P. COMPRESSUS, Ten. -Woods ((^oiwci/atli us ), sp. (D), p. 302, 

 pi. v., fig. 1, (F), p. 4, pi. i., fig. 3. 

 Described from specimens dredged off Port Stephen, New 

 South Wales, at 71 fathoms. Dredged by Dr. Verco in Gulf

Tkematotrochus verconis, Dennant (F), p. 5, pi. i., fig. 4. 

 This genus, which is exclusively Australian, was estab- 

 lished by Tenison-Woods for a Lower Tertiary coral of Vic- 

 toria. It is interesting to find a representative of this early 

 Tertiary genus still living in our waters. Gulf St. Vincent 

 and Backstairs Passage, 15-22 fathoms. 



Deltocyathus vincentinus, Dennant (F), p. 6, pi. ii., fig. 1. 

 "Examples of this coral were dredged in all but two of 

 the fourteen stations mentioned by Dr. Verco, and generally 

 in great abundance." — Dennant. Depths, 9-22 fathoms. 



Flabellum australe, Moseley (H), p. 173, jal. vii., figs. 4, 

 5, (G), p. 151. 

 The "Challenger" specimens were taken in 120 fathoms 

 off Twofold Bay, New South Wales. Later, it was taken in 

 great numbers 20 miles north-east of Port Jackson, by Hedley 

 and Petterd, at a depth of 250 fathoms. Dredged by Dr. 

 Verco oft' Cape Jaffa, 90-130 fathoms, and off Beachport, 

 110-200 fathoms. The genus is represented by eight species 

 in the older and newer Tertiaries of Southern Australia. ' 



Sphenoteochus emarciatus, Duncan, var. perexigua, Den-

 excisiis, (J), vol. xxvi., p. 298, pi. xix., fig. 86, (G), 

 p. 151. 

 The specific type was obtained from the Lower Tertiary 

 of Muddy Creek, Victoria. Dennant's variety differs only 

 slightly from the Tertiary fossil form. Dredged east of 

 Neptune Islands at 45 fathoms, off Cape Jaffa at 90 and 130 

 fathoms, and off Beachport at 49 and 150 fathoms. 



Deltocyathus rot^formis, Ten. -Woods (D), p. 306, pi. v., 

 fig. 2, (G), p. 154.
