Family CLIONIDAE. 
The following notes on the Clionidae are based on a small col- 
lection recently made by Mr. S. W. Kemp at Port Blair in the 
Andamans. All the specimens are from shallow water and, ex- 
cept the first, from dead reef-coral. 
Cliona carpenteri, Hancock. 
Shells of edible oysters (Ostvza viriginiana, Gmel.) from the 
head of Port Blair harbour are riddled with the galleries of this 
sponge, precisely as shells of the same species of oyster are riddled 
with those of C. vastifica in lagoons on the east coast of con- 
tinental India. 
Cliona mucronata, Sollas. 
Well preserved specimens .of this peculiar sponge occur in 
fragments of dead reef-coral with those of the two following species. 
They agree closely with Sollas’s original figures in respect of the 
structure of the characteristic diaphragms. 
Cliona quadrata, Hancock. 
1849. Cliona guadrata, Hancock, Ann. Mag. Nat. Hist. (2) Ill, p. 344, 
pl. xv, fig. 6. 
1881. Cliona warreni, Carter, ibid. (5) VII, p. 370, pl. xviii, fig. 6. 
1900. Cliona quadrata, Topsent, Arch. Zool. expérim. (3) VIII, p. 54. 
Topsent is undoubtedly right-in regarding Carter’s C. war- 
vent, which came from the Gulf of Manaar, as synonymous with 
Hancock’s species of unknown frovénance. Well-preserved speci- 
mens are present in Mr. Kemp’s collection. 
Cliona kempi, sp.nov. 
This species is closely allied to C. lobata, Hancock and C, 
michelini, Topsent, but is distinguished from both by the com- 
plete absence of microscleres. 
The galleries are almost cylindrical but swell out slightly 
at intervals. ‘They branch sparingly, giving off slender lateral 
branches that bifurcate acutely. The whole growth is slender 
and sparse. Diaphragms containing spicules that lie transversely 
occur at irregular intervals. The galleries lie completely in one 
plane, parallel to and only a short distance below the surface of 
the coral. 
The papillae are numerous but of very small size. They are 
each guarded by a dense mass of upright spicules which, at any 
rate in the centre of the papilla, have a somewhat spiral arrange- 
ment. 
There are numerous large cells in the parenchyma that con- 
tain granules of a comparatively pale brown colour.
