ZOOLOGICAL LITERATURE. 
PeropJiora. Keferstein makes some observations bn the con- 
tractions of the heart in this genus. Bericht deutsch. Naturf. u. 
Aerzte, Giessen, 1864, p. 165. 
Schizascus (Stimpson). J. Alder (Ann. & Mag. Nat. Hist, 
vol. xvii. 1866, p. 153) points out Lacazc-Hatliiers’s mistake in 
giving a new name {Chevreuluis) to this genus; and O. A. L. 
Mbrch (ibid. p. 313) believes that the same genus is distinctly 
indicated by Ehrenberg (1828) in the introduction to his Sym- 
bolae Physicai,^ thus : quod formam animalium novam 
attnlimus [Rhodosoma verecundum) Ascidias bivalvibns Mollnscis 
externa etiam forma adnectentem, Ascidiam scilicet tunica 
cartilaginea bivalvi indutam*;^^ he also fancies that Linnicus^s 
Astcrias (lunata) semiorbiculata (Amoenitates Academicae, iv. 
p. 256. n. 44. fig. 14) may have been founded on a dried speci- 
men of Rhodoso7na. 
. Salpa, MHntosh gives an account of the occurrence of seve- 
ral species of this genus off the Hebrides in August 1865. At 
the beginning of August S. runcinata was the only species met 
with; about a fortnight later, 8. spinosa (Otto), both the solitary 
and chained forms, occurred in amazing quantities. The climax 
of Salpa-life was about the 32nd of August, the sea being un- 
usually calm and the weather very line ; in some parts the sea 
resembled boiled sago for long distances. Several young forms 
{8. runcinata, spinosa) are described and figured in this paper. 
Journ. Linn. Soc. ix. pp. 41-48, pi. 1. 
Salpa cabotti. Agassiz (/. c.) describes this species at great 
length ; it is met with very frequently south of Cape Cod. 
POLYZOA. 
MHntosh (Proc. Poy. Soc. Edin. vol. v. p. 603) gives a list of 
forty -nine Polyzoa met with at North Uist in the outer Hebrides. 
Phylactol^emata. 
Parfitt mentions having found PlumatcUa emarginata, Alim., and P. fru- 
ticosa, Alim,, in the Kiver Clyst, Bishop’s Olyst. Ann. & Mag. Nat. Hist, 
vol. xviii. 18G6, p. 42G. 
^PlumatcUa Uncata, sp. n., Parlitt, 1. c. p. 172, pi. 12. ligs, 1-3, from the 
underside of the leaves of water-lilies, Exeter ; near P. st?'icta, Alim. 
Plumatella UmnaSy sp. n., Parfitt, ibid. p. 172, pi. 12. figs. 4-8, on an old 
valve of Anodon cygneus, in the canal, Exeter. 
Gymnolasmata. 
TEREBRiPORiDiE. Eischer makes this family, which is closely 
allied to the Plippothoidse, for D’Orbigny^s genus Terebripora, a 
new species of which, from the Mediterranean and Arcachon, is 
alluded to without being described ; so, also, is a new genus.
