124 _ PALEONTOLOGICAL EVIDENCE OF 
V. lammellata exists, but with 7 op specific dliffessirms 
Our ca Pectens are not at all like our recent forms, but are 
_ peculiar—one P. foulcheri,no obis, is spinous, P. patledics, ‘nobis, is 
aly. imbricated, P. corioensis is delicately striated, P. coarctatus* 
and P. g ambierensis, nobis, are both weap granular ; in all of 
wie partiealars they differ much from our recent species. P. 
yahlensis, according to Brofess sor M‘Coy, so nearly resembles the 
well-known German Miocene species, P. Hoffmani, Goldf., as to 
be easily mistaken for it: ut the valves are both e in the 
ot fossil, while they: are different in the Australian. Cyprea, 
icia) gigas is a very peculiar and large species, differing very 
re from any form fossil or recent, while Zrivia avellanoides can 
scarcely be distinguished from Trivia avellana of the British 
Oligocene, and is very like 7. affinis of the French Miocene and 
British Lower Pliocene. The genera best represented in our. 
anal

resemblances are only remote. There is a far greater similarity 
between them and those of the Paris beta, but still it is not Mag 
close. None of our lower Tertiary Ceri thiade have been describe 
There is a Spondylus (S. gaderopoides, M‘Coy), which is exceedingly 
close.to S. bifrons, Munster, of the Miocene of Westphalia. Hal- 
otis ovinoides, M*Coy, and H. Mooraboolensis, are both forms with 
strong resemblances to H. ovina and H. nines Gray, respectively, 
both of North Australia.

all Australian paleontologists, They are described at some length 
in the Annals of Nat. Hist. for July, 1864, by Dr. Leith Adams, 
and the Bracheopoda i in the same paper by Mr. Thos. Davidson. 
He says the Maliese Islands, which extend about 29 miles, alk 
belong to one series, and are to be considered portion of an early 
Miocene equivalent, to the Hempstead beds of ms gland, which 
was regarded by Sir Chas. Lyell as Upper Eocen The fo

* As the name P. coarctatus was applied to a fossil figured by me which I 
thought was. identical with a European species, I now propose the name of 
5 a i ee for the same shell, as it has not been described, and is not P. coare-
