ANNELIDA POLYCHJ5TA. 
The following species are recorded as new to Britain by 
MHntosh, 1 . c, p. 251 : — 
Harmotho'e longisetis, Griibe ; Sigalion limicola, Ehl. ; Kephthys ciliata, 
0. F.M.; Gcnctyllis lutea^ Mgrn.; Anaitis Icosterie^isis (?), Mgrn. ; Lumhrinereis 
frayilis, 0. F. M.; Omiphis sicida, Quatr. (determined as quite distinct from 
O. tubicola, 0. F. M.); Eo7ie nordmamiij Mgrn.; Scoloplos armiger, 0. P’. M.; 
Naidonereis quadriciispidata^ Fabr. ; Trophonia glauca, Mgrn. ; Chcetopterus 
noj'vegiciis, Sars ; Scolecolcpis ciiTata, Sars; Axiothca Mgrn. ; Praxilla 
gi’acilisy Sars ; P. prcctermism^ Mgm. ; Clymene ehiensis, Aud. &: Edw. ; Am^ 
pliareie arctica, Mgrn. ; Sahellides sr.rcirrata, Sars ; Grymcea hairdi^ Mgrn. ; 
Euchone analis, Kroyer ; Chonc mftmdihuliforrnis, Krbyer. 
Claparede’s list of species met with in the Gulf of Naples is 
too long to give here. 
M. Milne-Edwards mentions the fact that Savigny^s de- 
scriptions of Annelids were taken from specimens preserved in 
alcohol. Compt. Rend. Ixvi. p. 121 (January 1868). 
Aphroditidea. 
Pontogenia, g. n., Claparede, 1. c. p. 57. Antenna mediana multiarticulata 
antennae laterales nullse ; ociili pedunculis suffulti ; dorsum tela tomentosa 
tectum ; setae ramorum dorsualium crassae, apice obtuso, flabellum efficientes, 
nunquam glochideae ; setie ramorum ventralium perpaucae, bidentatae. Maxillae 
nullae. P. chrysocoma, Baird. This genus is not easily to be confounded with 
any other. It diflers from Ha'mionc by the conformation of its bristles; and its 
general configuration is very unlike. It approaches Aphrogenia^ Kinborg ; 
but to admit it the diagnosis of this genus must be altogether altered. 
Lcpidoplctirm, g. n., Claparede, /. c. p. 105. Pohyhpidm eljtris mediocri- 
bus utrinque imbricatis, partem vero mediam dorsi non tegentibus. An- 
tennae laterales nullae. Palpi longi. Maxillae corneae validissimae. L. in- 
clusifSj sp. n.. Claparede, 1. c. p. 105, pi. 6. fig. 4. V’ '■ * ’ ■ 1
