48 Mr. J. W. Jackson on Lusitanian 
Cryptopora and Argyrotheca, which are recorded from thie 
Australian and Atlantic-Mediterranean regions (the last- 
named is also fossil in New Zealand), and Amphithy7is, 
which is recorded from the New Zealand and Mediterranean 
regions. 
Doubtless a close study of other groups of animals would 
reveal similar analogies. 
In conclusion, I might point out that Melvill and Standen *, 
in their paper on “ The Mollusca of the Persian Gulf ete.,” 
remark that the Persian Gulf fauna bears a considerable 
generic analogy with the Mediterranean molluscan fauna, 
though so widely differing specifically. 
Supplementary Notes on the foregoing Paper. 
While the above paper was in the hands of the printer, I 
received from Dr. W. H. Dall a memoir dealing with the 
collection of Recent Brachiopoda in the United States 
National Museum t. In this report Dr. Dall has had occasion 
to revise the nomenclature of certain of the forms dealt with 
in the foregoing pages. The chief alterations are as follows :— 
Terebratulina caput-serpentis (Linné, 1767) should be Z. re- 
tusa (Linné, 1758); Mwhlfeldtia truncata (Linné, 1767) 
becomes MM, disculus (Pailas, 1766), though in this I cannot 
readily concur, as Pallas’ figures are very unlike the species 
in question; the Lacazella mediterranea (Risso) from Mauritius 
(Sir H. Barkly) is regarded as a distinct species under the 
name L. mauritiana, Dall; Kingena alcocki, Joubin, is 
placed in the genus Frenulina, which, from a recent study of 
a specimen in the British Museum, I can corroborate: the 
loop, if anything, is very slightly more advanced than that of 
the genotype Frenulina sanguinolenta (Gmelin) ; it possesses, 
however, the same type of cardinalia, also dental plates and a 
fused pedicle-collar in the ventral valve. Dall’s specimen is 
from the Sulu Sea (‘ Valdivia’ Exped.), that belonging to 
the British Museum is labelled “ Off Travancore, Dr. Bloch- 
mann.” Terebratulina valdiview, Blochmann, is recorded by 
Dall (op. e¢t. p. 301) from numerous localities (other than 
the type-station, off Nias, Sumatra), including Korea, Philip- 
pine Islands, and China Sea. With regard to the Morrisia 
gigantea, Deshayes (Isle of Réunion), Dall places this tenta- 
tively in Pantellaria (olim Muhifeldtia) echinata (F. & OU.), 
which he also records from the Cape of Good Hope, New 
South Wales, Barbados, and Sand Key, Florida. From
