trochan ; and the authors remark that it is impossible for th^m to distinguish 
the apparently correct delineations of the larvas of Nareda as figured by A. 
Agassiz from the larvss of Nephthys. 
CiRRATULEA. 
Cirratuliis auricapilhis, sp. n. (Ehrb.), Grube, 1. c. p. 503, Tor ; C. gracilis y 
sp. n. (Ehrb.), Grube, 1. c. p. 604, Tor ; C. nigromaculatusy sp. n., Grube, /. c. 
p. 504, ? Red Sea. 
Cirratidns chrysoderma ?, Olprd. Its development is described by Olapa- 
redo & Mecznikow, 1. c. p. 192. 
Andouinia JUigora {Jjumhricus fdigcruSy Dcllo Ohiajo). Its development is 
described by ClaparMo & Mecznikow, I, c. p. 102. 
ClILORiEMEA. 
Siphonostoma busJcii, sp. n., MTntosh, 1. c. p. 420, pi. 16. fig. 13 & pi. IG. 
fig. 4, Lochmaddy, North Uist. 
Lycoridea (Nereidea) 
Nereis massiliensis, sp. n., M. Tandon, 1. c. p. 870. Described as an herma- 
phrodite species. 
Nereis fasciata, sp. n. (Ehrb.), Grube, 1. e. p. 498, Red Sea. 
Heteronereis grandifolia, Mgrn. The agreement between this species and 
Nereis pclagica is in many points so surprising that Malmgren (/. c.) considers 
it to belong to the same generation-series ; while, on the other hand, H. 
fucicola appears to be combined with Nerdilepas vaiiahilis, (Erst. (= Nereis 
dumerili auct.), in the one generation-series. Vide also Ehlers’s remarks 
< Zool. Record,’ 18G7, p. 633. 
Iphinereis and Heteronereis. Malmgren {I, c. p. 478) suspects, from reasons 
given, that the species of these genera are but sexual forms of still unknown 
genera. 
Syllidea. 
Syllis vivipara, sp. n., Krohn, 1. c. p. 198. Very closely related to S. ar- 
mandiy Clprd. This species is viviparous.

Shetland. 
riiyllodocc macnlatay Johnst. MTntosh {l.c.) describes and figures the 
development of this species from the time the ovum is impregnated to about 
its fourteenth day. 
Phyllodoce. The development of a species of this genus is described by 
Claparede & Mecznikow, 1. c. p. 189.
