402 LIST OF LAMP SHELLS FOUND IN PORT JACKSON, ETC. 



From what I can make out, the Australian species of recent 

 Brachiopoda would be, (or of which I have seen specimens) 

 Terebratulina cancellata. Terebratulina (the specimens you have 

 recently dredged in Port Jackson). Waldheimia australis. 

 Magasella Cumingii. Megerlia mnguinea. Megerlia pulchella. 

 Kraussina Lamarckiana. Kraussina Atkinsoni, Woods, M.S., a 

 smooth small species from Long Bay, Tasmania. Lingula exusta, 

 Moreton Bay. Lingula tumidula, and MwpMana occur in same 

 locality, and are of the same colour. I often ask myself whether 

 they are distinct species, or whether Lingula tumidula may not be a 

 very wide variety of Murphiana. This is a point which Australian 

 Zoologists must decide, as I have no opportunity of so doing, as 

 there are only two specimens of the form tumidula in the British 

 Museum ; the form Murphiana is common, I have two or three 

 specimens." 



Mr. Davidson forgets to mention in his list to me Megerlia 

 Willemoesi, described by him from specimens obtained by the 

 Challenger off Twofold Bay, five examples of this interesting 

 species were dredged in lat. 36° 56' S., long. 150° 30' E., in 120 

 fathoms. Twofold Bay is in New South Wales, and not South 

 Australia, as quoted in the Proceedings of the Royal Society 

 England. 



Lingula hians, Swainson, is also found in Port Jackson, very 

 rare, by Mr. G. F. Angas, F.L.S. ; recently by me, New Caledonia, 

 Port Curtis, North East Australia. 



In reference to Bird Island being on the North Coast of 

 Australia — it lies outside the Great Barrier Reef at least 300 miles 

 off the North East Coast, exact position is 22° 10' 30" S. lat., 

 155° 29' 21" E. long., any chart of the Western South Pacific will 

 show the position. 



Having recently obtained a series of Kraussia Lamarckiana 

 under a large stone at outer Double Bay, Port Jackson, I intend 

 sending them to Mr. Davidson. I take the opportunity of showing
