R. W. H. ROW—REPORT ON THE SPONGES: NON-CALCARHA. aol 
PHAKELLIA DONNANI (Bowerbank). (PI. 38. fig. 16.) 
Synonymy :— 
1873. Isodictya donnani, Bowerbank (2). 
1887. Axinella donnani, Dendy (12). 
1904. Phakellia donnani, Dendy (11). 
Two very small specimens, both of them cup-shaped, occur in the collection. 
The largest has been photographed (PI. 38. fig. 16), and it measures 14 mm. 
in height and 14 mm. in diameter at the widest part of the cup. 
The general appearance of both specimens is similar to the specimens 
described from Ceylon by Dendy (11). 
Locality. The labels in the bottle containing these sponges were com- 
pletely macerated, but there seems to be some evidence in favour of the 
opinion that they were obtained at Cape Elba. Out of the 56 bottles in 
which the sponges of the Crossland collection were sent to me, 23 were 
indicated on the labels inside the bottles merely by a number, and with them 
were sent MSS. notes relating to these numbered bottles. The numbers in 
the MSS. ran from 1 to 24, but only nos. 1-18 and 20-24 were present in 
the bottles themselves. The remaining 33 bottles were labelled as follows : 
one had the labels macerated, and is now being discussed, the other 32 had 
MSS. notes on the labels in the bottles stating the spot where the specimens 
were ootained &. There is therefore a considerable possibility that this 
bottle with macerated labels is the missing no. 19, which was described in 
the MSS. as “ From a piece of coral, brought up from 10 fathoms by a fishing- 
line, near a reef off Cape Elba, Egyptian Sudan Frontier.” 
Distribution. Red Sea; Ceylon ; Madras. 
PHAKELLIA PALMATA, n. sp. (Pl. 89. figs. 20, 21; Text-fie. 26.) 
This new species has been created for the reception of a single specimen. 
It consists (Pl. 89. fig. 20) of a single frond-like lamella, growing upright 
on a cylindrical stalk. The base of the sponge is a flat circular area, but 
there are no remaining indications of tlhe actual support. From this there 
arises a short stalk, circular in section, and about 10 mm. high and 6 mm. 
in diameter. The main body of the sponge is a broad, flat lamella, 50 mm. 
wide, 40 mm. high, and from 3 mm. to 5 mm. thick. From the edge of this 
lamella a number of very short conical processes arise, some of them merely 
slight protuberances from the sponge, some of them 5 mm. or 6 mm. in 
height. At the summit of each of these are the oscula, which are thus 
arranged around the edge of the sponge lamella, on special oscular processes. 
No oscula occur in any other position in the sponge. 
The surface of the sponge is coarse and uneven ; small ridges and irregu- 
larities occur all over it, none of them definite enough to disturb the general
