Brachiopods in the Persian Gulf. 49 
Deshayes’ description and figures I am not convinced of the 
identity of “gigantea” with the Aliuh/f ldtia echinata, F. & O., 
but am more inclined to refer it to JL. truncata, var. pauct- 
striata. The presence of JMihlfeldtia at the Cape and 
Australia is remarkable, and of great importance from the 
point of view of distribution. I am able to record the 
presence of an immature example of J/. truncata, labelled 
*S. Atriea. J. HH. Ponsonby evll., 1900. 6.13.4.” in the 
British Museum. This point, and the occurrence at the Cape 
of other new species with Mediterranean affinities, will be 
discussed in a future memoir on the Biachiopoda in the Cape 
Town Museum. 
In the foregoing pages I omitted to call attention to 
Dr. J. H. Ashworth’s discovery of larval forms of Léngula 
anatina in the Red Sea*. InJune 1914 this author obtained 
“fourteen larve of the above in the southern part of the Red 
Sea, lat. 15° N., long. 42° E.; and in October of the same 
year two larve were again taken in the same neighbourhood ; 
one larva in the Indian Ocean, about 4° south of Colombo; 
and six larvee of Pelagodiseus atlanticus (King) a little to the 
south of Cape Comorin, 8. ludia. 
While examining the Brachiopoda at the British Museum 
recently I discovered a specimen (in spirit) labelled ** Lingula 
anatina. Durban. J. 11. Ponsonby. 99. 4.14.1.” ‘This 
requires further study. 
According to Dall (op. cit. pp. 262-263) Lingula anatina 
should be known as Z. wnguts (Linné, 17538). 
The following are to be added to the f:una of the Arabian 
Sea :—Lingula translucida, Dall, 1920, Karachi; also found 
at Java and the Philippine Islands (Dall, op. et. p. 264) ; 
Lingula hians, Swainson, Bombay (Melvill and Aber- 
m bie) F. 
This is not the place to discuss Dr. Dall’s useful List of 
Recent Brachiopoda, but a good opportunity is provided to 
call attention to the fact that Dall’s new subgenus Pereudesia 
(p. 360) is antedated by my Coptothyris (Oct. 1918) f. It is 
unfortunate that Dr, Dall has auticipated many of my own 
conclusions, which were arrived at during researches dating 
from before the war, various duties during the interval having 
prevented me from writing them up for publication.
