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, pi. xxxvi., figs. 1 

 and 2. Common at 17-20 fathoms around Masthead Island, 

 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 be 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.
