This species is closely related to S. elegans, V., S. tenuis, 
V., and less so to S. obliquus, Stud., but its differences are 
well marked and easily separate it. The larger of two speci- 
mens in the collection is about 5:5 centim. high, its base being 
about 6 millim. thick and its branchlets about 1:5 millim. 
thick close to their extremities. Many large swollen ampulla 
occur on this specimen, being quite absent on the smaller. 
On this smaller specimen, however, there occur on the branch- 
lets many small, raised, white porous masses, which are very 
rarely present on the larger specimen, and which, when scraped 
away, reveal circular cavities in the coenosteum. ‘These are 
markedly different from the large, coloured, non-porous 
ampullee. 
Distichopora breviserialis, n. sp. 
Coenosteum of a rather deep flesh-red or pale aurora-red 
colour, branched, very compact, irregularly flabellate, with 
the surface granulated, roughened, and minutely canaliculated ; 
branches often coalescent, rather short, thick, uneven, often 
twisted, almost round above, but much compressed, at the base 
especially, where three or four branches arise together in the 
same plane; branchlets very short, thick, and obtuse, of a 
deeper colour than the rest of the ccenosteum; cyclosystems 
almost entirely absent from the main branches and the basal 
parts of the longer branchlets, primarily developed on opposite 
sides of the branched ccenosteum in well-marked furrows, as 
indicated on the extremities of the branchlets, but becoming 
obliterated by growth, except where incipient branchlets are 
present on the main stem and branches and at the extremities 
of the long branchlets; at these extremities the dactylopores, 
which are very small, are generally situated on raised lateral 
ridges on each side of the furrow, with many smaller pores on 
the face of the branchlets, but these gradually disappear by 
overgrowth; the gastropores are very irregularly shaped, 
large and small often alternating at a distance apart about 
equal to their diameter, with deep, long, and thin styles, 
finely plumose ; large, swollen, distinct vesicular ampulle are 
absent, but on many parts of the branches and branchlets occur 
rough masses of small irregular cells, often open, which seem 
to be ampulle. 
Hab. guM. 
The specimen of this species consists of a ccenosteum about 
7 centim. high, with six main branches, the thickness of 
which is about 7 millim. at base, being much wider in the 
plane of the flabellum. Many of the branchlets are broken off
