extending to the anterior border. On the right and left of 
this septum lie deep and extensive muscular impressions. 
Teeth moderately developed. In the dorsal valve is also 
found a median septum, which in the posterior half is 
scarcely distinguishable, but in the anterior half rises as an 
obtuse triangular process, reaching almost to the ventral 
valve. The tooth sockets are well developed. At their wall 
begins the brachial apparatus, the crural processes of which 
are moderately long and slightly pointed. After a short free 
course, nearly parallel with the inner surface of the valve, 
the limbs are applied to the inner surface of the valve, and 
then cease. Also from the median septum there stretches 
on either side to the inner surface of the valve a short little 
band, the ideal continuation of the hinder part of the limb.

Cryptopora brazieri, Crane; Hedley, Proc. Linn. Soc., New 
South Wales, 1906, vol. xxxi., part 3, p. 467, pl. Xxxvi., figs. 
and 2. Common at 17-20 fathoms around Masthead Tsland, 
Queensland. 
Dredged at 6 fathoms, off St. Francis Island, 2 alive; 
at 40 fathoms, off Beachport, 2 good; at 49 fathoms, off 
Cape Jaffa, 1 perfect ; at 62 fathoms, off Cape Borda, 27 per- 
fect; at 90 fathoms, off Cape Jaffa, large numbers; at 104 
fathoms, 35 miles south-west of Neptune Islands, 20 per- 
fect: at 110 fathoms, off Beachport, 10 perfect; at 130 
fathoms, off Cape Jaffa, 5 moderate: at 150 fathoms, off 
Beachport, 2 dead; at 300 fathoms, off Cape Jaffa, 4 dead. 
Its habitat in our waters seems to he at a depth of 60 to 110 
fathoms. I have never taken it at so low a depth as 20 
fathoms, that at which Mr. Hedley secured it in Queensland.
