MOLLUSCOIDA. 
The Brachiopoda of the North-west coast of America, from California 
to Alaska, 8 species of Terehratulidce^ 1 RTiychonella^ and 1 Lingula {filot- 
tidia) are enumerated, and their bathymetrical distribution indicated ; 
Dali, Sci. Results Expl. Alaska, iii., and P. Ac. Philad. 1877, pp. 156-169. 
Terehratula cernica (Crosse) is the only Brachipod hitherto known 
from Mauritius and adjacent islands ; Lienard, Faune malac. de I’ile

Waldheimia. The development of the skeleton is the subject of a 
paper by H. Friele, Arch. Math. Naturvid. ii. pp. 380-386 [not seen by 
the Recorder]. 
Waldheimia dilatata (Lam.) from Kerguelen Island ; E. Smith, Transit 
Venus Exp., Moll. p. 26 [anted, p. 6]. 
Terehratclla sanguinea (Chomn.), found at the island Sorong, N.W. of 
Now Guinea ; Ann. Mus. Genov, ix. p. 293. 
Magasella. Ball, Sci. Res. Exp. Alaska, iii., points out that each 
known species of Magasella resembles very much in all external char- 
acters another Terebratulid living in the same region, and can only bo 
distinguished by the internal skeleton, but he cannot decide as to their 
real relations. 
Magasella radiata, sp. n., id. 1. c., p. 159, Shumagin Islands. 
Megerlia Jeffrey si, Dali (Ismenia), 1871, Semidi Islands, Alaska, from 
165-345 fathoms, is perhaps a deformity of Waldheimia cmwiuw, occasioned 
by want of calcareous matter ; id., P. Ac. Philad. 1877, pp. 158 & 16 9.

TUNICATA. 
R. Garner endeavours to point out morphological homologies between 
the Tunicata and the Mollusca, comparing the endostyle of the former 
with the crystalline stick of some Bivalves, and even with the chorda 
dorsalis of the Veriebrata, the tail of the larvae of the Ascidians with that 
of Carinaria, &c. Ann. N. H. (4) xix. pp. 357-380. 
W. Salensky has described the process of budding in Sal^fu afri- 
cana (Porsk.) and some other species, and comes to the following conclu- 
sions and comparisons. Contrary to Kowalewsky, the individual organs 
of the bud have, according to him, no special connection with the like in 
the mother, though they take their origin in the prolongation of the same 
original layer, endoderm or ectoderm, which has given origin to the same 
organs of the mother. He refutes also the statement of some former 
authors that the new individual is formed by two buds. As to develop- 
ment, Salpa is nearer Pyrosoma than the Ascidians. The branchial sac of 
the latter belongs originally to the intestine, as in Appendicularia ; the 
clefts in it area peculiarity of the Ascidians, which have no morphological 
relations either to the openings of the branchial sac in Appendicularia
