 mostly consists of a good number of glands (10 — 20 or more). They are 

 gathered upon a smaller cell situated among the large wall cells; sometimes, 

 too, this small cell carries another smaller one upon which the glands are borne. 

 The glands are oblong, about 20 ij. broad and 40 ;j. long 



In a few cases I have found the glands divided into two cells (Fig. 50 e). 



All the material was sterile. 



Of the known species of Chrysymenia, the present one is most closely 

 related to C. Uvaria (L.) J. Ag. (esp. the Mediterranean form), piriformis Borgs. 

 and microphysa Ilauck. It differs from C. Uvaria in growing less high, by the 

 much smaller number of vesicles on each main stem, by the larger, shortly 

 pedicellate vesicles, further by the gland-cells being larger and arranged in 

 dense groups, while in C. Uvaria these cells are small, rounded and scattered 

 singly over the wall (comp. my fig. 388 in Mar. Algae D. W. I., vol. II, p. 403). 



From C. pyriformis it also differs in the lower, more condensed habit, in the 

 irregular branching and shortly pedicellate vesicles, while, in the former, generally 

 also in C. Uvaria. the sessile vesicles form a raceme along the main stem and 

 branches. C. pyriformis has larger and more pyriform vesicles. The cortical 

 layer in the vesicles is thicker and more firmly built in C. Skottsbcrgii. The 

 glands are grouped in the same manner in both, but they are larger in the 

 latter and more numerous to each group. The quite robust stem is also more 

 strongly built in the new species. It should be remembered, that this was 

 collected in tide-pools, while C. pyriformis is a sublitoral species. For more 

 details I refer to my description of the latter. 



Finally, C. micropJiysa is a much smaller plant, mostly with a single 

 terminal vesicle, less often with one or two lateral branches in addition. For 

 a detailed description see P. KUCKUCK, Beitr. zur Kenntnis der Meeresalgen. 13 

 (Wiss. Meeresuntersuchungen, N. F. Bd. V, Abt. Helgoland, 191 2). 



Area of distribution: Endemic. 



Champia Desv. 

 Ch. sp. 



In a glass tube with various algae a small fragment of a CJiampia was 

 found. Had it come from the West Indies I would have named it Ch. parvula 

 without hesitation, but as this species has not been reported from the Pacific 

 with certainty, I prefer to leave it unnamed, the more as it is sterile, the 

 arrangement of the tetrasporangia remaining unknown.
