Contributions to Faunas. 
34 species of Tunicata and 6 of Polyzoa, observed at St. Malo and Roscoff) 
N. France, are enumerated by Orube, JB. schles. Ges. xviii. pp. 03 & 64. 
Fischer mentions Argiope decollata^ cistellula, and capsula, Meget'lia trun- 
cata and Terehratulina caput-seipentis as found on the western coasts of 
France : J. de Conch, xviii. pp. 377 & 378. 
The same author (Act. Soc. L. Bord. xxvii. pp. 1-70, also published sepa- 
rately) has observed 50 species of Bryozoa on the S.W. coasts of France ; he 
remarks that these agree somewhat more with the British tlian with the 
Mediterranean fauna, and is disposed to doubt Busk’s identifications of Bryozoa 
from very difierent parts of the world, and of recent species with species of the 
cretaceous period. 
24 species of simple and compound Ascidians, observed on the shores of 
New England, are described and figured (woodcuts), by Verrill, Am. J. Sc. 
(3) i. pp. 64, 93, 211, 288, & 443. 
The Brachiopoda of the Caribbean Sea are enumerated, and those obtained 
during the United States Survey Expedition, in charge of Pourtales, fully 
described by Dali, Bull. Mus. C. Z. iii. no. 1, pp. 1-42, pis. 2. 
15 Japanese recent spp. of Brachiopoda are discussed by Davidson, P. Z. S. 
1871, pp. 300-311, pis. 30-31. 
BRACHIOPODA. 
Terebratulidas. 
Morse has published in extenso his observations concerning 
the early stages and development of Terehratulina septentrionalis 
(Couth.) \cf. Zool. Rec. vi. p. 593], stating that the apparatus 
supporting the arms is at first similar to the circular lophophore 
of the one, and afterwards to the bilateral lophophore of the 
other order of Polyzoa ; he compares the brachial fold with the 
calice in the higher Polyzoa, the fold bordering the mouth with 
their epistome, the divaricator muscles of Terehratulina with 
the retractors of the Polyzoa, &c., and maintains his view that 
the Brachiopoda are true Articulata, having near affinities to 
the Vermes and Polyzoa. Mem. Dost. Soc. ii. part i. no. 11, 
and Ann. N. H. (4) viii. pp. 414-427, pis. 15 & 16. DalPs 
objections to Morsels theory answered : id. Am. J. Sc. (3) i. 
pp. 136-138; Am iv. p. 510.
