Orbicula tenuis, Sowerby, reported from Chili and Port Lin-. 
coln: this latter locality is certainly erroneous, no collector 
having taken it, so it is erased from our list. 
In vol. xi., op. cit., 1888, p. 69, Professor Tate added 
Magasella cumingi, Davidson ; and in vol. xiv., 1891, p. 269, 
Terebratula wyvillei, Davidson, dredged by the “Challenger” 
in lat. 42° 22’, which is a considerable distance off our shores.

This is now named Liothyris wyvillet. 
To the five species, belonging to five different genera 
above recorded by Professor Tate, we are able to add in this 
paper two previously-described species, viz., Avraussina 
atkinsoni, Tenison-Woods, and Cryptopora braziert, Crane; 
and five species hitherto undescribed, viz., Magasella vercot 
and Jf. jaffaensis and Cistella australis, all of Blochmann ; 
and Magasella radiata and Terebratulina cavata, both of 
Verco, bringing our number up to twelve species belonging 
to seven genera. 
NEW BRACHIOPODS FROM SOUTH AUSTRALIA. 
By EF. Birocumann, Tubingen. 
Dr. Verco, of Adelaide, had the kindness to place in my 
hands a large number of Brachiopods for classification which 
he had collected off the coast of South Australia. For this 
I tender him my best thanks. The material embraced, be- 
sides well-known species from these waters, such as J/agel- 
lania flavescens, Magusella cumingi and Kraussina lamarek- 
tana, two Magasellas and one Cistella. About the first two, 
Dr. Verco properly presumed that they were forms hitherto 
unknown: the last he believed was Cistella cuneata, which 
from want of material for comparison is easily explicable. 
This species is also new. I give below an accurate descrip- 
tion of the three species, and remark as follows: —Some 
authors question whether Brachiopods of the type of A/aga- 
sella are independent forms, and are only immature stages of 
Terebratella—even though becoming sexually mature—but 
I hold this view is not correct in all cases. Among the 
examples of Magasella vercot described hereafter, and also 
among the examples of 1/. cumingi sent to me by Dr. Verco 
are found, in considerable number, those which present all 
the marks of quite full-grown animals, especially a striking 
thickening of the shells in part, with loss of much of the 
more delicate sculpture; so that any further development of 
these forms is with certainty excluded. The genus Magasella 
is to be retained. [ will return to this in fuller detail in 
another place.
