Sponges of Kaneohe Bay — DE LAUBENFELS 
8 by 200 g , but sometimes 9 by 230. A few 
thicker, shorter ones, 12 by 180 g , may be 
found, for example. The microscleres are of 
two sorts. There are abundant, commonplace, 
arcuate isochelas, 27 g long. In the aberrant 
Kailua specimen there were also some only 
15 g long. A second category of microscleres 
appears to be a sort of sigma. It is C-shaped 
rather than S-shaped, is in one plane, not con- 
torted. This suggests that it might be a re- 
duced chela, and accordingly a search was 
made with immersion microscopy for traces 
of clads. At least one inward pointing clad 
is certainly present, perhaps three. The dif- 
ficulty of being sure is due to the size of this 
spicule. Its chord length is 13 g, its diameter 
1 g, the clad or clads are less than 1 g in 
length, and at the widest about a third or a 
fourth of a micron in diameter, tapering to 
a point. 
The species name is given in honor of 
Hawaii. 
Neoadocia new genus 
This genus is here erected in the family 
Adociidae, with the following species, Neoa- 
docia mokuoloea, as genotype. It should be 
emphasized that this is a genus with an ec- 
tosomal skeleton of tangentially placed oxeas. 
overlying an endosomal skeleton of oxeas, 
with raphides as microscleres. This is like 
Adocia except for the addition of raphides; 
it is set off from all other genera in the family 
by the possession of these microscleres. 
The generic name is selected to show the 
close relationship to the genus Adocia. 
Neoadocia mokuoloea new species 
Fig. 8 
The holotype of this species is designated 
as spirit-preserved specimen, U. S. National 
Museum, Register Number 22745. It was 
collected September 10, 1947, at a depth of 
about 2 meters, near the dock at Moku O Loe 
(location 6, Fig. 2). Only the single speci- 
15 
men was found. I have repeatedly searched 
for others but without success. 
The specimen is a mass 2 by 3 by 3 cm. 
Two holes go right through it, perhaps caused 
by foreign objects about which it grew; one 
of these is 3 mm. and the other is 9 mm. in 
diameter. The color in life was golden-yellow 
for all the interior and much of the exterior, 
but externally there were rosy-red patches. 
The consistency is very soft. 
The surface is exceptionally punctiform. 
It is liberally perforated by apertures 1 mm. 
in diameter, more than 20 per square cm. of 
surface, on all surfaces except the surface of 
attachment. It is not clear which of these 
apertures are inhalant and which exhalant, 
unless it may be that all are pores, and the 
two large openings mentioned above may be 
the oscules. It would be interesting to have 
additional specimens and so be able to ascer- 
tain more of the structure of this species.

camera lucida drawing, X 444. A, megasclere 
( oxea ) . B, microscleres ( microxeas ) , or raphides. 
The ectosome contains a tangent dermal 
skeleton of smooth diacts, over subderma 1 
spaces. The endosome is cavernous, with an 
isodictyal reticulation of smooth diacts and 
few or no spicule tracts at all. The mega- 
scleres are all smooth oxeas, 6 by 120 to 6 
by 135 g. The microscleres are commonplace 
raphides, about 0.5 g thick, but upwards of 
100 g long. 
Adocia haeri occurs in the Philippine Is- 
lands. It was first described as Renieva implexa 
variety baeri by Wilson (1925: 398) and 
made a species by de Laubenfels (1936: 
328). This Adocia is very different from 
mokuoloea in appearance, being nearly black. 
It contains a few very thin spicules, but these
