(3) It was interesting to find a recurrence of the remarkable Pachyclavularia erecta which 
Roule described many years ago from Amboina. We were able to compare the Siboga specimens 
with his, through the kindness of Professor Revilliod, Director of the Natural History Museum 
in Geneva. 
(4) It has seemed justifiable to establish a new genus Protodendron for a very interesting- 
primitive form, previously described as Coelogorgia repens by Thomson and Henderson. 
(5) The multitudinous monotony of the genus Xenia was somewhat relieved by re¬ 
finding the dimorphic Xenia ashworthi , and embedded in it a parasitic Copepod, — probably a 
unique record. 
(6) Worthy of special mention on account of its striking beauty — primus inter pares — 
is Nidalia splendens n. s'p. 
(7) Very puzzling geographically, and in small tubes without labels, are two fragmentary 
specimens which we cannot Tut refer to the species described by Koch as Daniela koreni and 
Cereopsis studeri. 
(8) As an instance of a species definitely marked by a triviality, we may call attention 
to Lernnalia squamifera which shows an interesting developmental series of minute sculptured 
scales, and has them not only as usual on the tentacles, but dusted over the body in a 
remarkable way. 
(9) After much consideration we have established an annectent genus Umbellulifera for 
a form, Paraspongodes striata Thomson and Henderson, which has been much bandied about. 
Along with two others species (one. new) this type appears to us to be of generic standing and 
a connecting link between Dendronephthya and Eunephthya. 
(10) Of interest is the large representation of the genus Stereonephthya, with no fewer 
than eight new species out of a total of nine. 
(11) The species of Dendronephthya — probably in a mutating phase — remain very 
difficult to deal with, but we have verified and extended Sherriffs’ useful idea of laying the 
main emphasis on the architecture of the l p°i nts ’ °f the anthocodiae. No fewer than 32 species 
have had to be dealt with, of which 6 are new. 
(12) Miss Chalmers has made a careful revision of the genus Siphonogorgia including a 
critical consideration of the specific characters. Out of 23 species dealt with it has been necessary 
to regard 8 as new. 
(13) We have been able to revise and confirm the interesting and sharply defined genus 
Cactogorgia established by Simpson. A clear-cut new species is added. 
(14) The remarkable family of Fasciculariidae, with the polyparium retractile into an 
involucre, is represented by Paralcyoninm elegans and by four species (two of which are new) 
of Studeriotes 1 homson, one of the most remarkable of all Alcyonarians.
