This species is closely allied to C. mucronata, with which it 
has been found on more than one occasion, including that on 
which the type-specimens of both species were discovered. Its 
tylostyles are, like those of C. mucronata, of two types, one of 
which is remarkable for the great expansion of the lower part of 
the shaft. The tapering of the point is, however, regular and the 
spicules is never mucronate. The other type of tylostyles is slen- 
der and in no way remarkable. The species is apparently more 
robust in its growth than C. mucronata. 
C. ensifera, which was originally described as occurring in the 
coral Is¢ts from an unknown locality, is abundant in dead reef- 
corals from the Mergui and Andaman archipelagoes.

Topsent has discussed this species and its synonomy in great 
detail and further references are unnecessary. It may be noted, 
however, that Carter’s provisional species Cliona stellifera was 
founded on the macroscleres of this Cliona and the microscleres 
of a parasitic Chondrilla. I have found the two sponges in close 
association in his original specimen of dead coral from Mergui. 
C. viridis is a cosmopolitan species evidently common in dead 
coral in the Mergui Archipelago and off the coast of the mainland 
of Burma. It was originally described from the Mediterranean 
and is known from the Gulf of Mexico, the Red Sea and many 
other widely separated localities. 
Cliona orientalis, Thiele.

1900. Cliona ornentalis, Theile, Abh. senckhenb. Natur. Gesel- 
isch. XXV, p. 71, pl. iii, fig. 24. 
Thiele pointed out in 1900 (op. cit.) that the sponge described 
by Carter from Mergui under the name of Suberites coronarvius was 
not identical with the species the latter had previously described 
under the same name from the West Indies, but actually aspecies of 
Cliona. He redescribed it with fresh figures of the spicules and 
named it Cliona orientalis. A re-examination of a part of Carter’s 
Burmese material shows that Thiele was right in both conten- 
tions.
