medesmia laevissima, the type of Folitispa. The 
name Neo folitispa is proposed here to receive 
them. Amphilectus ungiculatus is certainly very 
close to Neofolitispa, but without reference to 
type material it cannot be placed in the genus. 
Probably Esperiopsis viridis Kieschnick should 
be included in Neofolitispa, but this cannot be 
verified from the literature. 
Monanchora Carter is retained for M. clath- 
rata, a poorly known Australian sponge which 
Levi (1961) has incorrectly recorded from the 
Philippines. 
DISTRIBUTION : Puerto Galera, Philippines 
(de Laubenfels); Palau Islands, Marshall Is- 
lands (de Laubenfels). 
GENUS Desmacella Schmidt 
Desmacella lampra de Laubenfels 
Desmacella lampra de Laubenfels, 1954, p. 
150, fig. 98. 
OCCURRENCE: Sta. 104. 
REMARKS: This sponge is encrusting to a 
thickness of 1.2 mm over a specimen of Teles to 
and in the fragment collected shows no tend- 
ency to become massive. The color in alcohol 
is salmon pink (RY-R 6/8). The holotype 
(usnm 23088) has an identical external color 
in alcohol. The dermal membrane contains tan- 
gential megascleres, and rare sigmas. 
DISTRIBUTION : Marshall Islands ( de Lauben- 
fels ) .

Pseudaxinyssa pitys de Laubenfels 
Fig. 25 
Pseudaxinyssa pitys de Laubenfels, 1954, p. 
178, fig. 117. 
OCCURRENCE: Sta. 92 A, Sta. 140 (fragments 
only ) . 
REMARKS: This specimen is from the same 
location as the holotype (USNM 23103 and 
Bishop Museum 137) and is closely compara- 
ble with it in size and structure. The spicula- 
tion of both the type and the present specimen 
includes styles and occasional strongyles as 
modifications of the oxeas. 
SPICULES: Oxeas; 612-812 X 5-1 6 /z. The 
holotype shows a corresponding range of spic- 
ule size. 
DISTRIBUTION: Palau Islands (de Lauben- 
fels ) . 
genus P by cop sis Carter 
Phycopsis sp. cf. terpnis de Laubenfels 
Phycopsis terpnis de Laubenfels, 1954, p. 176, 
fig. 11 6. 
occurrence: Sta. 220A. 
DESCRIPTION : A massive, cake-shaped sponge, 
13 cm in diameter, 6.5 cm thick. Prominent 
circular oscules, 0.8-1. 0 cm in diameter, are 
scattered over the upper surface. Each osculum 
is surrounded by a low collar, 0.4-0.8 cm high 
with walls 0.8-2. 5 mm thick. In all cases the 
osculum functions somewhat as an exhalant 
cloaca, receiving 3-12 small exhalant openings 
about 1.0 cm below the sponge surface. 
COLOR: In alcohol, white. 
TEXTURE: Crisp and brittle. 
SURFACE: Uneven, hispid. 
SKELETON: A confused mass of oxeas, 670- 
1100 X 8-22/a (877 X 15.5/*). The structure
