Sponges of Palau, I— BERGQUIST 
199 
agreed that the removal of Tetilla merguiensis 
Topsent 1897 to AmphiPethya as suggested by 
Wilson is desirable, but Dandy’s view as to the 
presence of poriferous pits in Stelletta bacca 
Selenka is well reasoned and is upheld. Further, 
Wilson questions the synonymy of P. eccentrica 
Row with P. bacca, claiming that the great 
irregularity of the triaenes justifies the separa- 
j don of this species. Malformed triaenes are the 
1 rule in the Palau specimen and all modifications 
described by Row for P. eccentrica can be ob- 
served. P. cineriformis Dendy also possesses 
malformed triaenes. In view of this the sep- 
aration of P. eccentrica cannot be maintained, 
j The status of Paratetilla lipotriaena de Lauben- 
fels (1954:244) is uncertain. The hole-type 
( usnm 23049) has been re-examined and has 
been found to possess occasional prodiaenes, 
promonaenes, and anatriaenes with reduced 
rays. The cali.hr ops or orthotriaenes are identi- 
cal with those of the specimen assigned here to 
P. bacca; other skeletal elements, color, and 
| general morphology also agree with the Palau 
specimen. In view of the abundance of triaenes 
in my specimen and their scarcity and reduced 
form in P. lipotriaena , this species is retained 
| as a valid one for the present. 
DISTRIBUTION : Indian Ocean and western 
Pacific. 
GENUS Cinacbyra Sollas 
Cinacbyra australiensis (Carter) (complex of 
species ) 
RESTRICTED synonymy (for extensive syn- 
onymy refer to Burton, 1934): 
Tetbya cranium var. australiensis Carter, 
1886, p. 127. 
Cinacbyra australiensis Burton, 1934, p. 523. 
Cinacbyra australiensis de Laubenfels, 1954, 
p. 242, fig. 166. 
OCCURRENCE: Sta. 47, 125, 200 (2 speci- 
mens ) . 
DISCUSSION: The four hemispherical speci- 
| mens in the collection are not identical in spic- 
i ulation but are very similar in external form. 
' There is variation in the size and degree of 
j torsion of the sigmaspires, those in specimen 
I Sta. 47 being small and tightly curved while 
those of the remainder are larger and more 
open. Microxeas are variable in their number 
and degree of spination; they are rare and 
occasionally roughened in the specimen from 
Sta. 220, relatively abundant and roughened 
in that from Sta. 125, relatively abundant and 
smooth in that from Sta. 47. 
Protriaenes and anatriaenes are present in all 
specimens. 
DISTRIBUTION: Australia, Malay area, Indian 
Ocean.
