New Genera and Species, &c. 
Grube (44) describes the following new fovm^ :—Lmtifnonice producta, 
Polynoe vesiculosa^ P. fullo. P. pycnolepis^ Panthalis hicolor, Sthenelais 
incisa, Sigalion amboinensis, Psa^nmolyce mnhonifera, Nereis {Ceratonereis) 
divaricata, Vanadis greeffiana^ Syllis buchliolziana^ Hyalinoecia platyhran- 
chis, n. hrevicirriSy Eunice complanata, E. dilatata, Lumhriconereis am- 
hoincnsis, Goniada congoensis, Nephthys trissophyllus, N. modesta, N. 
dibranchis, Cirratulus atro-collaris, Spiochcctopferus tropicus, Maldane 
decorata, Trophonia kerguelarum, Terebella {Loimia) ocTiracea, T. (Phry- 
zelia) bilobata, Sabella costulafa, S. torquata, Serpula patagonica, Lum- 
bricus herguelarum, L. tongaensis, PericTiceta suhquadrangula. 
The new genera are : — Lamproderma (Hesionidce), p. 525 ; L. longi- 
cirre, New Britain. Pycnoderma {Chlorhcemini), p. 540; P. congoense, 
Congo. Phyllocomus {Ampharetei), p. 543 ; P. crocea (between the 
Crozets and Kerguelen). 
Thelepus, Leuck. (char, emend., Mgn.), and Neottis, Mgn., are united 
on the ground that the possession of one more branchiferous segment by 
the latter does not justify their separation ; and, as there is a T. ant- 
a.rctica, Kinberg, the N. antarctica of McIntosh must have a new specific 
name, and Grube suggests mlji^cintoshi.
